Review: The Geometron G1 is Designed to Be Future-Proof & Adapatable

Jun 14, 2021
by Seb Stott  

Geometron is a partnership between German frame builders, Nicolai, and Chris Porter - a motorcycle journalist turned World Cup tech turned suspension tuner, long-bike pioneer and opinion-haver. Back in the day he made waves arguing that 29ers were pointless (I remember having a two-hour argument with Chris about that topic in 2015) and that we were all riding bikes that were too small, too steep and too slack in the seat angle. The Geometron started as a way of getting a bike Chris actually wanted to ride, and perhaps proving a point at the same time. At first it raised many a skeptical eyebrow. But now the geometry they pioneered is largely accepted, and even replicated, by the wider industry, and few would argue for a return to shorter, steeper bikes with slacker seat tubes.
Geometron G1 Details

• Wheel size: 27.5", Mullet or 29"
• Travel: 160-200mm front, 162 or 175mm rear
• 62.5-degree head angle
• 79-degree effective seat angle
• 450mm chainstay
• 1,345mm wheelbase
• Weight: 37.7 lb / 17.1 kg (XL)
• Sizes: Long, Longer, Longest, Extra Longest (tested), XX Longest
• Price: £5,950 (For off-the-shelf XT build)

As for the 29er part? Well, everyone's wrong about something.

After Chris's company, Mojo Suspension, parted ways with Fox, Chris setup Mojo Rising with six staff, focusing on Geometron bikes and distributing Formula and EXT suspension.

Until recently there were three options in the Geometron line: the G13, G15 and G16. These have 130mm, 145mm and 155mm of travel, respectively (although the G16 can be run with 175mm travel with a longer shock). The G1 was developed in 2019, and while the name of the other bikes indicates the travel, the "1" in G1 refers to the idea that it's one bike to do everything. According to Chris, Mojo Rising staff were riding the longer travel G16 for everything including long cross-country rides, and you don't need less travel for less technical terrain, just faster-rolling tires.

The G1's "modular" design means it can provide 162mm or 175mm of rear travel with the same shock; accommodate forks from 160-200mm, plus any wheel size configuration you like and a choice of three chainstay length options. With all this adjustability it's designed to be future-proof and adaptable enough for everything - just as long as your idea of everything doesn't involve low weight.

So sure are they that the G1 is all you need, Nicolai no longer make the G13, G15 or G16. "We can make it fit and work for more people in more types of situations," Chris tells me "The G1 is just better!"

Equally important as geometry is the suspension. Mojo Rising worked with Nicolai to fine-tune the kinematics - which have been refined, not revolutionized - since the original Geometron. They've also worked with EXT to provide highly-customized versions of the EXT Storia V3 shock. But perhaps the biggest USP they have for those in the UK is the setup/demo rides and service they offer.

Mojo Riding staff can set up the bike with you from their HQ near Monmouth before heading out for a test loop, during which you can try out different spring rates and suspension settings, geometry configurations, components and even different frame sizes. Can you imagine that from a mainstream brand? Having done this myself with the G1, the experience they have from setting up hundreds of Geometrons for a range of customers, plus the trail-side perspective on your riding, can be immensely valuable even for someone who's confident and experienced setting up bikes for themselves.'s when trucking over rough terrain where the G1 is in its element. The rougher, the more hectic, the better. Seb Stott


Construction and Features

The G1's frame is all about options. The interchangeable seat stay mutator chips act like conventional flip chips in that they alter the ride height and frame angles simultaneously, except by swapping out chips of different lengths they can theoretically offer eight ride height options. These can be used to compensate for a 27.5" or 29" rear wheel without affecting the geometry, or can be used to change the BB height and frame angles interdependently of wheel size.

The chainstay mutator offers three options for the chainstay length (446mm, 453mm or 458mm). The stock configuration changes by frame size, but there's nothing to stop you running any chainstay length on any frame. The chainstay mutators also affect the BB drop slightly, so it's recommended to change the seat stay and chainstay mutators together if you want to preserve the BB height. This can get pretty complicated, but this spreadsheet on Geometron's website shows all the combinations and their effects.

The shock link has two eyelet positions, offering 162mm or 175mm of travel. The longer travel setting is also slightly more progressive, so the Mojo Rising staff generally recommend the 175mm setting with more sag and similar mid-end stroke support. As if that weren't enough, the G1 is available with an external lower headset cup which allows it to run a 27.5" front wheel with the same geometry. So 27.5", mullet and full 29" setups can be accommodated without affecting the geometry (unless you want to). In theory, you could even run a 27.5" front wheel with a 29" rear, though that's not recommended.

The black anodized block between the rocker link and seatstay is the seatstay mutator chip, which affects the BB height.

The chainstay mutator sits between the chainstay and Horst-Link pivot. Three options provide three chainstay lengths.

The shock is mounted on spherical bearings which allow the shock to move more freely with less side-loading, and so less friction, as the frame flexes. Cable routing is fully external (except for the dropper cable), with custom aluminum clasps to hold the cables in place. No zip-ties here.

Spherical bearings allow the shock to twist interdependently of the frame to reduce binding and friction as the frame flexes.

Thick flat scaled welds and external cable routing with industrial mounting hardware are Nicolai hallmarks.

The frame is constructed from 7020-T6 aluminum for its high tensile strength. The raw frame isn't afraid to show off its flat scaled welds, which are produced with a very slow welding speed and multiple passes, which Geometron claim reduces distortion and improves longevity and strength. Less visible are the rubber seals in the bearing preload caps, which are designed to prevent water ingress and improve the longevity of the pivot bearings.

The frame has an industrial, even overbuilt feel to it. The rear thru-axle has a hexagonal nut so it can be used with a spanner or a 6mm Allen key, the seat stay mutator chips are each held in place with two long steel bolts and the reinforcement around the head tube, shock mount and bottom bracket are seriously substantial. I didn't weigh the frame on its own, but aside from the fork the bike I tested has a reasonably light build so a lot of the 37.7 lb / 17.1 kg weight is in the frame.

There is space for a water bottle in the Xl frame, so it should be possible to find a better solution than this!

One feature which is missing is a bottle cage, but on the XL there is space to fit one in front of the shock mount if you get creative. It's also worth noting that tire clearance is relatively tight. The bike is pictured with 2.6" Schwalbe Eddy Current rear tire on a 25mm rim (actual tire width was 64mm or 2.52"), which is a tight fit.


Geometry & Sizing

Because the G1's geometry is so adaptable the above table is really just a starting point. On my XL I measured the BB height at 335mm from the floor. The head angle was a little steeper than stock due to the short axle-to-crown length of the MORC 36 dual crown fork, measuring around 63-degrees depending on how the fork was setup. I stuck with the 453mm chanistay setting throughout testing, but swapped back and forth between 27.5" and 29" rear wheels using different seatstay mutators to maintain the same BB height.

At 190cm tall, I'm on the border between the "longest" (large) and "extra longest" (XL) frame size. "We usually set up both large and XL for a rider of your height to try out," Chris told me, "Or on a ‘distance sell' we would probably spend a bit of time on the phone checking measurements on the current bike and body measurements. Most people at that height are sizing up." Chris also added that clipped-in riders (like me) are more likely to size up as they typically ride more forward.

I've ridden XXL and a Large Geometrons in the past and to a large extent it's possible to adapt to all three. Though there were big time gaps between riding each one, I'd say the XXL was too much work for me when it comes time to manual and hop over trail obstacles. The Large felt big enough when I rode one a few years ago, though its numbers are comparable to a modern XL enduro bike and I'm not sure which suits me better now between the L and XL.

Suspension Design

The G1 uses a Horst-link arrangement, which delivers 33% progression from start to finish in the 175mm setting, and 30% at 162mm travel. That's on the more progressive side, which plays nicely with coil shocks. The leverage ratio drops off smoothly throughout the stroke, resulting in a consistent increase in wheel rate (the suspension stiffness measured at the wheel) throughout the travel.

The lower leverage curve is for the 162mm travel setting; the top one is for 175mm. Note the horizontal axis is the shock stroke, not wheel travel, which is why both curves end at the same point.

There's just over 100% anti-squat at sag which keeps the suspension from bobbing too much on climbs, though there's slightly more movement than some enduro bikes with higher levels of anti-squat, like the Privateer 161.

The custom-tuned EXT Storia V3 shock is set apart from the standard unit with its coil negative spring inside the damper in place of an elastomer top-out bumper. In the absence of the main spring, this pushes the shock into its travel a few millimetres. The preload on the main spring can then be balanced against this and so adjust the ride height without introducing any breakaway force like you'd get when using preload on a conventional shock. The negative spring also counteracts the spring force coming from the nitrogen charge behind the IFP, so there's zero breakaway force to overcome to get the shock moving from the start of the travel aside from friction. Chris recommends running the preload light enough that the shock sits into its travel under bike weight, but extends to the point where the main spring has no preload and goes loose when the bike is lifted off the ground and the weight of the rear wheel acts to extend the shock.

This means the "positive travel" measured from how the bike sits under its own weight will be less than fully extended, but the suspension has the ability to extend further when the rider pulls the bike up or the rebound overshoots. In my case, the bike was set to the 175mm travel setting, but about 10mm of travel is taken up just under bike weight. The 335mm bottom bracket height was measured under "bike sag".

The shock has a hydraulic bottom-out circuit, which progressively increases compression damping in the last 11mm of shock stroke (25mm of wheel travel) to resist bottom-out. This allows a small bottom-out bumper to be used. It also gets custom valving for the G1, with lighter low-mid speed rebound valving to allow faster recovery. Chris claims the negative spring allows the rebound to be set faster by resisting rebound before top-out is reached. The low-speed rebound is externally adjustable by hand, the low-speed compression requires an Allen key and the high-speed compression requires a spanner for adjustment. A climb switch closes off the low-speed compression to give a moderately-firm pedaling platform which easily opens up over larger bumps.

The compression damping requires tools for adjustment.

16.04.21. Pinkbike Forest of Dean Rider Seb Stott. PIC Andy Lloyd
The fork is based around standard Fox 36 lowers and RC2 damper, with custom stanchions, air spring and offset-adjustable crowns.

There's no such thing as a stock build with the G1. The suggested build kits listed on the website are there to stop customers being overwhelmed with choice, but customers are encouraged to order off-menu; for example, you can have a 170mm Formula Selva or EXT Era fork, Hope or Formula brakes or supply some of your own parts.

One thing on my test bike that might be hard to get hold of is the fork. The MORC 36 kit adapts a Fox 36 lower and damper with dual-crown upper tubes and offset-adjustable crowns (MORC stands for Mojo Offset Reduction Crown). They can be run with 41.5, 44 or 46.5mm offset, and are claimed to increase stiffness. The longer upper tubes also provide room for Mojo to go to town on a custom high-volume air spring. The lower compression ratios in both positive and negative chambers make for a very linear spring curve, with ample room to adjust the end-stroke progression with volume spacers. Separate valves for the positive and negative chambers allow the ride height and off the top suppleness to be fine-tuned via the difference in pressure between the positive and negative spring. The fork works best with the negative spring over-pressurized by at least 10psi, which causes the fork to suck down into its travel by about 20mm,leaving only around 150mm of usable travel to play with and a short axle-to-crown length.

One component choice which may stand out is the 2.6" Schwalbe Eddy Current rear tire. In order to compare 27.5" and 29" rear wheels I needed tires with identical specs in both sizes, and the Eddy Current was the only tire I could get hold of which fitted the bill. As it turned out, the true width was closer to 2.5", which worked fine on a 25mm rim.

Test Bike Setup

After trying out a few different spring rates I settled on 475lb/in on the shock, with the compression damping fairly open and the rebound towards closed (it's still pretty quick). With the fork, I started with 100psi in the positive and 110psi in the negative, but incrementally increased this to 120/130psi to get more support and hold it up higher. To compensate for the fork's short axle-to-crown length, I fitted a 25mm stack of spacers under the stem and a 40mm rise bar to bring the handlebars up to a comfy height of 111-112cm.

After I had arrived at this setup I went to Mojo rising for a setup ride to get the full customer experience. After watching me ride past a few times, they suggested increasing the fork pressures to 130/140psi, swapped the 475 for a 450 lb/in spring in the shock and reduced the preload slightly to stop the fork pushing through its travel in the turns and transfer more weight to the rear wheel mid-corner. They also sped up the rebound front and rear and increased HSC on the shock to stop it using too much travel on bigger hits.

This setup created a better balance when riding aggressively - over the front and pushing into corners. But the firmer fork made it more important to consciously weight the front wheel on flat terrain.

I spent a lot of time swapping between 27.5" and 29" rear wheels, using seatstay mutators to maintain the same geometry, to find out what difference the mullet makes (feature to come). As a result I didn't experiment with the adjustable offset (I kept it at 46.5mm), with the longer of two stem length options (32.5mm) and stuck with the 453mm chainstay.

Tire pressures were 22-24psi front, 26-27psi rear.

How does a 17.1 kg bike with a dual-crown fork climb? Much better than you might think.

Let's start with the fork. I didn't find any climbs where I ride in South Wales where the steering limit of the fork made it impossible to get round. That said, if you live somewhere with tight Alpine switchbacks this may be a problem. And on technical climbs when the wheel slipped out I found myself running into steering lock when trying to regain balance on a couple of occasions. Turning around on a fire road isn't easy either. The 36 fork stanchions are closer together than purpose-built dual crown forks which, combined with the long wheelbase, means the turning circle is wide. But during normal riding this is rarely an issue.

As for the weight, it's maybe a kilogram heavier than an average XL enduro bike with similar tires and coil shock. For a bike and rider weighing 100Kg combined, that's 1% more weight to bring up the hills, so it'll take 1% more power or 1% time. I'm not trying to tell you the weight is a good thing, just that it's not as big a deal as some may think.

It really doesn't feel especially heavy once you get pedaling. What you can feel is the position is super comfortable, with the hips nicely over the bottom bracket when attacking steep climbs. And thanks to the long reach, the cockpit still feels nice and roomy, so my shoulders and arms were relaxed. There's enough anti-squat to keep the suspension from bobbing much when pedalling normally, but the suspension is very free to move when pedaling over bumps. It's not the snappiest when stamping on the pedals, but you can always flip the climb switch if you want a firmer feel. Leave it open and the G1 delivers loads of traction and composure when tackling rough climbs. The steep seat angle means you can remain seated to better manage traction on the steepest climbs around. So while you may get to the top a few seconds later than on a lighter bike, you'll likely get there without having to push.

To illustrate the point, I rode the same steep climb on a Focus Jam, a 150mm-travel trail bike, and the G1 on the same day. The Geometron made the climb much easier because I didn't have to waste energy hunching forward or getting out of the saddle to stop the front wheel lifting.

The slack head angle means there is some wheel flop when turning tight at slow speeds (where the steering creates a force away from straight ahead), but I never find this a problem.

I spent a lot of time riding the G1 as fast as I could through tight and fast turns to figure out the difference in handling between the full 29" and mullet setup. With either rear wheel, the G1 was remarkably agile in the turns if ridden aggressively. That wheel flop due to the slack head angle means the steering "wants" to tip into the turns, while the low bottom bracket helps it to lean in and out of the corners more quickly. After getting used to the bike I was able to really push on, hitting familiar alternating berms harder than I had before. When pushing into these short, sharp turns there was plenty of support to push against, but with the fast rebound tune the bike would almost jump from one turn to the next. It's not uncontrolled, but there's definitely a springy feel when pushing off short berms.

The long front-center means you can't be shy about getting your weight over the front, otherwise the front wheel is too lightly loaded and won't grip well. This makes the G1 hard to handle if you ride it timidly or hang off the back. But bend your elbows and get your weight forwards and it will reward you with lots of grip and stability, particularly in rough, rutted or steep turns. In an ideal world, you'd want a 50:50 weight distribution between the wheels, and the long front-center means you have to put more weight on your hands to achieve this. But with your weight halfway between the axles, there's more room in front of you with a longer bike, which means the bike pitches and "trips up" less when braking or hitting bumps, and the slack head angle and high trail figure mean the front never tries to tuck or jackknife. For me this makes it easier to "trust in the front," which means I stay tall and centered on the bike when things get steep and gnarly, resulting in better front-end grip than a shorter bike, where I'm more likely to hang off the back.

On the other hand, when I was having an off day, riding tight or timid, the XL G1 can be a handful. This is why some riders at my height might want to size down to a Large, and if I was considering buying a G1, I'd arrange to try both sizes on the same day.

While cornering takes some getting used to, it's when trucking over rough terrain where the G1 is in its element. The rougher, the more hectic, the better. Small bump sensitivity is superb, so the bike takes the sting out of all the small chatter and sticks the wheels to the floor. And when the rear wheel is unweighted, for example when braking or on the backside of bumps, the extra room to extend on rebound allows it to stay in contact with the ground better, which helps to maintain control.

While I've never back-to-back tested spherical bearings against normal bushings, when hammering through a pinball rock section I've ridden countless times, the bike as a whole works so well I could be persuaded they were doing their job. The extra weight of the frame no doubt helps a little in these situations too, as anyone who's ridden an e-bike will know.

The setup Chris suggested with the slightly softer 450lb/in spring and firmer HSC is all about traction and support, but less about comfort. Inevitably, when hitting square-edge hits it sometimes transmits a bit more feedback than you might get from typical digressive compression tunes with less high-speed compression. This seems like a small price to pay though. Despite the firmer high-speed damping and bottom-out circuit, I still I found the bottom of the travel a few times, but not harshly.

The MORC 36 fork wasn't quite as impressive. When setup with enough negative pressure to make it nice and soft off the top, it's only serving up around 150mm of travel. I did try using less pressure in the negative to get it to sit a bit higher, but this ruined the linear feel which is at odds with the rear end. After increasing pressures in both chambers and speeding up the rebound on Chris' recommendation, the fork provided good support and traction, but with the RC2 damper and firm mid-end travel feel it isn't exactly comfortable or forgiving for long descents, particularly when compared to the 170-180mm travel forks I'm used to. But, as with the bike as a whole, if you ride it hard it makes more sense. The fast rebound helps it deal with high frequency bumps without bogging down at all.

The low sagged BB height and long wheelbase make it pretty easy to sump out the chainring on steep rock steps, so a little more care is required on awkward terrain. Clipping pedals is easily done too, so the G1 prefers carving corners and carrying speed over squaring them off and snatching pedal strokes in between.

And while the attention to detail as far as suspension performance is second to none, it's not as refined in some other ways. Despite the coil negative spring, the lack of an elastomer top-out bumper means that, especially if you ride clipped-in, it tops-out with a clunk when hopping over big obstacles like tree stumps. And when rattling over rough terrain there is more chain noise than most modern bikes, even with the derailleur's clutch on.

Geometron G1
Privateer 161

How does it compare?

I've spent a lot of time on the 161 over the past year, so most of the trails I rode on the G1 I've also ridden on the Privateer. Like the G1, it's a bike for people who aren't too fussed about weight but want new school geometry. My 161 with a Fox 38, alloy wheels and Schwalbe SuperGravity tires weighs 16.3 kg, so a little lighter than the G1. The 161 has an even steeper seat angle (80 degrees) and considerably more anti-squat, which makes it feel a bit more "sporty" when sprinting or mashing the pedals on the steepest climbs. As I said, the G1 is far from inefficient though, and 79-degrees is plenty steep enough, but if faced with a long climb I'd still prefer the Privateer.

The XL Privateer is only 15mm shorter in the front-center and has the same chainstay length, but it feels a bit more lively on the trail and demands a bit less proactivity from the rider. The longer stem (40mm) and slightly shorter front end mean I don't have to remind myself as often to keep plenty of weigh over the front when riding flatter trails. The flip side is the G1 has more of a feeling of steering from behind the front wheel with its shorter stem and slightly slacker head angle, which makes it feel that bit more unshakable when tackling big rocks or steep catch berms. Ultimately, this comparison shows how far other brands have come: the 161 has near-identical BB height, chainstay length and seat angle, while the wheelbase of the XL Privateer falls in between the Large and XL G1. As a result, the handling is not worlds apart.

The rear suspension on the G1 is a little more planted at the rear, although the Fox 38 offers plenty of stiffness and early-travel sensitivity without the steering lock and travel limitations of the MORC 36.

DT Swiss EX471 rims

Technical Report

Formula Cura 4 brakes: After a bleed the Cura 4 brakes were impressively powerful, with a short free stroke and a sharp lever feel. I'm a big fan of the more punchy bite point over the more modulated feel of a Code, and the bite-point consistency was faultless. The only downside is that you couldn't squeeze a pensioner's payslip between the pads and disc, so setting them up without any scuffing is next to impossible.

DT Swiss EX471 rims: 25mm wide rims are still ride-able, even when running a 2.6" tire on the rear. But I had to add a psi or two to stop the tires squirming in turns, which I rarely find a problem with 30mm rims even at pressures where I'm occasionally hitting the rim on rocks.


+ Superb traction and composure in hectic terrain
+ All of the adjustability
+ One-to-one setup rides could add enormous value if you can get to Mojo Rising HQ


- Long geometry demands a proactive and assertive riding style
- Not for weight watchers
- Occasional top-out clunk and chain rattle
- No water bottle mount

Pinkbike's Take

bigquotesWhile the geometry of the G1 is still that bit more boundary pushing than the rest of the pack, and the suspension and composure is really impressive, what really gives Geometron a distinct advantage is the breadth of tuning options, combined with the setup expertise and support provided by Mojo Rising. If you can go for a demo/setup ride, their experience in fine-tuning these bikes can be really helpful even if you're well-versed in setting up bikes on your own. Setup is so important with any bike, so having that one-to-one help could be worth a lot. Seb Stott

 I've had one for over a year now, and I'm on an XL, 6"4" 194cm.
Agree 100% with the need to ride it hard, its not a cruising around kinda bike, hanging off the back in proper trails leads to bad outcomes Smile
I went to Geometron HQ for the custom fit, and it's mindblowing how much of a difference it made in terms of shock setup to virtually eliminate bobbing when pedalling with the climb switch off, handlebar height, brake angle, BB height, fork setup.

Love my G1, best bike I've had to date.

 I've got one too. It's overkill for trail centres imo, but imperious in steep natural stuff, particularly if grip is low and it's off camber.
(I spent pretty much the entire demo ride sliding around on wet leaves wondering why I was still upright. I put the order in soon after.)

I will second the demo service as well - I tried mine set up as a 29er and mullet and the two ride very differently. It's well worth the trip to get it set up properly. It's a bike that isn't for everyone, so it's worth a try to see if it suits you when set up for your riding style.

 I find it puzzling, when these super long bikes are sold with the disclaimer that they are for "the agressive, assertive, advanced rider" when the pros are all riding 40-50mm shorter bikes.

 People are still skeptical of the dimensions and geometry, but look how close the new Transition Spire is to this bike. Commencal is getting close too. Also, considering there is a thriving industry of brands that exist to modify existing geometry, the ability to adjust and change aspects of this bike is undersold. As one commentor has pointed out, and as Paul Aston did, you can run this at 210mm of travel in the rear just by switching out the shock, and keep the geometry fairly constant with the mutators.

Also, with regard to the weight, Nicolai/Geometron is not shy about that. This bike is intentionally built like a brick shithouse. That is a plus for some people, especially those who know they could save 10-20lbs going uphill by drinking less beers after the ride and in general.

But it sucks at skinnies, wheelie drops, and an XXL is too long for most bike racks without some jerry-rigging. So there is that.

 560mm reach on the XXL. Would recommend to any basketball players. I’m not sure many companies will ever go that far. There’s no prefect geometry combinations there’s always a compromise.

But looking further than 20 years ago geo weren't sorted out and it took from the 50's to the early 2000's to be actually sorted. Now granted DH mtb could have taken much more inspiration from MX to get where we are now faster but then again, HA has been sorted since 2010, many people were already over sizing to get more stable bikes and if people didn't mess up with shit like wheel sizes or boost whatever they could have focused on figuring out proper geo which is way more important. Probably harder to pitch/sell tho.

Definitely don't feel the weight on the trail and especially so with a 30T ring paired to a 10/51 cassette. Same set up with swapping the little wheel on the front brings it to 79/63ish range. At 35-36lbs with pedals and inserts I really don't see that being too heavy for a 175mm travel enduro/dh bike

 I hear the phrase “weighting the front” being thrown around a lot now with longer front centers. Really your weight should be on you feet not your hands. Just watch Sam Hill.
  • 4 0
 Exactly, maybe it is easier for people who clip in. But honestly I would never want a bike which requires me to focus on weighting the front, bacause the second you let go on a trail with a bit less grip, you are down. And not many of us can constantly charge, sometimes one need a chill ride just to recover.
  • 16 1
 I've got a G1. I'll be honest in that I can't corner like Sam Hill, but with that out of the way here's my take...

It's not requiring you to put all your weight on the front. You still predominantly weight your feet, but if you're dropping into a switchback you can't be scared and lean back - you need to commit and keep your weight central (a bit like skiing). I found that, for me as a 6'3 chap coming off a shorter and steeper bike, it very much feels that you're riding 'in' the bike, and that you have a very good feeling as to where the grip is front and rear. Drifts are gradual rather than sudden, and you can easily move your weight back or forward to control the grip. You have quite a large window of control and you can feel it intuitively. Obviously there's a combination of factors involved in achieving that, but I think the main one is the length and low bb. Hope that makes sense...
  • 2 0
 @lkubica: On my test ride I asked to ride stuff that wasn't crazy steep (I knew it would be done at that). As I said above the bike drifts beautifully and I had a great laugh on some mellow wet leaf covered trails. It excelled there.
Where it isn't so good is mellow grippy trails (trail centres) as it's a bit overkill. Depends on your local riding to decide if it suits you...
It is more fun the more actively/hard you ride it though!

 So in your opinion you should get on the bike, remain in the same position all the time and wait for things to happen ? Problem is, you can't ride a 2 wheeled vehicle this way, not if you want some performance out of it anyway. Problem is, with shorter bikes you need to be very precise in your weight shifts, because of this is makes lazy and slow riders, you can get away with staying in the middle and accept poor performance. Longer bikes allow you to have more room to move, load the front when you need grip there, move to the back when you want grip at the back or unload the front. Because it is longer you have more room for error to learn how it feels to actually pilot your bike instead of being a passenger. Try to ride a MX bike and I guarantee it will be an eye opener. Actually riding your bike isn't that much more difficult but it requires you to be active instead of being passive, since you are American, I assume you despise assistance and handouts so you should also despise short bikes that do the work for you lol.
  • 1 0
 @lkubica: With a longer reach I don't think you have to think about it; it happens passively because your centre of mass has already been moved forward. It would also make it more difficult to hang too far off the back.
  • 2 0
 @boozed: nah, that's what long chainstays do to you. If you have a 500mm reach with 430mm CS you better load that front wheel if you want the bike to corner.
  • 2 0
 @Balgaroth: I agree to a point but speaking from my own experience, I recently changed from a bike with 470mm reach, 440mm CS and 65° HA to one with 500mm reach, 440mm CS and 64° HA, with an overall increase in front centre of about 55mm. I was concerned that this would be a problem because similar bikes (e.g. the Norco Sight, which has a slightly longer CS) emphasise the need for an aggressive rider-forward riding style. In the end it turned out to be the opposite - I used to struggle for front traction and now I rarely have to think about it.
  • 1 0
 @boozed: that's interesting. Any idea how your bar and BB height have changed between both bikes ? By experience, everything else equal, longer CS help load the front end, but my latest bike taught me that Bar/BB heigh has a massive effect on how the front wheel is loaded.
  • 1 0
 @Balgaroth: Since you mention it, bar height might be a lot of the difference. The BB height is almost identical but some quick measurements indicate the grips are about 40mm higher, which I assume makes it easier to weight the front. The stem's also 25mm shorter. The new setup does feel more relaxed.

 I agree on the narrow rims, I was on 21mm rims for a long time and never felt I needed wider, I then got a new bike with 29mm rims and 2.6" tyres and it feels much better with no noticeable tyre squirm. I since got a bike with 25mm rims and 2.6" tyres and find I have to compromise with tyre pressure so I've bought a 29mm rim. Wide is definitely better IMO
  • 7 6
 Complete opposite for me. Been running EX471's and previous equivalent for years and wouldn't run anything else. Recently got a trail bike with 30mm rims and running the same set up with tyres etc felt horrible, tyre profile was so bad and just felt slow and all over the place.

 @Freakyjon: I've had the same experience as you. Much prefer 25mm especially on the rear wheel.

I tried 30mm and went back to 25/28mm, makes the bike more precise and responsive.
  • 2 0
Of course your preferred tyre width also makes a huge difference, I tend to run 2.6" tyres but if I were on 2.3" then a narrower rim might be better suited. I used to run Magic Mary 2.35" on 21mm rims and never thought twice about it and they sized up to around 2.5"
  • 2 0
 Tyre/rim combo is critical. On the front wheel I found the 2.35 MM was fine on 23mm rim, too square on 35mm. 2.5 Assegai on the same 35mm rim is amazing. I still have a 25mm rear though as I tend to use 2.3-2.35 tyres there. I call it "horizontal mullet".

 I’ve owned 2 of these, bought #2 after #1 was stolen, and they are unreal on the steep and chunky. Like, mind blowing. If it’s not steep and chunky however, they are kind of boring because small trail features are bull dozed over. Gotta ride it fast and hard all the time to get the most out of it, but the benefit is that it will go faster and harder than you. Endless traction on the downs and ups. Also it’s quite comfortable for 7 or 8 hour big mountain loops, I would choose it over a little trail bike every time. Having said all that, if I went for #3 I would size down because I like bouncing around and goofing off. Having said that, I ordered a spire because the geo is almost the same, but it holds a water bottle. And I hate my endurobro fanny pack.

Geometron does offer custom tuning, but in speaking with Chris, he told me the vast majority of Storia-equipped G1’s leave Geometron with the custom tune he helped develop with EXT, which is the same as the custom tune you get on a Storia purchased w/ a G1. This is because the custom tune works for most riders, and only if you’re outside normal parameters by quite a bit, he/they encourage you to try the tune first, and report back with issues.

 @gonecoastal: any bearing shop, same as for needle, angular, cartrige bearing, those are not made specificaly for Storia, they exist in the industry, cars, motorbikes and so on. Now is there a bearing that would fit into a standard bike shock eyelet is the right question. You'd want to check SKF, *ag or INA catalogs and see what would fit. Some specialty companies like CR Conception in France used to (maybe still do) offer some needle bearing kits to replace shock bushings so maybe the outer diam is not a bike specific standard.
  • 2 0
 @gonecoastal: i’m not sure you can simply retrofit spherical bearings into any shock eyelet. What I remember when I first learned of spherical bearings when Cane Creek introduced the double barrel shock, I had to have the eyelets bored out. While I haven’t taken my Storia apart, I have seen photos that show a C clip retaining spring that keeps the spherical bearing centered, which would point to a more complicated shock eyelet than simply a drilled hole.
I’m not sure how PUSH is doing it, but they are supposedly doing spherical bearings as well.

 @BenPea: Well I think I have to agree with Paul Aston when it comes to BBH: low bb was a good thing on short bikes but becomes less important on longer bikes. Personally I think BBH needs to be adjusted to compensate for travel and whether or not you do technical uphill pedaling. For 200mm travel I think ~360mm is pretty good. For 180mm around 350mm.
I find seat tube length to be a much more important factor which is why I have the L frame with an S seat tube length of 415mm.

 I have one. I'm 195 and run an Xl with a 50mm stem... Up from the 35 it came with. I found a longer and lower stem helped weight the front that bit more... That HA does take some getting used to. I had it set from mojo almost identical to my Pole hardtail in terms of reach and bar height. But oddly it felt short and high. It is a heavy bike - the factory spec doesn't do it any favours as hope 30 wheels are almost 2.5kg a set and a Betty rear should only ever be fitted to an eeb or a park bike. I quickly swapped for lighter wheels, smaller lighter cassette and more enduro friendly tyres. It made a massive difference. It's not a shits and giggles bike like the evil insurgent it replaced but bloody hell it's fast and so really is something else on super steep, rooty, rocky natural trails. It's like the difference between wings and slicks, vs high power low grip and sideways on a track. There's room for both. It would be shit single bike, but if you have terrain to hand to do it justice, then you'll love the sensation of speed it offers. To summarise... I would get off the Evil giggling. I get off this fizzing and wondering when I'm going to find the limits and really hurt myself . There's room in everyone's life for both... Unless you're self employed and don't have good insurance.

 Weight does affect climbing but I feel the overriding thing is just how much more knackering riding a heavy bike is , I went froma 34lb Alpine 160 to a Giant carbon Trance and I was blown away how I could ride all day not be cream crackered fter 2 hrs. This bike is probably best suited to uplift days at that weight for me anyway.

 I have a 2018 G15, which I've made a few modifications to in order to get a bit closer to G1 geometry, minus 2.5 angleset, long-shocked. I can't imagine riding another bike besides a Geometron/Nicolai. After 20 years of riding bikes too small for my tall self, it's refreshing to learn what a proper bike size should feel like. My only complaint is that the stack height always felt too low, but some Dartmoor Lightning Hi rise bars made it spot on.

 Jack Moir just posted a video that I think goes a long way to explaining this. He tested the short, steep Strive vs. the longer, slacker Spectral. He said the Spectral felt much faster and more comfortable on fast straight aways, and on tracks he was familiar with, but the Strive was much easier to change direction on the fly when he was unfamiliar with the track. He also said that while it was less stable, it was not too much harder to rally in a straight line. He also noted that on the tight European tracks, there tends to be more time to be made/lost in the tight tech than in the fast straights.

I think this goes a long way to explaining why EWS racers run short bikes. Because they only get one practice run, they are going to have to ride more 'reactively' than 'proactively', whereas someone racing downhill, or someone riding their local trails, will be able ride a longer, slacker bike faster because they know all the set up lines and have to make fewer quick adjustments on the fly.

@sebstott I'd be curious on your thoughts about this having tested a lot of long bikes over the years.
  • 5 4
 I'd like to at least see them prove it some amazing thing before dropping 6 to 8k$ on a 38lb bike that's long as a Lincoln. I'm fine with bro science stuff too. I say throw it into the EnduroMag shoot out (give them some extra setup and testing love) and have at it. If the big pro riders were running XXL bikes with an angle set, I'd be more interested...but when we are seeing big pros sizing down (6-6 Jack Mior)...and even little pros (Remy and maybe Jesse). Its not a good look.

 @eblackwell: Moir’s bike last year had under a 460mm reach with the under fork spacer, longer fork, and huge stack of spacers under the bars on large frame!
  • 1 0
 @shepridesbikes: was it 460 as standard or was the 460 measured after the increased stack? Banshees new bikes for example come up fairly short in a large (470), but the increased stack height means this figure is more true to life since you won't necessarily need any spacers.
  • 2 0
 @AlanMck: Pretty sure its a bit under 460 actually. Stock bike is 464 with 170mm fork. Jack's has 180mm fork and about 30mm of spacers. He's probably closer to 453ish I'd guess.
  • 3 0
 @eblackwell: Even the Spectral only has 480mm of reach in a Large (Jack rides a large Strive), plus the stack is lower. After spacers/overforking etc...he'd have nearly the same reach as a size Small G1 I think. Regardless, is the world filled with long straight, steep gnarly trails? I'm a trail builder and we aren't trying to build straight lines through the trees but the opposite.

 @Saidrick: except it doesn't. I've read it more than once by now, and while is certainly interesting, it has some issues:

Someone in a similar discussion here a few weeks ago actually shared a spreadsheet with a good sample of pro riders and frame sizes. It was pretty obvious that they are all over the place.
  • 3 0
 @Arierep: While there are certain exceptions, I think the general trend is towards smaller bikes for EWS racing, or at least a significant subset of the top racers that prefer smaller bikes. For example, if you look at the top 10 at Finale last year, the vast majority are on recommended or smaller than recommended size for their height, (with Jesse shortening his bike over the off season). And for most of the riders, we're talking about frame sizes that are modern but not extreme like the Geometron in this review. Which EWS racers have you found that have size up? I can only think of Greg Callaghan who I think was on an XL Spartan for a while, but I don't know if he raced on it.

The “one trail” they tested on is an actual EWS course AND they took the best 3 out of 5 runs AND their testers are actual EWS racers. Additionally, the article actually names EWS racers and why they run small bikes and handlebars.

 @Saidrick: EWS trails vary widely from eachother and different bikes will shine on different trails. This, testing in a single location is inconclusive.

 Disappointed to see the fork in reality doesn’t work any better than a stock fox item, adjustable offset is cool but only if it fixes a problem you know you have - there are so many adjustments to go through on this bike already.

Looks like the 38 is a better option in any case, cool concept though.

 Why couldn't you just find out what the frame weighs? A key part of this whole review is the weight of the bike - plus you mention that there are many different build specs. Just telling us weight of the one particular spec you ran doesn't really help the reader figure things out.

 The XL frame weights in at 3‘930g without shock. With EXT shock it is 4'750g.

 I got my G1 just under a year ago after discussions with the guys at Geometron then ordered one right after a test ride.
I run it as my only bike, with lighter wheels and tyres for all round use and downhill hoops for the rough. Naturally it’s superb on the rough, steep stuff as expected but the bike amazes me with how good it is at climbing and how comfortable and efficient it is to ride for such a big bike even on everyday use and gravel path rides etc - all the stuff I originally thought it would be crap at. Just my take anyway but would recommend a test ride, Geometron guys are super knowledgeable and offer top notch service.
  • 2 0
 I own an XL G1 and I’m 6.4, over the years I’ve ridden lots of bikes and like many of the comments suggest smaller bikes with less travel are poppy and playful ! However this is all relative to your terrain and the speeds you’re going! I used to live in the South East of England where the trails were all very below average and you needed a small travel short bike to bring life to the trail, popping off things and pulling a manual etc.
Then last year I moved to North Wales right by DYFI bike park! The terrain and speeds up here dissolve bikes with 475 reach and 150 travel . When descending at 40 miles per hour and hitting huge drops and step downs into fast high berms a long travel, long reach stable bike is the choice of weapon .
It’s this reason the other manufacturers are catching up, the trails and bike parks are getting faster and faster . The higher the speed the longer and slacker the bike needs to be, exactly why your MX bike is really big !
The speeds in the sport are much higher now than they used to be .

 I’ve had good luck with sizing down on the Nicolai G15 and G1. Despite their recommendations, a small fits me perfectly fine. Also, I recommend purchasing the frames from Nicolai or Bike-Discount if you don’t want the EXT shock. I’m not a huge fan of the EXT tunes, and have been much happier using a combination of tuned coil and air shocks.

Carbon everything and you can get the bike down to 32lbs, so mine don’t really feel like pigs IMO

 People are so obsessed with weight. That's why people are so obsessed with plastic! I remember years ago trying out a mates Kona Stab Downhill Bike which weighed about 50lbs. I did a downhill run and actually rode the thing back up the hill as a test. I was actually pretty amazed how well a 50lb DH Bike climbed. This thing clearly won't be a problem even though it weights 37lb Stop being so obsessed with weight. It's about the quality of the bike and how it rides that is important Don't forgot... Always buy metal, not plastic, and you won't go wrong.
  • 3 1
 Ever since carbon could save weight, we’ve been conditioned to think grams matter, because lighter carbon parts weigh less. They also make more profit, AND they break more, so bonus, replacement profit!
Does weight matter some? Sure! But does it matter as much as we’ve been conditioned to think it does? Nah, bro. Clearly there are non-weight advantages to carbon, but I’m not so sure that carbon is the pinnacle of frame materials, at least at this point. Agree, it’s much more about ride quality, durability, strength, and flexibility, than it is about saving all the grams. I hate twitchy bikes.

 @erikkellison: Chris Porter once said that we are so obsessed about weight because it is one of the few things we can measure. And I think it is true.

I can't say my XO cranks perform better than my GX cranks.

My G1 one is the best climbing bike I ever had (I can compare it to the Yeti SB150 and 130), despite being 3kg heavier. A set of light wheels and different rubber are enjoyable.

 I believe ghat this thing rides like a beast. But …. when I look around I see tons of awesome designs in animals or plants, strictures of carbon, crystals and many more - everything our nature designs is beautiful and functional.

So diamond bike frames are going to stay forever. If humanity dies and a new species rules the world - a new diamond frame will be invented - just because it is natural and the best way to do it.

This bike is is fun, for sure. But it wasn‘t build to stay forever …

 @sebstott, Thought for the day, have you tried running a high bb configuration to increase agility? You’ve got inherent stability with the long wheelbase and slack head angle. I found playing with BB height made a big difference to the handling allowing you to tailor it to your own preference and riding style. It can make it much more playful if that’s your thing.
I also found the rear of the bike outclassed the 160mm selva r it came with but a custom tuned 180mm 38 was a much better match. I,m running around 25% sag in the rear.
Absolutely love my G1, it’s so comfy on long trail rides as well as being super capable.
I do keep wondering about a 180mm ohlins dh38 though.....
  • 1 0
 What do I know, I’m slow & I like my 66 degree head angle just fine... but..

I really question the ultra-sensitive, custom coil shock, spherical bearings, self-sagging rear suspension ——— mated to an air fork. In my experience, even an ordinary air shock on ordinary bushings makes for rear suspension that feels WAY more active than a matched air fork, because of the inherent added seal drag on the fork, not to mention the telescoping bushings.

 I'd love to see an updated review from Seb after he's decided what rear wheel size he likes and with a fork he knows and likes [that MORC 36 is Pretty specialist stuff] - so he is just testing the frame / suspension package.
Also a test with a more suitable 2.35/2.4 rear tyre to suit the fitted 471 rim rather than a fat bike tyre.
The G1 suits a smaller rear tyre or sure, that's the way MrPorter rides it (with 27.5 x 2.35 rear) and who's to say he is wrong ;~}
Ideally it would be great to know how Seb feels once he has had a bit more time to get used to the bike [in one configuration]. I never cease to be amazed at how testers can switch from their own bike to test bikes and adapt so quickly as to not still favour the one they are used to riding most days.

  • 9 9
 I think there’s more than a few seconds difference in climbing times with this bike, otherwise the author would have posted the times between the Focus Jam and the G1.

To me this bike is for racing enduro or self shuttling dh runs only. And for that purpose, it’s an excellent choice. As a trail bike or for riding around everyday, not so much.
  • 16 3
 I went from a 14kg carbon enduro to a 18kg enduro converted dh bike with geometry similar to the g1 and it climbs slightly slower but more comfortably. If you really care so much about climb times what are you doing looking at a 170+mm travel bike, the new Scott spark seems much better choice for you.
  • 6 0

It’s not so much that I care about the climbing, as the review never really identifies what type of riding this bike is intended for.

New/ uninformed riders reading this review will think this is a regular type of mountain bike. It’s not.
If you ride this bike on regular trails, it will feel like you’re “road biking” on dirt. It will mute the majority of rocks and roots.

If huge gap jumps and crazy steep downhill is your jam, this bike is awesome. However the review tried to paint this bike as a heavier do-it -all bike, which I do not agree with.

P.s. for the record, my 160mm fork bike weighs 30lbs and my 200mm dh bike weighs 1 pound more than the G1.

 Agreed, this bike seems like the ultimate choice for shuttling or bike park days. For general use, it would be too much for my area. Absolutely love the looks and design approach, it's a beautiful bike.

 @Saidrick: I agree that it mutes the trail because it is so capable. It is similar as if you were riding your DH bike on your mellow trails. It also make you go too fast all the time so you approach these mellow corners at a very high speed :-)
I do have a 2nd bike now "for around the house" that is more nimble. But I am still not convinced it was necessary and I miss my G1 every time :-)
  • 5 3
 I have one and have had some other bikes before this one. When you say this is for dh runs only and shuttled it is clear you never climbed with one of these. I do climbs better than ever on the G1. Front wheel stays put on steep hills and the pedal efficiency is the best I have tried. This bike is the best bike I ever had for downhill and for climbing. One thing is all the theories here on the comments, another is riding it ;-)

  • 3 1

I have not ridden one. It’s the exact opposite of what I want in an everyday bike:

I like my wheel bases to be short, my head angles to be closer to 65, super steep seat angles are awful for rolling terrain or flat trail sections and and having crazy amounts of travel makes the trail feel like pavement.

And I don’t like the idea of climbing with a bike that weighs almost as much as my dh bike.

Also, there is no getting around the fact that bikes with wheel bases this long simply will never be good at tight turns or switchbacks.
Your mileage may vary.

 Great review, super exciting bike, dumb paragraph justifying the weight. Just say that it’s supposed to be overbuilt with a lot of flip chips adding weight.
