GeoMetron has teased a new bike on its social media this past weekend with the 140mm S1 Trail.

The S1 has been designed by GeoMetron to run 140mm of travel with adjustable geometry and the ability to run either 29 or 27.5" wheels with no difference in geo. As with past GeoMetron bikes, the frame, links and pivots have been built by Nicolai in Germany to GeoMetron's specifications. There aren't a lot of details at the moment, but GeoMetron says spec and further information will be provided soon.

bigquotesIt's time to introduce the GeoMetron S1: A trail bike designed with 140mm travel, adjustable geometry, and easily configurable with 29" or 27.5" rear wheels. The trail focused geometry boasts comfort and efficiency for a long day in the mountains or short sharp loops at your local trails.

The addition of the S1 to our product line offers a taste of GeoMetron’s core principles to riders who have access to a different array of trails. Frame features have an emphasis on robustness and ease for maintenance, with suitably sized and sealed frame pivot bearings as well as frame features that offer adjustment like no other. Build kit specifications and our standards of one to one set up endow the bikes capabilities to munch over miles and to bring a smile to your face, more information on specs to come.

An S1 will accompany you for many seasons built to survive multiple winters. Frame weight and aesthetic are a product of well-engineered frame design crafted by Nicolai honed over 26 years! Industrial shapes are complimented with refined and optimised machined gussets, links and pivots which are all designed and manufactured in house in Germany. Compromising strength, longevity and adjustability for weight is not in the GeoMetron DNA.—GeoMetron

When it comes to frame sizing GeoMetron will have size options available ranging from Small to XXXLarge. The S1's wheelbase starts at 1246mm on the small to a sizeable 1393mm on the XXXLarge. The head angle sits at 64 degrees although the Small and Medium sizes are slightly steeper at 64.3. Seattube angle is 78.3 apart from sizes Small and Medium which again is steeper at 78.6 degrees. Reach across the frames goes from 460mm on the small to a 515mm Large and a massive 570mm on the XXXLarge. Chainstay length also changes across sizes with Small and Medium measuring at 440mm, then 448mm for Large/XLarge and the two biggest sizes get 454mm and 460mm respectively.

Full details for the new bike are expected to be released at the start of May, we will keep you updated when the bike does officially launch.

 Nothing like being 6'2", looking at a medium, and thinking "that's a bit long for me".
  • 10 9
 490 is my perfect reach. also 6'2". I do have a ridiculous ape index of +5 though, so that likely plays into it. lol

you aren't wrong in that I would never think a Medium of any brand would be the bike I need. currently on a Large Mondraker and that was a big step back from years of riding XL bikes(of similar or shorter reaches).

I have ridden bikes with 500+ reach numbers and past 505 or so, it's just obviously too big. I cannot figure out who a 570 would be for.....Manut Bol?(aging myself with this reference)

 Don't forget the steep seat angle, there were several bikes that I test rode and thought, OMG this is way too long on paper, but once I rode them I was surprised by how comfortable I felt and on some even like they're too short. Seat angle is a huge factor. ...just sayin....
  • 3 1
 Literally came here to make the exact same comment. I am 6'2", and a medium frame would have me too stretched out. My current bike has a reach of 484mm, and even with a short stem it feels a little cumbersome on the climbs.

 @dogdaysunrise: I'm strictly concerned with descents. People use this argument and it's relevant for claiming, but I don't really care about in-seat performance.
  • 3 0
 @dogdaysunrise: Yea, but seat angle (within reason) doesn't impact reach, only where you position your saddle on the rails. If you fit your bike properly, you always end up in the same place relative to the bottom bracket (and therefore relative to the reach figure) because saddle position is all about optimizing your pedal stroke.

 @KJP1230: Absolutely true, doesn't affect reach, it just sounded to me like many are looking at just the reach and then write it off as too long.

 I’m 6’2” and recently setup a bike with 470 reach, which is short by modern standards, and was instantly surprised with how easy and natural it is to weight the front wheel and maintain front wheel traction through turns.
  • 1 3
 Reach has always been a misleading way to measure how big a frame is. You can have a 500mm reach with a 90 deg seat angle which will fit much differently than a 500mm reach with a 45 deg seat angle. Im all for longer front ends, but I always make sure to measure the distance between the middle of seat and the middle of the stem (ETT) to figure out if it fits.

 My height is only 167 cm. My ideal reach is 417mm. The maximum reach I feel comfortable with is 430.
I look at current trends and I am afraid that soon I will not be able to buy a new bike, not because my health does not allow me to ride, but because all manufacturers will go crazy like Nikolai or Mondraker.
Sincerely happy for the tall riders, I sympathize with everyone who is shorter than me. Our time is running out. :-(
  • 3 0
 I feel your pain, but there are still a few brands out there catering for us smaller folk. Zerode do their Taniwha in 420mm reach, and it's even got sensible sized 27.5" wheels but is a proper big trail bike.
  • 3 0
 I'm like 185 cm and it is the same for us.... Instead of large or xl, I'll need to go with a medium soon, which doesn't make any sense! I'll need a 300mm dropper post lol

 @Timo82: i feel this, 183cm here and im already on a 240 oneup. Luckily theres a few brands now calming down on the reach, new megatower is like 475ish, transition & canyon are sensible too
  • 5 1
 Same height as you. 465 reach on a process x medium. Steep loose fast trails in BC. It’s an absolute weapon. Took some getting used to but I’d never consider 417 reach again. Old bikes were way too small. Don’t be afraid of numbers, try new stuff and take the time to get used to it.
  • 1 0
 @sergeizhiest: Reach is one number only and does not define by itself how a bike fits and feels. I'm 163cm on a size small ht with 618mm ETT and 432mm reach and it's great with a 40mm stem and 9degrees sweep on the bars. I have comfortably ridden bikes with up to 450mm reach. In fact I'm waiting delivery of a frame with 440mm reach (Privateer 141). I'm more nervous about the very steep STA and how this will shorten the pedaling position than the long reach.

Now, upwards of 450mm on a small sounds very long indeed, but if there's one thing I've learned is never judge before actually riding the bike. The new Canyon Strive is quite long too.

 @sitkadog: I tried long bikes. I didn't like it, I like something more maneuverable. If you like such long ones - ok, I have nothing against it. But why is my chance to buy the bike that I feel comfortable riding being taken away from me?
  • 1 0
 I rode a XL Banshee Titan last year and yeah it was nice on easy flowy trail but for more technical, steep, rocky trails, I was not comfortable as I used to be on my previous bikes so I've switch for a large frame. Can't wait to ride it!! Big Grin
  • 1 0
 @sergeizhiest: how long did you actually try a bigger bike for? An hour isn’t gonna so it. More like a week, then you’ll never look back. The benefit of being between the wheels rather than hanging off the back let’s you weight the wheels properly and ride way faster. Once you figure out the balance I’d argue that a longer bike is actually more maneuverable because you can weight and unweight the wheels and charge way harder with way more margin for error. The biggest benefits are actually in tech, anything works well on a smooth flow trail.

But if you want to ride little bikes there are tons out there still, norco sight in a small comes to mind as one of many. But at your height that would be like skiing powder on skinny skis from 1996

 So I am 172cm and have no problems riding a medium Geometron G1 with a 495mm reach - every time I read comments here I begin to wonder if it is too big for me and I should get a bike that’s right for my size.

Then I ride it again and realise that I already have.
  • 2 3
 im 11cm taller than you and i happen to ride a friends medium g1, was great for those long downward fireroads but turning or being fun, forget it.

 I'm 180cm and have a large G1 with 515mm of reach. Tried the XL with 535mm of reach and also liked it. Best bike I have ever had for climbing, descending, slow and fast speeds. If it works for you stick with it and don't feel pressured to change because of what others think.

 Bike is so long the front wheel will reach the top of the climb while the rear is on the flats. I have a new bike design idea... Why not a reverse recumbent where you ride face first on your stomach. Getting in attack position just means you are doing a plank. Now that's progressive geo!

 Probably less than you think. I bought an XXL G1 (555mm reach) a few months ago and was surprised to find that the frame was only 0.2lbs heavier than the XL Pole Evolink 158 it replaced (10.9 vs 10.72).

People get too hung up on weight. Geo, kinematics, and quality/durable frame construction are way more important.

 Seems like a marketing gimmick by now. I get that some tall people need longer bikes but the super long trend is dumb. At first longer bikes made sense but we went past the sweet spot and into stupid trend chasing. I've tried so many bikes where I literally could not move around at all and it felt absolutely garbage on steep trails. There are trails I rode 10 years ago on a 2004 Specialized Pitch that were easier to ride on it than on an unnamed new super duper long bike because I could not transfer my weight to the back
  • 10 4
 It's not a gimmick. If you learn to ride more centered then long bikes work just fine. On the plus side they climb better as well. Just size down if you don't want to longer bike.

  • 2 2
 @GZMS: Manuals are a tad harder yes, but once the front end is up it's easier control. Scandi flicks still easy to do. Steering with the rear is even easier you just move your weigh a smidge forward and the backend lightens up. I'd suggest trying one.
  • 1 0
 @SintraFreeride: I think the very long reach bikes( given seated position a comfortable fit) are less good for flat pedal riders, as by default, they ride heels down which pitches hips back, consequently arms can be too stretched out to control and absorb shocks from front end
  • 1 0
 @Murfdog: As a flat pedal rider of a size large Nicolai G1 with 515mm reach and being 180cm/5'11'' I have not felt any of those problems. Heels down does not mean your butt is over the back wheel with arms fully stretched out.

 @Mondbiker: So true‍♂️. Trying to ride long bikes off the back isn't going to work. Bike doesn't turn because you have no weight on the front wheel . It's like skiing!

  • 1 0
 @GZMS: But it's not a barge it just that we have been on bmx sized mtbs for year. It is better at climbing because you have more traction and the front end does lift up. It's better over rough terrain because the bike is more stable. Do you have to ride it in a different way? Yes, of course! Is it for everyone? No. I've ridden both and I'm not going back. Try one, if you don't like it no problem.
  • 1 0
 @Murfdog: There is a slightly different body position yes but the longer reach isn't so long that you can't adapt to it unless of course you are riding a frame which is 3 sizes larger!
  • 1 0
 @SintraFreeride: “better at traction” and “front end does not lift up” are mutually exclusive.. you either load the weight to the front to not lift up, or the rear, for traction, not both
  • 1 0
 @GZMS: Long chainstays and long front end means you are less likely to spin out or have the bike wheelie on steep grades. You don't need to shift forward on your seat or scrunch over the front end. And because of this you are able to clean steeper climbs provided you have the strength/cardio/gears for it.
