Review: 2021 Commencal Supreme DH 29/27 - DH Bike Week

Feb 19, 2021
by Dan Roberts  

Next up in our DH bike group test is the Commencal Supreme DH 29/27.

Watching practice at a DH World Cup in the past couple of years and it’s clear to see there’s a favourite bike out there for the privateer and supported racers. Following the success of the Commencal team and Amaury Pierron the Supreme DH’s popularity blossomed.

Up until 2021 they offered a full 29” version and a full 27” version, and with the onset of mullets they arrived with a bike dedicated to just that.

bigquotesFollowing some of the region's fastest down the Morgins tracks there is such a back-having feeling to the Commencal that honestly caught me by surprise mid-air, as I’d just pulled up off some crazy gap without really giving it a second thought. Dan Roberts

The Supreme's aluminum construction centers around its high single pivot design and the necessary use of an idler.

Construction and Features

The Supreme DH's frame is an all-aluminum affair, something that even extended to the spec of our Team model with not a hint of the c-word material in sight.

The low-slung frame paints a nice silhouette from the side, albeit it with a pretty pregnant belly, with all the weight both visually and actually being quite low. It’s a stout construction too, with lots of the forged or machined parts of the frame having a fair bit of meat on them. From the top though it’s a little slimmer, something that is a bit surprising once you take the whopping downtube fender off. That fender is the full width of the links to protect them from the onslaught of rocks and debris.

Commencal stated that they sought to improve the rear triangle stiffness of the previous generation of Supreme DH, and now the bike has a stouter dropout to help that.

Cable routing is all internal, with a short section on show between the top tube and seat stays. The cable entry on the mainframe also doubles up as the bottom out bumpers. They do a good job of protecting the frame from fork stanchion impacts, but when using the RockShox Boxxer, do reduce the turning circle a bit.

Fork bumpers double up as the cable entry points and there are small notches in the standard 56mm diameter head tube for helping line up angle or reach adjusting headsets.

The dropouts have been re-worked to help up the rear triangle stiffness. They also use a 200mm post mount, although our bike was specced with huge 220mm rotors.

There are notches in the head tube to help with alignment of angled headsets if you fancy playing with the head angle of your Supreme DH.

Most of the rest of the construction of the Supreme is a result of its suspension layout. The high pivot design somewhat forces a certain design and is a reason why a lot of the true high single pivot bikes out there follow a similar DNA. The linkage system is nestled down by the bottom bracket and rotates around a forged part welded to the down tube.

Down in those links, there is a lot of bearing on show for the world, and mud, to see along with an alarming lack of lip to restrain the bearings in their linkages. While it’s not provided a source of any problems, it’s a bit of a small detail that as an engineer had me wincing a little.

The Supreme DH’s idler is a necessity for the design, something that we’ll go into a bit more in the suspension section. But it’s a large and robust design with some good shielding around it to hold it in place, keep it out of harm's way and out the way of your pants.

A wide protector not only shields the down tube but also the links nestled behind it.

There are absolutely buckets of tire clearance on the mullet Supreme. So no worries when the conditions get a bit sticky.

Commencal also does a good job of silencing the chain slap, with ample coverage from the ribbed chain stay and seat stay protectors. Even after a lot of riding, it was commented that the bike still looked in great condition, something also testament to the paint quality. There’s a press-fit bottom bracket and a 200mm post mount brake standard along with 2 out of the three mounts for a chain guide. The high pivot design doesn’t need the top guide and so only needs the bottom two mounts to have a bash guard and lower roller.

Tire clearance is plentiful on the mullet version of the Supreme DH, likely accountable to the long chain stay length, meaning that it should gain less pounds when you're riding in the peanut butter.

Other than that, it’s a pretty simple bike. And that’s not a bad thing. The suspension design drives a lot of the choices and Commencal chose to go with a robust aluminum construction that favoured durability rather than all out gram counting. There’s little left to do when the bike arrives other than set it up and go ride it.

Commencal Supreme DH 29 - 27 Geometry

Geometry & Sizing

What once upon a time used to be one of the shorter reach measurement bike brands out there is now one of the longest, with the lengths of their DH bikes being up there with that of the brand’s trail and enduro bikes that have had maybe more limelight in the longer, lower, slacker treatment of late.

There's a static chainstay length of 457mm, and I say static as at sag our bike grew to 475mm and then at bottom out to 525mm, highlighting one of the quirks of the high pivot design in that quite drastically changing geometry, and tire loading, through travel.

The Supreme's on paper geometry actually turned out to be quite different to what we measured when we 3D scanned it. Head tube length is bang on and chainstay length measured only 1mm longer, but our bike's head angle was much slacker, at 61.2°, and there was a much shorter reach, at 470mm, along with a higher stack height, at 626mm.

BB drop, measured 22mm from a horizontal line back from the 29" front axle, or 10mm from a line directly between the axles. Either way, this gave our bike a 351mm BB height.

Riders of all sizes should be able to enjoy the Supreme DH with its on-paper span in reach measurements being wide. But at 188cm tall the L size felt a comfortable fit.

Suspension Design

As we touched on already, the Supreme DH carries on with the high single pivot design that Commencal is known for and has had success with. That necessity for an idler pivot coming from the drastic growth in chainstay and the detrimental amount of chain stretch that it would create with a more traditional chain path. Routing the chain up close to the main pivot reduces that chain stretch to a minimum while still having considerable amounts of anti-squat.

Drive side shows the idler and chain line positions.

The Supreme DH is actually the least progressive bike that we tested, with a leverage ratio progression amount of 19%. It does however keep the curve up in the high ratios throughout travel resulting in an average ratio of 2.87. There's also a lot more travel in there than Commencal claims, up at 215mm.

Commencal recommend a range of recommended sag measurements for the shock, both in % and mm, ranging from a firm 17% setup, through a neutral 20% to a soft 23% setup, all as a sticker on the frame right next to the shock. While it might scare a lot of people off who securely fixate on sag as the be all and end all for suspension, it’s definitely the right way to go with the Supreme DH and is an appreciated starting point for initial setup.

With a 34-tooth chainring and 18-tooth rear cog, there's 142% anti-squat in the middle of Commencal's recommended sag range. It stays high throughout travel too, dropping to 127% at full travel. That's accompanied by a high anti-rise figure too, 126% at sag and only dropping to 95% at bottom out.

Unlike the Specialized Demo and Canyon Sender, the Supreme DH 29/27 is fixed in travel, and geometry for that matter, meaning it carries on that set up and go theme. Although we have seen many of the team bikes sporting adjustable shock and idler mounts to adjust the anti-squat and leverage ratio.

The Supreme DH 29/27 we tested was the Team model and came specced with a RockShox Boxxer Ultimate fork, SuperDeluxe shock, SRAM GX DH drivetrain with Descendant cranks and Code RSC brakes, with a 220mm rotors front and rear. There’s an e*thirteen chain guide on there too.

DT Swiss provided the wheelset with the FR560 with both 27.5mm internal width rims being set up tubeless with Schwalbe Magic Mary tyres in Super DH casing and Ultra Soft compound. Touchpoints are the Descendant models from Truvativ for the stem, bar and seat post with the saddle being a Fizik offering.

Our size L bike weighed in at 17.1kg or 37.7lbs.

The Supreme DH 29 – 27 Team retails for 5,399 EUR or $4,999 USD, which makes it the least expensive bike out of the four we tested. Granted the drivetrain isn’t full X01 like the others, but that’s about it and the bike was ready to go out of the box just fine with all the spec components.

Bike Setup

The Supreme DH wasn’t the first DH bike to arrive for testing, so the process of figuring out the Boxxer settings was already done. Commencal provided a really good starting point for the air pressures, damper settings and even tire pressure. They even provided a range of settings for some of the variables along with the reminder to measure clicks from fully closed.

The Boxxer was suggested to be between 145 and 155psi with the rebound at 10 clicks, HSC at 3 clicks and LSC at 12 clicks.

The SuperDeluxe was suggested to be between 215 and 225psi with 6 clicks of rebound and 4 to 8 clicks of compression.

Tire pressure was suggested to be 1.65bar front (24.3psi) and 1.75bar (25.7psi) rear.

Set up to the recommended settings, starting at the lower end of the pressure spectrum given, it was a tricky first ride. While I do favour a stiff setup, the recommendations were a touch stiffer than I felt comfortable with and in combination with the fast rebound settings it made it difficult to time the bike when you pushed into it.

Loading the bike on a jump take off, compression, or just before getting the bike off the ground resulted in it springing back before you thought and causing some weird moments from the mismatch in timing between rider and bike.

I tried to continue with this setup, despite knowing that I prefer something a little slower, with the thought that it might need time to acclimatise to this feeling and timing. But it simply didn’t work out and I found myself slowing the rebound down both front and rear to try and bring some chassis composure and timing back.

The shock tune on the SuperDeluxe is, however, a light one and even at fully closed it was still too fast for my liking. Swapping the shock out enabled me to get the rebound in a better window and unleashed a whole new chapter of speed on the Supreme DH.

As it turns out, the settings for the Supreme are informed quite heavily by the elite level race teams, and while I can appreciate that those racers are making it work, I’m not at that skill level or preference. So, it might be worth doing a bit of experimentation with your Supreme DH if you too find the recommended settings a little firm and springy. Still though, hats off to Commencal for actually providing an informed and detailed starting point for the bike.

Commencal Supreme DH 29 - 27 Photo Kifcat Shaperideshoot

With a slightly softer and slower setup front and rear the Commencal started to show its hand, and talk about a single-track mind. Following some of the region;s fastest down the Morgins tracks there is such a back-having feeling to the Commencal that honestly caught me by surprise mid-air as I’d just pulled up off some crazy gap without really giving it a second thought. The ensuing flat landings were met with a memory foam like cushioned landing. The Supreme DH is an absolute butter machine for those kinds of big single impact scenarios.

The combination of the aggressive geometry, progressive suspension and a touch more heft do beckon you to ride it with a bit of aggression in your piloting to extract the best. Honestly, just go and watch some Amaury Pierron videos and channel your inner flying baguette and my God this bike rewards you. While it isn’t a complete runaway freight train if you don’t give it that strength and directness of inputs, it certainly functions at its absolute best if you do. And the bike’s addiction to speed is something that contagiously passes onto the rider. It’s got a touch more brutish character to it, not like a bruiser tank at all, there’s just more positive anger in there that wants to throw caution to the wind.

As with the Demo, the mullet setup does have its advantages in trouser clearance and increased bike maneuverability. If you come into a turn far too hot, it reacts really well to throwing your head at the ground and really flicking the bike round a corner, as opposed to the slightly more high in and lean feel of some of the full 29” bikes on test. If you’re a fan of the full 29” setup then Commencal does have an option to cover that, but it certainly doesn’t make the mullet version unrideable. While the character difference front to back isn’t night and day, it is something worth noting. But did make for some last minute inside shenanigans.

The Supreme DH isn’t much of a bike for slowing down to take in the little side hits on the trail. It’ll quietly remind, in a French accent with a cigarette hanging out of the corner of its mouth, to arrête with this nonsense! It can take in the more sculpted trails just fine, but it would much rather hit them at full chat and hunt for the triples and quads rather than pull any freeride flicks.

The more active suspension feeling of the rear actually plays to the character of the Boxxer and the two end up feeling pretty balanced. We even threw on an Öhlins coil shock for a portion of the test to play around and ended up running a 525lbs spring to keep it all in check on the really bike loading g-force turns that tried to chopper it out. Some of the other models in the Supreme DH range now offer Öhlins as spec, alongside the Fox and RockShox offerings.


The Supreme DH is a pretty easy bike to live with. There are buckets of tire clearance and it generally sheds mud pretty well when conditions are into peanut butter territory.

There are however a few areas to keep an eye on, those aforementioned bearings on show being one and the pivot between the rear triangle and links also being in the firing line and a bit open to the elements.

Commencal Supreme DH 29 - 27 Photo Kifcat Shaperideshoot
There's quite a bit of bearing on show in the linkages, so its good to keep an eye on keeping the area, and them, clean.
Commencal Supreme DH 29 - 27 Photo Kifcat Shaperideshoot
The inevitable tool marks from tucking the shock bolt behind the outer links. Compressing the suspension a bit when you tighten the bolt helps.

But chief of all is the positioning of the links in the way of the shock bolt. While a ball ended hex tool helps, it’s a shock bolt and so needs a fair bit of torque which doesn’t lend itself well to the ball end style. This is a common problem on the Supremes with the tell-tale mark on the linkages. I am nitpicking, but it is a pain to have to either compress or remove one end of the shock to tighten the bolts.

While weight is an important factor in making a great bike, so too is durability, and the Supreme DH definitely had more of a ride hard and put away dirty feel to it, and I wasn't forever checking bolts or maintaining it after riding. Yes, it’s carrying a bit more timber than the other bikes but it does make up for it with a steadfast reliable feel to it.

Technical Report

Commencal Supreme DH 29 - 27 Photo Kifcat Shaperideshoot
A fierce combination.The DT Swiss FR560 wheelset just keep on working no matter how much abuse you give them. The Ultra Soft, DH casing Magic Mary's just need air and you're good to go as fast as you can without a care in the world.

DT Swiss FR560 Wheelset: Another fit and forget product from DT Swiss. That might sound blunt and not very inspirational but the wheelset held its tension throughout the test, ran smoothly and quietly and maintained the tubeless setup despite some fairly hefty dents. It’s a wheelset that just works and matches the steadfast durable feel of the Supreme to a T.

Schwalbe DH Tires: As is a common theme with the Supreme DH, a lot of it is informed from the pointy end of racing. And it’s a good spec choice to see full on DH casing tires and Ultra Soft compounds for the Magic Mary tires. Yes, the compound does wear out a hell of a lot faster, but a bike with this much speed contained in it relishes the delight of a softer rubber and also enables you to take full advantage of the mightily powerful 220mm rotors front and rear.

We had no problems in reliability nor too many of our precious chicken leg watts sapped by the idler pulley on the Supreme.
Commencal Supreme DH 29 - 27 Photo Kifcat Shaperideshoot
A small detail, but a noteworthy one. The well covered and padded saddle on the Supreme was a wise spec choice, given that it will no doubt make contact with you when riding.

Idler Pulley Woes: While the public consensus is that idlers are terrible for efficiency, the reality was that on the Supreme DH the added drag is hardly noticeable. I know it’s a DH bike and isn’t pedalled anywhere as much as a trail and enduro bike, there are a lot of riding spots that need some pedalling to move around the mountain or to get to the trailhead, and on the Commencal it was no more effort than the other bikes on test.

Fizik Saddle: A small point I know, but it’s nice to see Commencal spec a saddle that is particularly well padded around all the edges. With the recent trend of sculpted plastic saddle bases protruding out and almost acting as guillotines, the padded Fizik was much comfier when you inevitably bashed into it while in the wild riding positions you get in on a DH bike.


+ Ferocious speed
+ Flat landing butter machine
+ Least expensive bike on test

- Needs a touch more aggression in the piloting
- Heaviest bike on test
- A couple of design details to keep an eye on

Pinkbike's Take
bigquotesThe Commencal Supreme DH 29/27 is an astoundingly fast bike and channelling your inner Amaury Pierron extracts the absolute best from it. While it needs more aggression in the piloting it’s neither a runaway train if you don’t, nor a diminishing return. There’s a bit of uniqueness to its character but grab it by the horns and the rewards are addictive.

In many of the details of the bike and its character you can see a clear link back to its development at the highest level of racing, with the results over the recent seasons proving that it is a winning package.

It is a bit heavier than the other bikes on test, but there’s an air of ride hard and put away dirty to it, and it does all this for a chuck of cash cheaper than the other DH bikes on test.

 Funny, just goes to show you don't need to make a bike from plastic to be asweome. Good on Commencal for sticking to their guns on avoiding the black stuff but stuff producing some of the best bikes on the market. Keep at it!

 @zyoungson: of course, in my experience the limit is 17-17.5kg. Any more and it starts becoming too heavy. On the light side, 15.5-16 is ok, any less and it is too light. A light wheelset can do wonders even on a heavier bike. Smile

 Having a heavier main triangle and lighter unsprung weight isn't actually a terrible idea. The higher momentum of the heavy parts causes the energy of impacts to go into the suspension instead of rotating the bike forward. I don't care what my bike is made out of honestly, as long as I can afford it and it rolls lol

  • 9 6
 @jaame: Totally agree!!! The fact is a DH bike typically goes through a lot of unintended "get offs" with the bike flipping around hitting stuff and this is not good for carbon. Aluminum is better on impact resistance and being aware of dented areas and how damaged the material is. Carbon fiber is difficult to know and spot damaged areas... I love carbon fiber on XC-AM-Enduro bikes, but not DH bikes...

Honestly anything under 18 is nice. And too lite ends up being less stable and more prone to being blown off line in the air. Mass is sometimes your friend

 For the average rider a bike a little heavier isn't going to make a difference. But at the highest levels of racing, I think a lighter bike is faster. Otherwise, why would the top pros wouldn't be running ti bolts and carbon rims? Probably makes the most difference at the start gate and pedaling sections for them, which isn't a big concern for most riders. This is obviously a fast bike.
  • 7 1
 But whatever you like, but I don’t understand the “carbon-is-evil” mentality.

 @TheR: Agree...I was skeptical on the use of carbon for a DH bike, but now I'm really happy with my light carbon frame, the Supreme is a nice bike though.

 @DoubleCrownAddict: Ti bolts are not about weight, they are about never rusting, not binding (if prep paste is used) and colour matching. Carbon hoops are also not about weight. Look at We Are One: their DH hoop is no lighter than the 'equivalent' aluminium hoop but it will out live the aluminium hoop by a huge factor and also require far less (almost no) time on the truing stand keeping it running straight.

 @leon-forfar: That is just not true. We need to dispel this utter myth that carbon is stronger than metal because it just isn't. In the real world carbon has always been weaker especially for rims, cranks, bars etc. For example Enve wheels. Nearly every review of Enve wheels the reviewer has snapped them. Carbon is not stronger at all.

 Carbon is definitely stronger if done right. The questions have to be is it done right, is it durable in certain applications where stresses are likely to be concentrated in small areas, and are the weight, stiffness and alignment benefits worth the extra costs in terms of financial outlay and potential durability issues.
  • 4 1
 @tavaenga: Haha! You know what’s up. Carbon haters can’t afford carbon. And instead of saying, “You know what? I’m just not in a spot where I can buy carbon everything right now, I’ll make acceptable tradeoffs,” they feel the need to rationalize — carbon’s not strong enough, or it’s bad for the environment, etc.

Or maybe the fact that “plastic” (it’s not plastic, by the way) is every bit as viable a manufacturing material as brittle aluminum causes cognitive dissonance, so they have to double down on their original misconception. Doesn’t matter how many times Danny Macaskill can ride down a staircase on a bare carbon rim, or how many times Santa Cruz can drop weights on their frame or whack it against a curb. Cant be as strong as aluminum.

 @MattP76: “Nearly every review of Enve wheels?” I think that’s a bit of an exaggeration. I think it’s happened on Pinkbike maybe once? Even if you’re right about Enve, they are not the only manufacturers. Haven’t heard much about We Are One cracking, or I9, or Santa Cruz. Hell Santa Cruz did a video with Danny Macaskil riding on a bare rim, and he could barely crack it.

I’m not saying carbon stuff doesn’t break. I’m just saying the preconceptions of it being weak, brittle plastic is way off. It’s every bit as viable a material as aluminum with some real advantages.

 Yeah it's definitely better. For me the question is more about value than strength. No way in hell I am ever going to spend 2000 pounds on a set of wheels that are literally going to get smashed into rocks on the regular. It doesn't matter to me what they're made of. My carbon road bike is spot on and I can see the benefits of the material in that application. I can see the benefits on a mountain bike frame too. It's just that it's not really worth the extra in my experience. I've seen these swimming goggles that cost a hundred squids and they guarantee to save you 0.2% over a 100m swim... but I can get some normal goggles for 30 that are just as good from my perspective. So while carbon is great and everything, it's not the be all and end all.

Carbon frames are decent value for money. It's a difficult thing to make in many parts, a lot of bearings have to be in alignment. It has to hold the bottom bracket and wheel. It has to have the correct tolerance to hold the headset cups and seat post. A lot of work goes into frames. Rims on the other hand are an absolute rip-off in my opinion. A hoop of carbon. It must be the easiest thing to lay up and form. I would love to know the markup on a set of carbon rims and wheels. People can talk about R&D cost but I'm not buying it. On a frame fair enough, there are a lot of variables, but a rim is a hoop of material in which 50% of the dimensions are set before any of the designing even happens. Its a single shape of set diameter It has holes drilled into it the same as an alloy rim (they don't even bother to form the spoke holes anymore). Spokes are exactly the same as they have been for at least 30 years and they still cost about the same. A hub is two metal tubes with two bearings and maybe a freewheel. No one's reinventing the wheel. Total rip-off. It's no wonder everyone is selling carbon wheels. It's a licence to print money.

They are not, and will never be worth 2k a set.

 @MattP76: Depends upon how you use carbon. The original carbon V 10 proved to be the strongest bike Santa Cruz ever built. They couldn't break it on the testing machines until after they started smashing dents in it with baseball bats. If manufactures made carbon frames the same weight as metal frames and had good construction they would undoubtedly be stronger. But the focus on using carbon is nearly always to make things lighter. So that's where your myth comes from.

 @TheR: I know plenty of people who've broken reserve 30 rims. All it takes is an asymmetrical rock strike on one sidewall and not the other. Skeptical cause Macaskill hit everything squared up as he had to w/ no tire.

No cognitive dissonance I know of (see what I did there). Have 2 bikes w/ AXS, and carbon everything on the XC bike, even raced carbon BMX bikes in vet, but the trail/enduro rig is running 471's not cause money, but cause risking a broken rim from an experimental line in the middle of nowhere means a 2-3hour hike back to the car (or a DNF in a race I dropped $500+ to attend for the weekend).

Strength all depends on the mfg process, design, and environment.

Its definitely more likely to be ocean garbage than alloy, which can be recycled (not that it always is).

Then your paying 2-5x the price of an alloy equivalent, but whats the ROI?

 @DoubleCrownAddict: Sorry I disagree with that. If you take a steel Cotic frame for example. If you made a carbon frame with exactly the same size tubes as the steel bike it would snap in no time. Thats why they make carbon bikes thicker otherwise they just wouldn't have the strength.
The other absolute pearler is that if you over tighten bolts on a carbon bar it snaps!! If carbon was stronger it should not matter if you over tighten bolts! It's ridiculous

 @Grosey: My buddy was running 471’s and tacoed them in the middle of nowhere having to hike out. He’s been on the same carbon hoops for 2 years now with zero issues, so for him it’s carbon from now on. Another buddy cracked a carbon rim (was WAO with lifetime warranty) and he had no issues riding it out of the trail since sealant mostly filled the crack. Then he got a new rim for free where he would have had to buy another alu. For some carbon is totally worth it. Even in this review the DT rim suffered some big dents so prob has to be replaced soon. Would have been interesting to see if a carbon rim would have come out unscathed.

 @dualcrownscottspark: Problem with women is that they are not gear-centric. They mostly care about colour and looks, that's it. They can ride any bike you get them which looks good to them and rather prefer cheaper ones (because you know, it is better to have some money left for nice clothes and beauty treatment). So it would be hard to borrow bike from your wife even if it would be your size.
And I know because I have a wife who rides with me. It's super cool, but I am sure I would never convince her to buy a bike I want. She finds 90% of good bikes ugly Wink

 Dear Pinkbike Staff,

Last year I made you a wish and, even though you promised me to fulfill it, you still have not, so I come here to beg you again. Could you please include videos in the bike reviews? And I do not mean videos showing shiny parts or the staffs pretty faces. I mean videos showing the action, the bike being ridden through gaps, drops, berms, jumps. And, if possible, not in slo-mo. It does not need to be an overly edited video, but at least show us something. The DH week is almost over and we have not seen an bike being tested going down the hill.

It would be so cool to see people (Mikes, Dan and others) we hear from pretty much everyday showing their skills and riding the bikes I won't be able to buy in a close future (just like Top Gear, my friend).

Sincerely yours,

Also, I always assumed the travel was off because I've rode 200mm plenty of times and it never felt as cush as this and I am riding the 29/29. The HPP is definitely a factor, but still, it feels like so much more.

 @DanRoberts : "The Supreme's on paper geometry actually turned out to be quite different to what we measured when we 3D scanned it. Head tube length is bang on and chainstay length measured only 1mm longer, but our bike's head angle was much slacker, at 61.2°, and there was a much shorter reach, at 470mm, along with a higher stack height, at 626 mm."

Stack off by 6 mm, reach by 10 mm, HA by 1,3 degree. That's quite a bit more than normal production tolerances (assuming the 3D scan is withing say +1 1 mm accuracy). Furthermore, the change in stack and reach cannot be explained by "just setting up the HA jig a bit too slack."

I assume you contacted Commencal about this? What was their reaction?

Cheers, Lars
  • 22 0
 There is a lot of stuff going on here that could be outside manf. issues. Shorter/reach higher stack and slacker HA point to front/rear end height changes. Some quick geo math shows that raising the fork 15mm in the crowns and running a 10mm smaller diameter rear tire than spec (which is not an enormous difference and I would not be surprised if the bike was designed around an Assegai/Minion 2.5 diameter and not Schwalbes) would result in -9mm reach, -.8deg HA, and +6.5mm of stack. Additionally there would only be ~1mm of BB height difference.

That still leaves ~.5deg of head angle slackening unaccounted for. +/-.5deg is a not unheard of for alloy tolerances but also isn't amazing. I am wondering if there is a little bit of number fudging going on in the geo chart with the mullet conversion. In most cases even bikes that have flip chip adjustments for mullet mode would end up with about a half a degree of HA/STA slackening in the mullet config after correcting the BB drop.

As an aside measuring BB drop from horizontal front axle makes no sense. BB drop on a mullet should either be horizontal from rear axle (which is much closer to your feet), or distance from the wheel center line.

Are you absolutely certain that sag recommendation isn't supposed to read 17-23mm. This would work out at bang on 25-30% sag which is a hell of a conicidence, that being the industry standard recommended range. Also means their suggested compression and rebound settings would work a lot better by the sounds of it.
  • 6 1
 Absolutely certain. I was initially surprised on the recommended sag range. We've got a shot of the setting sticker on the frame in the comparison video. Sorry, didn't manage to grab a still of it.

Also, 25 - 30% of a 75mm stroke shock is 18.8 - 22.5mm.

 @dan-roberts: There's a bike check w/Bruni from last year where he says he runs sag between 18-22% (not mm) depending on track/conditions. That surprised me at first. But with WC speeds + coil suspension, it sounds bout right. I generally run 5% less sag w/coil, but for my skills and speed that's closer to ~25%. Endlessly interesting stuff. Anyway, DH week has been awesome and the level of detail in these reviews has made me excited to dig into each one.

 @gemma8788: Interesting for sure. I certainly depends on the individual bike, but I generally start off with 25% sag on a bike and go from there. But also not afraid to be going firmer, and so less sag, if the bike or terrain needs it.

Thanks very much! There's a couple more articles coming too.

 I will answer as an owner of a Supreme and having tried a Furious before this. Personally I think it is great in the air and very easy to launch, but it isn't a jibber. Small side hits and little kickers in flow runs it gobbles up and it takes an actual effort to get it in the air. If you don't, then it just soaks them up like they were nothing- that is the HPP. Making it want to be glued and fast. Gaps, tabletops, and size drop are what it wants and honestly it makes you feel more confident than you might normally because it is almost too easy. Basically, it is a big feature bike. The Furious was much easier to pop around and really felt more like a park bike that you could take downhill. But taking the DH course that is rooted out and not groomed showed the differences a lot. For sure the Furious had no issues, but did bounce around and needed more input to keep on track. A lot of people like this feel, including my friend who decided to go the Furious route. The Supreme will literally feel like a it didn't even know the obstacles were there and soak them up. If you are just cruising, you might actually think the Supreme is boring because it is doing all the work. I think this is what they refer to when they say you need to go full throttle and pin it into everything to get the most out of it. I haven't come close to that limit- wherever that may be. Hope that helps.

 Hey @dan-roberts with the above mentioned discrepancies in advertised geometry (slacker head angle, lower bb) and generous rear wheel clearance, do you envision running a 29’’ rear wheel on this particular frame being an issue? I am looking at purchasing an XL and would prefer the longer chain stay of this particular model (456mm compared to 430mm on the 29er) but wouldn’t mind trying it with two 29’’ wheels.

 Yes, for the simple fact that with a 29" rear wheel in the mullet frame the BB will be sky high. It's already at 351mm!

 One of the fastest downhill bikes around right now and it's got numbers that totally contradict conventional "wisdom" about geometry. super long chainstays and relatively quite low leverage ratio progression. so much smoke being blown by the short chainstay high progression hardliners.

"static chainstay length of 457mm, and I say static as at sag our bike grew to 475mm and then at bottom out to 525mm"

 Well, crap. I have a Supreme and been reading these reviews hoping to find out why I'm still slow..
Truly, though, with a well set up coil these bikes are butter over the gnar and landings off everything I'm willing to huck are just too easy to believe. You trade a bit of playfulness for stability and confidence but it eliminates any excuse for "not enough bike"

  • 4 2
 I've ridden both last year's Demo and last year's Supreme. In my amateur estimation they both ride really well, but quite differently.

For a super fast wide open run, I would choose the Demo--it just has a super stable feeling to it, like a monster truck. It feels incredibly planted in a high speed corner, but somewhat sluggish in a slower speed, technical sections. I think the Supreme has a more lively and flickable feeling about it--the bike just feels more active somehow, to me (I suppose that's the high pivot feeling?) Basically, if I had to choose ONE, it would be the Supreme. I had more fun on that bike in my short time on it.

 Depends on what you prefer to do on your DH bike. If you like to slash around, hit some jump trails, ride some steeps stuff, kind of a bit of everything, then the Demo is a good companion. If you just want to go real damn fast all day long, absolutely monster down steep and rough tracks, hunt for tripples and quads on those jump trails. Then maybe the Supreme might be more up your street.

 @dan-roberts - really interested in those Nukeproof riding trousers you've been using in the recent reviews. Are those just the standard/current 'Blackline Trail Pants'? They look a fair bit slimmer/tighter than in the NP marketing material I've seen (in a good way, I hate baggy riding trousers...), and I'd be curious to know if you've altered them at all and what size you're running to get that fit if you'd be happy to say? Also, is there a review incoming, or are these just your personal preference? Thanks!

 They are the Blackline's. All bog standard too. Really like them, fit and funtion is superb. Currently just riding them as I like them a lot!

 Looks like Commencal uses the exact same frame for their mullets as they do their regular 29/29" setup. This would explain the extra slack HA and the mad rear wheel clearance (almost as if it were enough for a bigger wheel! haha) but I could be wrong, they could have 2 frames. Awesome bike
  • 5 0
 The chainstay lengths are pretty different between the two bikes. They might be using some similar frame parts, like tubing and forgings, but I think they're different beasts.

 the internal rim widths for the commencal and canyon are both 27.5mm and 28mm for the specialized. since DH tires pretty much seem to be 2.4+ and wider, why aren't DH rigs coming with wider rims from the factory? i can't imagine a higher volume tire would be a bad idea for bikes designed to smash the roughest trails at the fastest speeds
  • 1 0
 @Dan Roberts: I would be curious to know how all of these rigs do the one thing that sucks on a DH bike. That thing is trying to sprint fast across a big section of chunky rocks and roots on shallow ground.

Most DH bikes will suck at it and the only ones I've ever truly loved did that surprisingly well. Those 2 bikes were an Iron Horse Sunday and the last gen Turner DHR.

 I'm super excited for this bike. Commencal (and Forbidden) are the only companies I can think of that don't make their mullet options be ridden in a shorter CS position. With Commencal taking it to whole other level by making it a dedicated platform and still selling a full 29 and 27.5 option as well!

I've been wanting to try a 29/27 DH setup for a while but didn't want to run the bike in a shorter setting to make that happen.
This to me seems the best of both worlds - The smaller rear wheel with cut a tighter line in a corner if you want it too but the long Geo will preserve many of the stability benefits of the full 29 setup.

Plus with the super rearward axle path I'm sure you won't get any of the 'smaller wheel meets square edge bump hang up' that more conventional suspension designs can have in mullet mode.

I can't wait to ride one

 Id love to see a review of the new Commencal Furious. With the rear suspension pivot point adjustment, im really curious how it handles the rock gardens. As much as I love the Supreme, the price, weight, and simplicity of the Furious is very compelling.

 I would love to try one of these for longer than I have currently.
Totally underwhelmed by its performance (times showed that too being significantly slower). Might have been setup differences between my bikes and the Commy.

 its fair to say commencal have probably become the most desirable bikes on the mtb market both for the epic performance, reasonable prices and killer looks. Plus they sponsor a whole lot of people

Big thanks for the very detailed Review. I hope there is more coming soon from you Smile The mechanical point of view is very interesting.

Any chance to give an insight of the commencal furious? Maybe you´ve ridden it? I really would like to read some tests of the more affordable (and not race orientied) bunch of downhillbikes.

I´m keen to know, if the furious suspension-layout is really "poppy" and "bike-park-suited" or if that´s some claim due to a not so well working suspension platform.

...maybe there are some riders out there, that already ridden the commencal furious 2020/2021...

 @danroberts. “recommended sag measurements for the shock, both in % and mm, ranging from a firm 17% setup, through a neutral 20% to a soft 23% setup”

Is the recommended sag really 23%

Why not 30-33 like a normal dh bike?
  • 1 0
 Yeah, it really is that. I think Commencal know they need a lot of spring in their setup from the kinematic, axle path and that their recommendations are informed quite heavily from their racers.

 Hey, to any owners or anyone who has ridden this bike before, I need some advice. I am fairly short (5'6/1.67m) and conflicted over sizing. I'm deciding between two sizes, the small and medium. The small's wheelbase looks pretty good to me but I'm unsure of the reach (although I could extend that with a +10mm headset). The medium's wheelbase looks insane at 1290mm (I'm assuming that's intentional though), but the reach looks nice. So, what should I do? As for my riding style and what I'll be doing, hopefully as many races as I can get to this year and a lot of the time spent in the bike park. @dan-roberts
  • 1 0
 Maybe don’t pick between bikes using wheelbase as the first metric. There’s a lot of things that go into the distance between the two axles. Unless you’re worried about it fitting on the shuttle?!

If the reach of the medium is a bit more to your liking then maybe that’s the one to go for. There’s also the ability to adjust the reach with an offset headset. The 56mm diameter head tube is a pretty standard size with there being a few options of reach adjust headset available.

 These DH reviews are a million times better than the trail and enduro ones they posted a few weeks back, maybe pinkbike should send @mikelevy and Kazimer to engineering school so they can produce better reviews...

 If Commencal would ditch the pressfit BB in general on their bikes, it would be almost unbeatable in value for the money. IMO.
  • 3 0
 Last time I looked at some allmountain/enduro bikes, Commencal was around 20-30% more expensive than YT and Canyon. Pretty much on the same level as Trek, Specialized and similar brands. They were never the best value for money, not even close.

But their bikes are damn sexy, so I would be willing to let that slide.

 A more simple language would be much appreciated!

 The reason the geo is different than the spec sheet is because it’s just the regular 29 frame. I have a 29 and friend has a mullet and they’re identical in every aspect.

 Why is it that all the good bikes have to be so expensive? Why can't someone make good-looking, high-quality bikes for less than $3,000?

 @dan-roberts: So you fit comfortably on supreme but with only a few mm longer reach than s4 demo? Could this be the longer chainstay of the supreme or demo's saddle being very forward that made you felt cramped when sitting?

 why the diference of price between usa and europe??
  • 3 0
 Because prices given for US are always without VAT, since VAT varies from state to state. To make this even more annoying, if you go to any shop or restaurant in the US and buy something, the sticker price never has VAT factored in so you get hit with that once you pay for the goods.
