Specialized Launches Mixed Wheel Size Demo

Jun 9, 2020

Specialized Demo Mullet Press Release

Back before the 2019 World Cup season began, the UCI updated the rule book to allow the use of mixed wheel sizes in mountain bike competition. We'd already had an abundance of 29" downhill bikes, starting in 2017, but some racers chose to stick with 27.5" as the bigger wheels were buzzing their arses or they simply preferred the feel of a 27.5 inch wheel in the rear of the bike.

With the change of the rules, we began to see riders racing the mixed wheel, or mullet, setups to noticeable victories - none more so than Loïc Bruni and his domination of the 2019 season with the World Cup overall and World Championship victories. This was all while Specialized only had a full 29" setup available, leaving fans and avid racers wondering if their mixed wheel Demo would ever see the light of production.

The Demo has been openly developed and tested on the World Cup circuit with immense success in the 2019 season under Loic Bruni.

Today Specialized answer that with the official release of the latest iteration of the Demo platform, allowing not only a mixed wheel size setup but adjustability in the geometry to open the Demo up to even more riding styles and preferences.

The layout remains the same as the Demo 29 that was released back last year with its six-link suspension layout bringing a drastic change in suspension characteristics for the brand. The Demo uses a four-bar system to define the acceleration and braking responses of the bikes, with an additional two links then driving the shock which is mounted low and central in the frame. This layout change, compared to the previous Demo generation, upped the amount of anti-squat and anti-rise considerably. Leverage ratio progression was upped too and all curves are now much straighter lines, promoting predictability in the bike.

Geometry, Sizing & Adjustability
Three sizes are still on offer with Specialized's own naming, S2, S3 and S4, which represent reach numbers of 426mm, 446mm and 466mm respectively in the mixed wheel size setup.

Now the Demo has adjustability via a chip at the Horst pivot. There are three modes, Short, Middle and Long, which Specialized correspond to a certain wheel size setup. Short is dedicated to 27.5" rear wheel and promotes manoeuvrability, Long is dedicated to a 29" rear wheel setup and promotes stability at speed and Middle can accommodate both rear wheel sizes and offers a slightly more stable 27.5" setup or a slightly nimbler 29" setup. The Demo comes as standard with a 29" front wheel and 27.5" rear wheel, following the success that their race team found on this combo, but it's definitely nice to have the options for any combo you want.

Added to this adjustability, Specialized also give geometry numbers for the bike as it comes from the factory with the mixed wheels, a full 29" setup and a full 27.5" setup. All those comparisons are given in the middle setting, apart from the chainstay lengths which show the differences the Horst pivot chip can make.

It might seem like a lot of numbers in the table to get you confused, but it actually opens up a lot of ability for the rider to play around with the bike to make it fit their riding style and terrain. It takes a little time to experiment with all the settings, but nothing ever worth learning came quickly. This can also be a useful tool for the keen racer to adapt their bike to the track and conditions in hand when they're trying to go as fast as possible.

 @phops: in racing, 26inch isn't very attractive as it simply doesn't roll as fast. however, freeride has been making a comeback over the past couple of years. alot of bikes at rampage and fest series are 26inch models because it's easier to trick a 26inch bike. i'm interested to see whether or not 26inch bikes start to get introduced and marketed again as big rigs for jumping/tricking as the trend continues to grow.

anyways, its not about what you ride, it's about how you ride it. as someone who has ridden all wheel sizes, i choose to stick with 26 because i ride bike park and quite frankly 26 wheels are cheap to replace, as are 26inch frames. or maybe i'm just stuck in my ways lol

 @thenotoriousmic: Agree 100% with your numbers. That said, I have a blast on my 27.5 DH bike (my DJ is 26" because it makes sense there). I never cleared Crab Apple hits on my 26", did on my 27.5". Granted most of that can be chalked up to experience riding that line and finally going for it. However, the '26 for life' mantra is just as narrow minded as XC racers making fun of dropper posts and anything over 22lbs/9.9 kilos. Several riders used 27.5 at Rampage and I see guys near me like DJ Brandt back flipping, whipping, shredding better than all of us on 27.5. Racers get paid to go fast, that bike is a race bike. Several manufacturers make non 29" park bikes and even this one can run 27.5 front and rear. If 26" is your thing, endless great used options out there and many DH bikes out there can be modded from 27.5 to 26" . I grew up racing BMX from 87 till about 5 years ago. 20" still has it's place in that world, pure DJ etc. All DJ specific MTB's are still 26". Shred on man

 @thenotoriousmic: i currently ride bmx and it's really hard to transfer from a bmx to a 29er
  • 11 0
 @thenotoriousmic: I got similar numbers also. Both my teenage son/myself still ride 26" DH bikes simply because the bikes are in good shape, don't need replacing (since we do less downhill than previous years), and despite what we are told, we still have fun at the bike parks with them. It's not that I'm opposed to 27.5" wheels (we have them on our trail bikes), but I just don't see spending the $$ to upgrade simply to go a little faster. It's our riding that needs improving, physical stamina, etc. not the bike's wheel size to make either of us faster/better riders.

The problem is you're be lucky to even find a 26" replacement tire at a bike park shop nowadays, so when traveling out of area for bike parks, we have to bring some personal spares.

What I'm always really really confused by when it comes to the average dh rider's need to go faster is the fact that the brake bumps just seem to be getting worse and worse where we ride. Is it simply more riders/less maintenance or are people just coming into things faster requiring more braking? If anything, seems the average DH rider needs to be slowed down rather than sped up when it comes to keeping the annoying brake bumps down.

The real need for speed comes to clearing the big jumps, but again, usually that's just skill and commitment vs. the need for a larger wheel.

I've never gotten to the bottom of a trail (say a 2 minute trail as an example) and said, "man, if I could only have made it 6 seconds faster that run would have been fun".
  • 5 0
 @bman33: there’s nothing wrong with any of the wheel sizes. They all have their strengths and weaknesses. There’s definitely loads of situations where I wouldn’t mind a smaller wheel. 26 inch wheels definitely change direction easier.

@DaFreerider44 it’s even harder to go to a bmx after riding a big 29’er. Lol

@kwcpinkbike

They stopped making 26 inch tyres way to prematurely there’s still a market for them now but they’re super hard to find in decent casings and compounds. Just seems the only marketing angle they have is speed when most of us don’t really care. I personally don’t want a deceptively fast but sluggish feeling OTP race bike. It’s the reason I don’t ride downhill bikes anymore and still have three year old process. Here for a fun time not a long time.

 @bman33: Rocky Mountain Maiden can but that's the frameset. 2017 Kona Stinky 26 I think....?
  • 3 1
 @kwcpinkbike: I was in the same camp for years. I just ride for fun, speed and KOMs don't matter. Then I rode a proper 29er and realized all that speed is coming from being able to absolutely rail corners... and that's as much or more fun than clearing a decent a double. No question the newer geo and larger wheels allow me to ride faster, more aggressively and with a much bigger grin than my previous bikes. I don't do tricks to speak of, surely there's an affect in flickability, but for handling, grip and giggles, wagon wheels totally surprised me.
  • 4 2
 @pourquois-pas: Interesting. I've found that 27.5 and Mullets are faster in corners and that the full 29er is faster where it's ability to carry speed shines - flat ground, undulating terrain, and straight-ish downhills.

27.5s and mullets turn better, end of story. THey may also let the rear suspension function marginally better with the reduced unsprung weight. Nothing wrong with 29s, in most situations they will go the fastest with the least effort. Both sizes are fun in their own right. I'm interested in trying more mullet bikes, especially purpose built mullets. I think they look ridiculous but if they can meld the benefits of both wheel sizes I'll overlook the aesthetics.

 @NotSorry: I don't doubt a 27/29 mullet would improve cornering vs full 29, makes a lot of sense. I've never tried one but think it would be interesting. I was on 26, like @kwcpinkbike and didn't figure the new tech was worth the $ to upgrade. The old steed needed move love than it was worth so I demo'd a bunch of 27.5 and 29ers, totally expecting to find 29er to be too big for me (5'10 and shrinking) but I didn't see an appreciable difference on the negatives but certainly noticed the 29er traction. Faster corners? Hell yeah, sign me up!

I may swap a 27.5 off my wife's bike, shorten the rear end 10mm, lower the bars by a spacer (to keep the same body position?) and see how the Tall Boy behaves. I expect more pedal strikes but it may be fun to try it out.
  • 4 0
 @pourquois-pas: In my experience the 29ers don't have more corner traction. I can lean harder into high speed flat turns on my 27.5s than I can my 29ers and my exit speed is higher on 27.5s. I'm 5'8". The only advantage I experience with 29ers is the ease of keeping them rolling and superior rollover of obstacles. On trail rides and some long DH trails my 29er clocks faster times. If being faster was my only goal I would only ride 29ers. I love slapping S-turns, jumping, manuals, pumping the terrain and just being really active on the bike. Honestly a 26 is even a bit better at some of those things but the 27.5 gives me a little more speed than a 26 with less effort. I love the different attributes of 29ers and 27.5ers for different reasons. I think that's why we are seeing mullets coming to production bikes. Pro riders want to maximize all the attributes of both wheel sizes in one bike. I ride my 27.5 more because I have more fun on it and can't wait to try more mullets to see if they really are the best of both worlds.

If you have a Tallboy 4 I don't think the mullet will work very well. You'll likely throw the geo off too much to make a good comparison, even with the flip chip.

 It's a mullet bike, why would they make a large or extra large?
  • 13 2
 Yep, that's going to be me.
I'm 193cm (6'4'') and yes, I do want a bike with longer reach. Very few companies actually make 29er DH bikes in big sizes, I'm pretty much limited to Commencal and Santa Cruz for my next bike.
What really gets annoying is the extreme Difference between trail and DH bikes. I've recently tested a Norco optic, in XL of course, but with a reach of 510 it has 40mm more than my current DH bike. And its not like my DH is old or small. It's a 2019 bike with the largest frame size, in the largest factory setting. I'll have to invest into a reach adjust headset, and it will still only be about as long as the norco optic in size Large (480).

WHY can nobody have some slight hint of continuity in their bike range ? Since I already mentioned them, just look at norco. The aurum has a max reach of 465, whilst the optic in the same size has 510! How in the world does it make sense for a person of my height to have reach variation by 45 mm between a DH and a Trail?

Another comparisson: Norco's top of the range Race-DH (465) is reach-wise closer to their Dirt Jump (430) than it is to their XC (509), trail (510) or AM (515)

 @Floho: Well, consider riding around in a parking lot on a DH bike and a trail bike. Only the trail bike's reach is set as a compromise for you to ride around on flat ground, inclines and descents.

Pick a DH bike based solely on where your reach should be while descending. The numbers have to be different.

 @Floho: I completely agree with you. It does seem odd to me that enduro bikes are very capable downhill with a longer reach, downhill bikes are only different in some cases by a few degrees, a bit more weight and 40 MM of travel, yet the reach is much smaller on most brands

 Hey Specialized - how about including in the press release that you intend to sell the new rear end to owners of 2019/20 Demo 29’s This bike is still brand new. It would be a complete customer service ball drop to not make the parts all backwards compatible at a very fair price. That should be in the announcement.
  • 5 0
 Considering that right before they produced their first carbon demo a few years back, they built their alloy version to be almost identical as a forethought to compatability of parts, etc...it's a safe assumption this will be cross compatible too.

 They did that, cheap also, with the Enduro for the '17-'18 model. Changed it for '18, but the parts could be interchanged. I imagine that if the parts are interchangeable, you'll probably be able to get them.

 @JSTootell: if they do make all available to owners as a parts order for a reasonable price then cool.

But why not just say that in the launch. It would just make them look like they care about their customer base had they just said ‘all parts will be available to existing Demo 29 owners’.

 So many whiny riders out there. Maybe take a breath and THINK, maybe look at what they've historically done, instead of kicking rocks about info they didn't come out with explicitly, RIGHT NOW. Sheesh. and I'm sure every one of you complaining before the facts are out are going to rush to buy this massively needed parts kit, too. Man.

 From what I can tell, all of the linkages appear to be the same compared to the previous generation Demos. The only differences are the seat stay, chain stay, and horst link flip chip. That being said, I don't know about availability for those components or if the main triangles are the same.

 What were the main pros and cons of s mullet 29er instead of just full on 29er? I'm a tall guy so don't have an issue with wheel buzz usually.
  • 2 0
 @Svinyard: if you're a tall guy it wont be as a big advantage for you unless you want to go bigger frame. But for me as a short guy you got the big wheel rolling up front and the fast acceleration of the smaller rear wheel, especially on the druid with the high single pivot you dont need the big wheel as the suspension is really good on square edge hit. I'm able to keep my 34 chainring on a smaller rear wheel so dont loose any low gear ratio. The geo change on the bike doesnt change the wheelbase shorten the reach by only 5mm, slacken the head angle by half degree and drop the bb by 6mm so it corner so well and so nimble in thigh trails. Might not be good for everyone in every riding scenario but for me on my trails is the best of both world.

 @Svinyard: I think the mullet just corners better. It can roll a tighter line, never oversteers, and it allows you to tighten the line mid-corner a lot more intuitively. Also catching backsides is easier. For me, those are the main benefits. The 29er up front also gives really good grip in turns. The setup allows you to ride over the front and let the rear come through. Really manoeuvrable compared to 29/29, in my experience.

 @jaame: that sounds pretty bad ass. I'm not riding ultra steep gnarly stuff all the time and extra agility sounds like extra fun. Thanks for the rundown!
  • 4 2
 @Svinyard: I won't go back to full 29. It's definitely more agile withh the mullet, and more fun on jump lines too. Full 29 may well be faster over a full run on a chunky line. I haven't timed it, except on Strava. I know which I prefer, and its so easy to do on the Capra 29. Just change the wheel and flip the chip to high. Job done.
  • 1 0
 @Svinyard: you ride way further over the front wheel on a mullet, takes a bit of getting used to, even on steep chutes you don’t hang off the back so you can keep the front wheel weighted and there’s tons more grip. The axle height at the back being lower it feels way more planted. I’m pretty tall at 6’2, recently went mullet and I’ll never go back to full 29

 @DaFreerider44: What makes you think you can't run 27.5 both ends on the Demo in this article? In addition, Transition, Commencal , Pivot, GT, YT, Trek, Intense, Santa Cruz, etc. sitll make brand new DH bikes in 27.5...
  • 2 0
 So, I don’t know jack sht anout DH bikes, but I’m curious about the reach numbers on this bike. They seem shorter than the usual stretched-out enduro/AM geometry. Just curious why the long reach doesn’t seem like a thing in DH bikes.
  • 1 0
 Because you are not seated that long time, you are not pedaling up the hill. DH bikes stand by the rationale of making them easy to move when pointed down, even being 29ers. They care more of having the weight distribution centered for optimum suspension performance, having a super long bike pointed down without the proper bar height, most likely you will be loading a lot more the front suspension. Enduro bikes favors a bike stable and quick on the pedals, even when sitting. XC bikes want to have as most traction as possible going up the hill, having a geo that makes easy to load the front tire.
