    Specialized Goes 650B with Stumpjumper EVO Models

    Today Specialized announced two new 650b (27.5-inch) Stumpjumper EVO models to dealers. The decision to make the move to 650b was based on consumer and retailer demand. 26-inch EVO models will be discontinued going forward, but 29-inch EVO models will still be available. Bikes are expected to be available as early as mid-April. As these leaked catalogue images show, each model will come in two colors.
    Frame Features
    150mm of travel front and rear
    Sealed cartridge bearing pivots
    PF30 bottom bracket
    12x142mm dropouts
    Tapered headtube
    ISCG 05 mounts
    Internal Command Post IR routing (carbon model)
    2015 Stumpjumper FSR Expert Carbon EVO 650b
    The Expert Carbon EVO model features a FACT 9m carbon front triangle and M5 alloy rear triangle. Parts include a RockShox Pike RC fork, FOX Float CTD Factory rear shock with AUTOSAG, Shimano XT brakes, SRAM X01 11-speed drivetrain, 650b Specialized tires, and 650b Specialized 142+ Roval Traverse wheels. MSRP is $6,500.

Size:  21.3 KBSo the question is do you spend the extra $1,500-$2,000 because it says Specialized or go with the upcoming Switchback Unveil7?

    Unveil7 — 29er | 27.5 | Switchback Bikes

    I've got a friend riding the 29'er version, it's been over a year now with no issues whatsoever. I think they even now have a 2 or 3 year warranty.

    Thoughts?

    They should offer a blacked out model like they have this year.

    My bike is now officially extinct. It's still the most fun, best trail bike I've ridden and I'll continue to shred as long as it lasts. See you on the trails.

    Well, this is what I have been waiting on all winter. Those colors are absolutely hideous. Hideous enough for me to let Specialized I'm moving on. Time to pull the trigger on the Troy I believe, as I've waited long enough.

Still,I'm sure this bike has been planned a long time ago and like most of their bikes it will perform flawlessly and competitors once again will have to learn something.

    I'm thinking about a those who dropped some serious cash for Sworks and Expert Enduro 29ers back in september,if the Enduro 27,5 will be released well that is quite a bit irritating..

    I'm surprised about why the top tube hasn't been tweaked "a la Epic 2014" style,more straight and elegant rather than looking like a tube of metal crammed between 2 wheels. We are looking at the same frame from 2012 afterall...

    Yeah I agree. Looks like the same frame, I was expecting an overhaul. I probably wont get a 650b stumpy till the 2nd gen or 3 gen frame.

    I just picked up a new stumpy 26" last week. Would've liked to at least tested one of those out. That's what I get for cheating on my Scott dealer. I got the evo comp model best build for the price so still a win.

    Pretty disapointing, it is just the 29er front tri with a new rear and a lower headset spacer to to adjust geo. Ill wait till till actually take the time to design a proper 650b

    Yeah,

    I got a 2014 (!) Specialized Stumpjumper Carbon Evo FSR Expert 26er (friggin name). And I like it SO much.
    And now it is extinct. I got it last november and have ridden it a ton. Couldn´t imagine a nicer bike.
    And the stealth blacked out look is just fantastic.

    If Specialized still has a blacked out Enduro (whatever wheelsize, I don´t really care) in carbon this fall, I´ll buy one to complement my trail EVO SJ.

    Hanging a 29er front triangle with a fork spacer onto a 650b rear-end doesn´t seem super sophisticated and the HA looks quite steep. But maybe it works?

    Maybe they´ll also release a new 29er 2015 Stumpjumper this fall and irritate all the customers who get this "new" 650b Evo. =)

    wow, that bb is pretty crazy low at 327mm, which is about 12 7/8 inches.
    fill what's empty, empty what's full, and scratch where it itches.

    Wonder if the 27.5 rear end and linkage could be retrofitted to a 26" front triangle?

    They may have used the 29" front triangle to avoid having two separate front triangles to manufacture rather than it being a better fit.

    If it does fit and is available I am sure lots of people would want to upgrade their 26" models.

    In addition to the whacky 68.4* HA, what's going on with the external headset?

    PS Stack seems like awfully high too, significantly taller than even 29er models

    i really want to just order the rear end! i bet it will bolt up to my 26" and be a lot more slack!

    The frame only option has a sweet all black version that looks like my 2013.

    Specialized Goes 650B with Stumpjumper EVO Models

    68.4 degree HA?! That's bunk! I had really high hopes for this bike, oh well. Definitely not "Evo" geometry.

    It is a 29er front triangle. The external h-set is to offset the difference in wheels.

    Surprised the chainstays are 435mm. Was hoping to see a taco deli with 420mm chainstays.

    It does seem steep to me as well but I would not be surprised. The bike is really a 29er with some basic modification like the headset cup to make it work with 650b. It is a stop gap since they were losing a ton of money by being slow to the 650b party. It will take a ground up design around the new wheel size to have optimized geometry.

    The bottom bracket height and head tube angle are about what you would get if you took the 29er front triangle and put a 650b fork on it with that headset cup.

    I have been shopping for a new bike for a couple of weeks and got in the ugly debate about wheel size and after reading a lot the conclusion seems to be 27.5 or 650b would be best suited for my type of riding, so I was glad this new 650b came out.

    I was in the store today looking at apparently the only Evo 650b that my local store will get for a while, and came across the discussion around geometry in this thread which worries me.

    Would anyone be kind enough to explain in plain English what the previous posts around geometry mean (i.e. heatset too steep or bottom bracket too low)? Sorry if noob question. I don't do any races, fun factor is #1 for me, speed and going over big stuff is low in my priorities list, so should I pass and just get a 26 EVO?

    Also, is it me or there is very little clearance for the tires? Wouldn't mud accumulate in that area?

    Thanks!

    Well, if the 2013 Evo becomes a classic, my 2014 Carbon 26" Evo will be a rarity.

    I´ll continue to ride it like mad though.
    I really, really, really love this bike. It rides like a dream, very nimble and light. Yet it is also quite efficient.

    I just put a Schwalbe Rock Razor 2.35 Semislick enduro tire on the rear wheel and the bike just flies now.
    SO much fun.

    The icing is the matte black stealth carbon theme. It just looks so great, too.

    The 2011 SJ FSR 29er Comp alloy I rode before was also very nice, but not nearly as refined and with the big wheels not as much fun (for me, personally). Even faster on long mellow rides though. Quite a bit heavier also.

    I understand the constraints for Specialized. The market is hyped up about 650b like crazy. If the 26ers don´t sell in numbers anymore, you´ve got to do something as a company, Specialized themselves marked their 26" offerings as old fish, yet kept them for those "late dog" customers. But those 26" offerings are incredibly refined and ripe. And some really love the feel.

    I would like to test ride the 650b Stumpjumper before condeming it. I can´t believe that Specialized risked it´s series of really great trailbikes and rushes to market with a scrap project. But I have to say I am slightly irritated so far.

    I´ll not speculate how it rides, as looks and numbers can deceive. But I remember the 2009 29" SJ FSR. Not a bad bike by a long stretch. But there was a reason that the 2010 29er SJ FSR was totally different and also rode a lot better ;-)


    Very curious for a serious 650b Stumpjumper review!

    Hey zarf I would keep that 26er evo you got for a long time even if you go 650b. Thats what I plan on doing.

    Yeah,

    I´ll do that. It is an expensive bike - should be ridden plenty ;-)

    That new Nomad looks like a nice addition as a more burly side-option for the days in the Alps.

    FRIGGIN expensive in Germany though.

    Carbon Specializeds at the Expert levels are almost a steal against the import prices of Santa Cruz bikes over here ;-)

    It looks waaaay to similiar to the 29er frame.
    In my opinion the 26er frame looks the goods.
    The 29er looks a tad re-tard. and 650b looks nearly identical (top tube angle and curve)
    I know its not all about how it looks....and im sure it rides awesome,
    sucks really though as im in the market for an evo and wet my pants a little when the 650b was announced...
    oh well hopefully the enduro 650b looks a bit meaner....?
    and im still set on a 26 now.
    blah blah blah

    Cheers

    You know looking at the profile of the bike I thought that the frame looked an awful lot like the 29er frame myself. Head tube angle and what not. Surely Specialized would not be that lazy though, would they? Typically 650b geo should more closely match 26er geo than 29er.

    Get the 26er Evo then!
    I just returned from a ride and again it is so much fun.
    It's the most dialed bike I ever owned and it's just the perfect blend of nimble, fun, fast, light, yet stable and confidence inspiring.

    Availability of spare parts won't be an issue, as there are so many 26ers still and most of us ride their bikes not more than five years anyway.

    If you look at aftermarket stuff, there's mainly 26 inch still...

    I jumped on the 29er train a bit too early.
    I am sure the next generation 650b bikes will be stellar, just look at the Nomad. But first gen always has irks...

    Again, let me emphasize: I haven't ridden as much and haven't had as much fun as with this 26" bike since November.
    I owned lots of small and big wheeled bikes as I used to work in a bike shop. No bike was as balanced. I might buy a park bike and a cheap single speed at some point, just for fun. But right now, I'm covered ...

    Yes, they are that lazy. It is a 29er front triangle with a new alloy rear.

    That really sucks if that is indeed the case. I would expect more from Specialized than a hastily thrown together conversion, even on a first-gen bike.

    Differences in the bike yes, they altered the geo with the different rear end and the headset cup thingy so the points don't line up but it is a 29er front so they could get it out this year before they lost any more money.

    That geo chart is obviously bogus. You think Spesh would release a 150mm travel trail bike with a 68.5 head angle? C'mon man.

    spesh updated the website and lists the HT angle at 68 degrees. A little disappointing for an "Evo", but I'll wait to ride it before I pass judgement. I have a Pike 160 on my 26" SJ and the headtube angle is about 66.8. Not sure I'd want to go up to 68 just to get slightly bigger wheels.

    The 29 evo has the same head angle. Seems steep, but isn't that "relaxed" a bit by using a fork with a greater offset? Somewhat decreasing the angle effectively? I wonder if there are plans to use 650b forks with similar offset to do the same thing.

    Or, 2015 is just a copout until Spec redesigns the frame properly.

    The geometry chart that I posted earlier is legit. Specialized rounded off 68.4* HA to be 68* for its website. All other numbers are same.

    The number that concerns me the most is the stack height (effective vertical height of the headtube from BB) of 678mm (for a large). It is 3" taller than 26" version (1.5" taller than even the 29" version). That alone would make the bike ride a lot differently (probably not in a good way) IMO.

    I thought the bottom bracket on my Solo was low at 13.1 inches. 12.9 for the Stumpy. Something seems amiss with this 650b release.

    Are Specialized really loosing money by lagging in the 650b department? Seriously what percentage of their global sales are trail bikes, as opposed to Road, City, etc? I wager very low.

    I am just in awe that they scrapped one of the best trail bikes ever designed for this, and soon they will scrap the best all mountain bike ever designed (Sworks Enduro), for a tweak, for little or no tangible benefits. Bike business/silliness is hilarious.

    I got to see the new 650b aluminum version in person yesterday. Was not impressed. It was the black and green color. It just didn't grab me like my black Enduro Comp did when I first saw it. I think the blue would be my preferred color if I was going to get this bike. The dropper post has the outside routing whereas other new Specialized bikes have the internal setup. They also did not go with the Pike which could have been spec'ed if they had ditched the crummy dropper post. I don't think I'll replace my Enduro Comp for the new wheelsize.

    My LBS has two. A medium s-works evo and a large comp evo. Threw my leg over both of them. Kinda spun around the shop floor. Wasn't dialed in for my liking and time on it was brief so I cannot give a final verdict. Felt a lot different than my Santa Cruz Solo.

    There is no S-Works version, only the Expert Carbon or the Comp (aluminum).

    i lined up the stock photos of the alloy 29er and 650b in photoshopusing reference points like the saddle and autosag valve to get the scale right. I can confidently say these frames aren't the same.

    Be careful with pics because they may actually be different frame sizes.

    I am planning to throw all the 26, 650b, 29 geometry values into SolidWorks to evaluate the differences for a common frame size by using a direct overlay of the sketches.

    I just need an hour to put it all together and will post when I get it done.

    Excited to see. You can tell frame on the website by how big that that tube that connects the toptube and seat tube. It's massive on the XL and tiny on the S.

    Yes, but can you clearly tell the difference between M & L in a pic?

    I did some pic comparisons and I am pretty sure there are differences between some of the 26,650b, 29 sizes. So I bailed on that effort in favor of actual geo numbers.

    The 650 looks like a frankenbike to me. 29er front triangle, 26" shock size, 650b rear end.

    - Shows CARBON EVO 29" - LARGE front end

    - Shows both frames attached at the BB center, and the seat tube angle aligned.

    EVO-OVERLAY-REAL-RIDE-POSITION.jpg
    - Shows both frames at ride height from the origin (blue arrows near bottom of frame color labels) vertical up to the BB height as specified.

    Note: The top tube length (hor) is slightly different than specified. I used the reach and stack as primary values to set the head tube position. The bottom bracket is common to all measurement methods.

    The TT differences appear to come from a possible angle differential at the seat tube. It could be a rounding issue, but the numbers are close enough to ignore since I have more faith in the reach and stack values.

    I left out the rear end and wheelbase since the primary discussion is about the main frame. Based on these numbers, the front ends appear different to me.

    Thoughts or other analysis?

    They appear to be somewhat different. I guess the question is how Specialized wanted it to ride/handle. Typically 650b's are designed to feel more like a 26er since most brands are dropping a 26er bike. Maybe they wanted it to feel like a 29er. It kinda felt like that when I swung a leg over one yesterday, but I am used to my Solo so every new bike I get on feels weird.

    I am curious how the 26er would fall into those diagrams. I would say those frame specs are pretty dang close even though there are distinct difference. I bet you the 26er would look pretty different compared to the other two.

    Here is the 26" frame and comparison to the 650B.

    Doesn't seem any closer, in fact it is further in nearly every way.

    I was eyeballing this frame for my rig next year, its looking like a pass, whereas Kona is checking all the right boxes.

    However, it may be on purpose, as it seems most of the replies here are from people who seem like they are looking for a 650B Enduro, and not a Stumpy.

    Well, since they dropped the normal Stumpy 26 last year, I was hoping for a similar design in the 650B. But they seem to think all trail bikes should be 29, but they are making more aggressive (Evo) bikes available in large and small wheel configs for rider preference since they must sell enough to justify the effort of adding them to the line.

    BB heights are very close, so the head tubes are very different as shown in this pic. I am surprised that the apparent head tube height of the 650b (when compared to the others at ride height) is taller than both the 26 & 29.

    I would have expected it somewhere between the two (likely closer to the 26). Maybe they set bar and stem combo to deal with this, but it looks like the 650b will be overly tall on the front, especially when climbing.

    I will try to add the rear, fork & wheelbase to see the entire comparison.

    Discussing this with another engineer, he had a new thought about the spacer. Since the frames appear to be really different, this seems to kill the idea that is was added to cram a 29 frame into the 650b application.

    He thought it could be there to allow switching from the 150mm fork to a 160mm fork. You would remove the spacer during the fork swap and that would maintain the Head Tube Angle, Seat Tube Angle, and BB height.

    I think this idea seems very plausible. Some people like running a longer travel fork vs the rear and this would keep the geo the same (up to the last 10 mill of travel anyway).

    That makes a little sense.

    I personally wish they just made a 650 stumpy with similar geo to the 26" and specced the Evo with a 160 Pike. This bike is now off my short list. Really dig the new Nomad, but that bike is just too aggressive for what I need. Now I'm holding out for the 650 Enduro! Just hope Specialized doesn't screw that one up!

    Bikerumor posted some more info and a few new pics with weights. Their thought as well is the front triangle is in fact different from the 29er

    I was hoping for a 650b regular stumpy as well. My 2010 is aging and I'm not sure I want or need the extra stuff that comes with the Evo versions. I may have to decide soon though as the 26" Evo is the last of the breed.

    Coming back to my original question, why do you guys think Specialized made the stack so high, even taller than 29"?

    So you can switch forks, they did the same thing with the 08-09 Enduro SL. It came with a tall crown race to keep the geo close between a 150 and 160 fork. I love the fact that people freak out and think that a big company like Specialized would rush a bike to market or just use whatever front triangles they had laying around. They have been testing these for years now lol. And as you can see from the geo chart on bike rumor, the geo chart that was floating around is not correct.

    So why not spec a longer fork?

    Or is there a spacer in the fork that can be removed? That would be sweet.

    The bike was designed around a 150mm fork. Fox for example only offers a talas 34 in 160-130. So you can use a normal length race and maintain the same geometry. If they spec a longer fork it would blur too closely with the Enduro line.

    Coming from a 12 comp sj26, will the bottom bracket be a lot lower? I'm seriously considering this bike, but have seen comments about the bottom bracket being crazy low. Is that a real concern?

    I rode a normal 26 sj for a year, then an evo for two years. I didn't have an issue with the low BB. The 650b evo bb height is 327mm, the 26 evo is 335mm.

    FWIW, a major Spesh dealer told me the 29er front triabgle is the same as the 650b.

    I rode the 650b today and loved it. It feels like a scaled down 29er and i mean that in a good way. It pedals a lot more efficent that the 26 or 29 so something was done different. It feels good.I am seriously considering ordering the frame only option along with a 160mm pike. I think you could remove that spacer andrfun the longer fork but keep the Geo as intended.

    On paper it looked like a rushed bike but in person it feels dialed! I tried it back to back with the trance 27.5 and I have to say I like the sj better.

    I picked up my evo link for my stumpy 26er comp today. Saw a stumpy 650b in medium at store. I was gonna test ride it but they didn't have my size xl. Frame is different than a 29er when comparing the 2 side by side. They had a black/blue frame in stock, looked like a sweet bike, however I didn't like the colors. Shop manager said they were lucky to have the stumpys and said his shop wont get more till June or July.

    I would say that the bike also feels like a scaled down 29er. And yes, that doesn't have to be a bad thing. The steer tube seemed super tall and it immediately made me think of how that that would be not so good for uphill switchbacks. That being said, the Stumpjumper application is geared more towards downhill than uphill now, and may be that is what they are wanting to do now.

    My LBS shop said there was a dealer chat with Specialized about the new 650b and Specialized basically admitted the 650b was a 29er front Triangle with a 650b rear, and it was because their 29ers are so "dialed" that they didnt need to change anything. The bottom spacer is basically used to correct the geo for use with the shorter a/c on the 650b fork.

    To me that just means "rush job", and we will probably see a proper 650b when they redesign the Stumpjumper.

    There was a Specialized rep in the store when I looked at the 650b last week. I asked him if the frame was just a 29er frame retro-fitted for 650b and he did not deny it either.

    29 front triangle or not I doubt the bike was "rushed" with all the r&d that they have done.

    Anyone seen a review on this bike yet? I'd love to see an unbiased review about how this bike rides... It seems like there is a lot of speculation that the bike is no good because of a 10mm spacer.

    I think it rides great and looks nice in person, but adding a stupid spacer to get the geo where they want sucks. You can do that to any bike. Why not leave the spacer out and do a 160 fork?

    in the video with matt hunter and kyle norbraten I'm pretty certain you can see both bikes have NOT got the spacer, so maybe running the longer travel fork option.

    Pretty sure in the video Matt is on a Enduro 29 and Norbs is on a Stumpjumper EVO 26.

    Pretty sure in the video Matt is on a Enduro 29 and Norbs is on a Stumpjumper EVO 26.
    How right you are.... I was too dazzled by the blistering riding to notice the actual bikes they were on haha epic facepalm, trying to get all techy couldn't see the forest for the trees!
