Specialized Stumpjumper EVO Kinematics Explained

[@nicrepond9350]

Excellent explanation of important and misunderstood information. More brands should do this. Well done.

[@cavsri]

Excellent video, really informative but also easy to understand. 👍 More bike manufacturers should do this to give some meaning to the numbers they quote on a new bike release.

[@SpecializedUniversity]

Thanks! 👍

[@Soso64bit]

Love my Stumpy EVO! Great video explaining why it feels soo good!

[@iantaylor8190]

Great video/explanation from this guy. Very knowledgeable and putting this into practical terms has been very informative

[@SpecializedUniversity]

Glad it was helpful!

[@Old-Man-MTB]

Made me even more excited for my new bike to arrive!

[@darylblain4710]

The travel needs to be more progressive, i had to put ludicrous pressures in my shock to stop it bottoming out. I eventually just upgraded to a more heavy duty shock, but I think the specialized engineering team should try to sort this out.

[@Officernoob]

Even after max volume spacers?

[@darylblain4710]

@Timjko yeah, the dpx 2 that was in there was at the limit of what was recommended by fox. Easiest thing to do was to buy a bigger shock

[@andrewenglishsc]

@@darylblain4710I'd love to hear from more people on this. I just bought a '22 Evo Pro and while I love it, I'm still struggling to get the Float X to feel right, ESPECIALLY coming from a Nomad with a coil shock. How different lol (but way more playful for sure). At 195 lbs I too find myself running super high pressures to prevent bottom out, really sacrificing any sort of supple feeling from the bike. I'm considering either the cascade link or going with a different rear shock and adding spacers. The Rockshox Vivid seems interesting but expensive.

[@darrensmith9182]

Well done specialized on moving away from fsr this bike is awesome and i carnt wait to buy one ,cheers

[@gravitybass]

Eagerly awaiting an alloy version like the last Stumpy EVO.

[@robsprimallife]

I like it, hope to demo one soon.

[@mudkayak6305]

definately looking at this as my next ride. Questions, going mullet without the link... how much slacker does HTA become, how much lower for the BB, and what do we lose on seat tube angle? Also, regarding styling... it almost appears to me that the downtube just in front of the bottom bracket angles forward lower than horizontal, would prefer some up angle in the shape there as tube moves forward from BB and on up to HT

[@SpecializedUniversity]

Hi! Thanks for your question. I'd not recommend going mullet without the mullet link. If you'd like a lower BB or slacker HT angle, you can use the adjustable geometry!

This is how you should continue marketing your bikes.

[@waterskier91]

I recently bought the carbon comp version. I absolutely love it, but my only issue has been that I’m experiencing way more pedal strikes than I’m used to. I have to figure out the bottom bracket adjustment to get it lifted up a little bit.

[@macribas]

Wow, same here @Kory, did you ever figured that out? I'm on an S6.

[@waterskier91]

@@macribas I did, I am on an S5, I flipped the chip, and it has made a world of difference.

[@macribas]

@@waterskier91 So yours was on the low setting from the factory?

[@waterskier91]

@@macribas yeah, I flipped it to high, and had very very few strikes ever since, and I live in a very rooty region.

[@fast93accord1]

Can you give an example of any advantages to the high/low setting at the rear axle? I’ve only ever ran the high setting, because I’m concerned of pedal strikes on low. However I kinda wanna try low to take advantage of a larger rear triangle to feel it out….

[@RennYYZ]

Thank you for replying, help me a lot

[@richchin5163]

It would nice to see one of these for the 2021 regular Stumpy with the flex stay.

[@Climbingbebop]

Great video, thank you for this explainer! What video is all the rad rider footage from?

[@teephud369]

Great video. Just bought a '22 Levo. Where is all this rowdy riding being filmed in the background? Looks like a rad place.

[@SpecializedUniversity]

Nice! A lot of the '22 Levos kinematics are inspired by this bike! As for the trails, that's a well-kept secret 😉

[@teewuane]

Hey Specialized University! In regards to the front fork on this bike, it comes with a 44mm offset. What are your thoughts on running the 51mm offset? I'd love to hear what your tests revealed, obviously the 44mm is what you ended up with so I'm sure you'd recommend it, but what specifically did it change to have the 51mm offset?

[@jamsnastizz]

I’m going to try an EXT Storia coil on my 2022 evo. Will see how the relatively low progression pairs with the hydraulic bottom out circuit on the Storia. Fingers crossed.

[@SpecializedUniversity]

Let us know how you like it!

[@Chromedome-ss6mg]

What is the rear weight bias? I need this for the spring calculator.

[@SunsPSD1]

Specialized U., what's the effect on the AS of the '21 Evo on AS from changes to the front chainring size? I swapped from a 30t to a 32t and my Evo feels a hair less efficient and also the rear suspension felt a bit different. Please advise.

[@tywitt3351]

Which numbers, if any, are independent of the rest or does a design change to improve one characteristic affect all of the others as well. Thanks

[@theforruner117]

[@harzenduro]

Don't gravity bikes (especially those with a High Pivot Design) actually need to have a rearward axle path? I get it that it takes away a bit of the playfulness (especially doing wheelies etc.) but it actually feels a lot more stable on the downhill and the benefits outweigh the drawbacks by far. I have a Deviate Highlander and am amazed by the downhill performance and it still is playful enough to not be too bored.

[@uwu_demon5494]

They mentioned it. They said that in the first couple CM of travel the axle path is rearward adn it takes inspiration from their gravity bikes, but later in the travel they made the axlepath forward so it feels more playful. On a gravity bike rearward axle path is king, bikes like the commencal supreme, that have basicly no forward axle path, are just super fast over stuff.

I having problem with sizing, can anyone tell me what’s the right size for my height, 172 cm or 68 inches

[@MonsterChuck]

You check their sizing? That would put you on an S3. Size down if you are wanting to be extra nimble and size up if all you want to do is ride down. Careful if you size up to S4 though as it may feel HUGE. I am 5'10" (177.8cm) and I went with the S3. Perfect fit.

Maybe someone can explain how to stop this bike from bottoming out. I have the 2021 SJ EVO LTD and it comes with Rockshox which i love but the rear shock at 25% sag and maxed out at 4.5 tokens and I am still bottoming out hard on G outs

[@colinsandlin8575]

Sounds like your shock is messed up, or your 25% sag isn't correct?

Why you gotta switch it up after two years 😪

Because if they stuck with the same design for more than two years, the cost of manufacturing would go down, which would mean the pricetag would come down and people would start to expect cheaper bikes. They just can't have that!

Then why did the last stumpy design last for 8 years with only small small changes

Well opinions are like wheelie bins, e everyone has one. The colours IMO are crap. But the black frame is awesome

[@bfranco1519]

Agreed! Design and ugly colorway. I guess they do have a black frame tho.

[@thehighground4920]

You’ve got to be joking. Please tell me your joking. The stumpjumper evo is probably one of the nicest bikes I’ve ever seen

[@gweflj]

The kinematics are pretty much perfect IMO. Maybe a little to much AS at sag but I get most people can’t pedal. However, the geo adjustments are next level and I would have probably bought two had it not been for the suboptimal Moto rear hose routing. I’m just not prepared to damage the brake hose after a simple bar during a minor crash which commonly happens without the headtube acting as a strain relief. I’m gutted though. Best effort on the market.
