Great test/review!!! Just finished building up my S-Works Stumpy '15 as well, and I absolutely loved your video-it hit all the right notes for a tech enthusiast like me. I swapped out the stock shock for the Intend Hover Opt, which brought even more suppleness to the rear. I’m no racer anymore (gave that up 20 years ago), but I’m still knee-deep in the tech and love experimenting with setups. The biggest improvement I noticed is the increased traction at the rear. Other than that, the ride quality feels on par with my S-Works Enduro-it’s that same buttery-smooth travel. For the front, I’ve fitted an Intend Flash USD fork with 160mm travel. The result? Insanely plush performance, giving the bike a “magic carpet” feel, all without that bogged-down pedaling sensation. Since my daughter has taken over my Enduro, this Stumpy feels like the perfect “one bike does it all” solution for a 50-year-old who still loves to shred. Absolutely stoked with the setup! Keep up your good work. Subscribed.
Thanks for the comment and sub! Stoked you’re loving the S15 and interesting to hear about how you’ve set it up. We’re doing our off season testing at the moment so will definitely have to look at some more suspension stuff. Is the Hover a coil or air shock?
Love the video, really interesting format and loved the analysis. I have an S-Works Stumpy 15 ive just built up and absolutely love it!! Massive congratulations on your recent result too!! 🎉🤘🏻🤘🏻
It's good to see this kind of feedback from you on such a "moderate" bike! Trail bikes have really gotten so good! Also, lowkey awaiting the public release of the Lyrik Ultimate in Electric Red now that the Zeb is out!!
Congrats on getting into the Specialized EWS team bro. Smash it! Got my Stumpy 15 Expert arriving in a couple of days. Hopefully before the weekend coz it's forecast for sun!
I would think a Vivid with HBO would be better than the Genie. Two separately tuned circuits. I think the Genie is sick, but frankly it just seems like a cheaper, simpler way to get bottom out protection with less weight and complexity than HBO. This will appeal to more Stumpjumper fans than Evo fans. New Enduro will be out soon after enduro season ends and prospective Evo buyers will be enticed by the bigger bike while the Stumpjumper (non-Evo) fans will be glad the bike is this capable with the lighter weight of the Genie. And people who like to use the bike for everything, still can.
Great insight, I prefer the SDLX than the Vivid but that could be a good option for most people. I just really like the supportive mid stroke I get with the SDLX
I think the new Enduro will be enticing for EVO owners that have maxed their EVO out. I'm running mixed wheel, WRP yoke, Cascade link, Medium + shim tune w/ 1.0 spacer, Fox 38 w/ E-Tuned, and 5DEV 155mm cranks. It's definitely capable. I'm hoping Specialized amps up the Enduro with the adjustability and modification/ aftermarket that the EVO has. To me the EVO is Trail/Enduro. Hopefully they make the Enduro to be Enduro/Downhill adjustable.
Loved this format of bike analysis and setup Chuck! Obviously youre going to be a bit biased but i'm sure the new stumpy shreds. Can you notice an obvious difference in the way the new XL (linear) air can rides compared to the standard can? Where do you feel its benefits the most? Last question, might be more for you mechanic, but how intuitive and effective is that new Motion Instruments DAQ system?? Would you recommend it to a weekend warrior who loves to always be searching for optimal setups in their suspension?? Thanks for the sick content and stoked on the season your having! Finish strong my dude!! CHEERS!
I could definetley notice a difference between the XL and the Linear or Progressive Can. XL can felt good but was a bit less supportive on repetitive hits at race pace
Thanks for this comparison! I would be stoked to hear your thoughts about the new Genie shock for this bike. How would you describe the difference between it and the one you are currently riding? Also, I saw some builds with the Vivid shock, which also looks pretty interesting. What do you think about that?
I mean, understand sponsors but without the Fox Custom tuned shock. The test isn't really relatable to the version i would buy. All the hype is around the shock.
Well he likes the linear air can version of his shock, and the speci shock is even more linear than that. He says in the video he can accept the bottom out on the linear because it’s overall smoother. The genie will give the feel he likes without the bottom out! I know this is deduction and not hard data but the concepts are there and I haven’t talked to anyone who has tried the genie and not LOVED it
Hold up. Isnt it just him testing for his future race bike and how it compares to his current race bike. This isn’t a product review for the general public. I mean this is a racers channel not pinkbike
@@LoamMTBSlide haters said that the new stumpy 15 is too linear. That Charlie likes it better means that the frame is still rad with or without genie tech
That was a cool overview. Between very competitive race results and the cool ambassador and general scene content you provide as a fan I’m stoked! I hope Specialized appreciate all the effort too!!! I may have missed it but I assume you are running 160mm fork in the Stumpjumper 15? I’ve always thought a short travel and long travel bike are a good quiver (if not needed) but more and more short travel bikes are getting increasingly capable and long travel bikes more efficient.
Out of curiosity, do you remove a volume spacer(s) from the progressive air can compared to what you have in the linear air can? I found after getting the same sag with higher pressure on the megneg, I had to balance the feel of the larger negative chamber with a larger positive chamber (less positive volume spacers). Might be something to try if you haven't yet
Yep we did sometimes remove a spacer or two from the progressive can but I prefer the linear can anyway as I need the extra mid stroke support that it gives me
Hey there, I'm curious about your bike setup. How much PSI do you run in your front and rear tires? Also, what's your air pressure in the shock and fork? Lastly, what rebound settings do you use? Thanks!
@@ChazmaztvI'm 178cm and sized down this time (s3) for a more playful bike and better on the steep jumps... Running the 40mm but thinking of going to the 50mm. Great review, bike is so much fun.
I would love to know what your settings were while on the progressive air can? Your base settings were very close for me, so also I would like to hear more information on why the linear air can? Also can you put a UHD on the Stumpy 15?
chaz-man how are you!? thanks as always to share yours opinions and feelings on the bike!!! Mate what chainrings do you usually use to train or race? 32t 34t? what about the offset? 6 mm, 3mm...0mm maybe? Do you have problems with chainstay? thank you so much!! CHEERS!
From a racer's perspective, I'm surprised you'd find a preference for the Stumpy 15 vs. the current EVO model, especially if you are not able (because of sponsorship) to use the Genie shock. You're basically "giving away" a little bit of travel, while also running significantly less leverage rate with similar ending rate (2.49) between the two. If you aren't going to use a larger volume shock, you're presumably giving up quite a bit of small/midsize bump sensitivity and traction as the Stumpy 15 has way lower leverage throughout all of travel. The 15 was basically built specifically for that Fox Genie shock, or a large volume shock with HBO.
Very interesting perspective, I thought similar to you when looking at the curves but when I started riding it I was super impressed with the performance under a normal shock and actually preferred the linear air can on the SDLX over both the Vivid and the new XL SDLX can. Don't ask me why just preferred the feeling. Also worth noting my riding style is quite unique so that could be why I'm enjoying the normal SDLX
@@Chazmaztv That's great insight. Do you mind sharing more details about your riding style? I also count my own style as a bit unique, and it helps if I am considering the Stumpy vs. the upcoming new Enduro!
I don't think the Genie is as important as they try and make it. They also sell a version with 160 Ohlins fork and coil shock which I think I might prefer.
@@brian6speed Perhaps, but the new stumpy has a very different leverage ratio curve than what Specialized and lots of other bike companies will engineer into their frames. This was said to be done specifically because the Genie shock was well suited to a much lower leverage ratio for the first 60-70% of travel than most bikes...
Enduro really is more of big mountain or Whistler park bike, too long in 29” setup although somewhat better with mullet link. Much more suitable for flat out straight tracks. SJ evo and I guess new SJ15 are much better bikes in tighter tracks and steep tight dropping corners as they are much more agile, also I am assuming the 29er is generally better rolling and pedaling for most of the enduro circuit so the stumpy is much better suited to this type of racing. Charlie also mentioned he liked the flex characteristics of the small fork in a previous video
@@Tancam17you realize you can buy it frame only right? And mountain bikers rarely leave bikes as built, and have preferences. I’ve owned axs setups and ridden transmission and they’re not all they’re cracked up to be. Heavy, you have to charge them, and shift more slowly than a cable setup. I’ll keep my shimano setup and enjoy thank you very much.
Thanks for that real open and interesting insight
Glad you liked it
I got to give a shout out to the mechanic! If it wasn't for great mechanics, and trail builders we wouldn't get the most fun out of our rides 🤙

he won't test a fox shock when he is sponsored by rockshox.
All the more reason to test the Fox shock if youre sponsored by Rockshox. If the Fox is better just cover it up like they do with tyres

how much noticable difference is in charger 3.1 compared to 3
the 3.1 just gives more range for light and heavy riders.
Awesome to watch the process of a pro testing.
Have you tried ochain on stumpy evo or the new one ?
Haven't ever tried the O-Chain but we've got one in the box we need to test

Yes in a recent video he told us that hes running it with an 160mm fork.
Thanks, glad you liked it! Yep 160mm Fork! Short travel bikes go good
Do you also try the vivid air?
Yep! Tried another time and prefer the feeling of the SDLX
Thank you! Haven’t even watched yet but this is what I want to see!!
Can you call it an Everest if you only ride downhill? 😂 Good video mate thanks for posting.
why not the fox genie shock?
Racing for Rockshox so I use their products!

I’m running 3 tokens in both progressive and linear cans btw
Mate, were you running 150 or 160 out front? Thanks for the vid btw.
What your opinion between the linear and progressive air can ? ( not the XL) ,thanks
Hey there,
I'm curious about your bike setup. How much PSI do you run in your front and rear tires? Also, what's your air pressure in the shock and fork? Lastly, what rebound settings do you use?
Thanks!
would you run this at 150 or 160 on the fork? I weigh 215 lbs and ride black desert terrain.
I run 160mm fork but it will work mint with either
suprised not testing the vivid? i heard they are great ? not great at 150?
What pedals are you running?
Im buliding this bike, they sell that frame. Way cooler than the bronze lol.
Crank length? Seems so low already i cant imagine running in low.
170 but we're testing some 165's!
Hey Charlie, any tuning stuff done to your SDLX to match the new Stumpy kinematics, or just take an off-the-shelf SDLX and go kick ass?
Hey Jacob it's just one of Rockshox stock tunes on our shocks. Tom says it's called LNL tune (Linear Light Damped)
What pedals are you using mate ?
These ones are some prototypes from Look Cycle! They are mint, hopefully getting released to the public soon
What about sizing? stem length and ur height? Why not try the regular genie?
I;m 182cm and riding the S4 frame! Stem length is 50mm. We race on Rockshox so haven't tried the Genie!

You have the Stumpy 15 set up mullet or 29er?
Full 29er
The EVO is full 29 as well?
my first mountain bike was a 1987 Stumpjumper.....
Camera should show the bike and how it moves during the ride, not the top of the helmet
Good idea! will try that next time
tried it pre launch - the genie is sick but the color schemes available are so meh
Why don’t you ride the enduro?
Guessing probably for the same reason he's not using the Genie shock: sponsored by SRAM/RS and they'd want their riders on Transmission.
He did testing last year back to back with sj evo and enduro. There are videos of it.
@@Gnougattenduro is still specialized bike so sponsorship isn't reason.

Could he still..? I mean..? XDd
Like you were going to tell the us the new bike sucks. I'll ride last year's Stumpy. Spesh would not like.
Wouldn't be buying a new model for about 10 secs gain. I just buy it to be obnoxious and flex. HAHAHAHA.
I'll boycott that frame just due to no rear derailleur cable routing.
Why would you put a worse rear derailleur on it? It comes with axs. Don't be stupid

Everyone knows the Evo was the bad boy. The brawler. The mountain crusher. Destroyer of worlds. Now we get “meh”. Sorry Fuel EX is cooler now.
The differences here are poorly communicated.

And this isnt a review. He shares his test session between the old and the new frame. Listen to what he says and look at the numbers.
Thank you @roddas26 !!
Glad you understand, was a pleasure to share an insight into how we test and set up a new bike!
The Evo would have to win downhill. People race Enduro on it. But for trail riding the new one is probably a little more reasonable.
