The lack of mech cable routing completely rules it out for me.
Yes, me too. I try to keep my life as simple as possible and remembering to keep my shifters charged is one more responsibility I don't want. I wouldn't be surprised if all high end mtb's are manufactured for wireless in the near future. 😞
That could happen taking the lead from road...
@@LoveMTB @TC-hl1ws For me, the value of wireless does not justify the cost. I can replace my entire XT setup for under $200, and it shifts perfectly.
In the promo video, you can see an alloy frame with a cable derailleur, so it’ll just be exclusive to the alloy model I guess
Bike industry is getting ridiculous!
The 2019 Stumpjumper was one bike to rule all trails and then they split it in two; a short travel trail bike and a borderline enduro bike (the evo). Now they have gone back to what the Stumpjumper always should have been, a mid travel trail bike that can do it all.
The new frame looks better without the side bar but leaving no option for a cable drivetrain is sort of concerning. I’m a SRAM user but went back to X01 after trying AXS for a season.
Yeah the new frame looks great, some say similar to Levo SL. As for AXS, I am using the old X01/XX1 mech🤓
I hope you will continue your channel for a long time. Your video of this new Stumpjumper is better than pretty much every other video out there. And your other videos are just as good. Keep it up!
Thanks, getting harder and harder to justify the effort but my passion for everything cycling gear is intact😉
The EXT Aria isn't quite the same as the Genie. The Aria has two separate positive spring chambers, each with its own valve so you can adjust the pressure in each individually. This allows you to have a sensitive initial/mid stroke while having the ramp up and bottom out resistance at the end stroke. This is similar so I can see why you compared it. The Genie is just one very large air chamber that is split into two sections (the inner air sleeve and the outer air sleeve). Both chambers are pressurised from one valve so setup is easy and they operate together until you reach 70% of travel at which point the outer sleeve is cut off from the system which reduces the overall volume of the air spring and causes an increase in spring rate for the last 30% of travel. Arguably the EXT Aria is a better system (just looking at the specs, I have not ridden either shock) but the Genie will be a lot easier for the average joe to set up. And then if you need to tune the air spring you can use the volume spacers to adjust the way it feels. I kinda wish the air can was a screw off type instead of needing to remove the circlip and then pull the can off forcefully. If it was a screw off type, it would be easier to adjust. So yeah, similar but different. The EXT Aria is also a very expensive shock so not really in the same market.
Great details thanks. I said that the idea is not me the implementation is. And the fact that they use a standard FOX damper simplifies it and keeps the cost down
Thank you , very helpful comparison/review
You’re welcome
I ordered one, exactly the same as the one you have there. I struggled to find videos showing this colour up close so thank you for making this video. I have no qualms with wireless shifting. I will have to get used to charging the battery but given that it can go 20 hours which is probably like 10-15 rides before needing a recharge, I don't think it will be an issue. Can't wait to try that Genie shock. Enduro bump absorption with Stumpjumper pop? Sounds ideal.
You’re welcome and enjoy your new rig!😊 as for the ttype battery keep an eye on it it goes faster than that
TRP is working on wireless drive trains too. They had a wireless 16 speed with a Classified hub at Eurobike, although that was more road/gravel, seem logical they might be also working towards a full E-drive train.
Yeah I saw that. They're all after wireless but I think that's not because of bikes like this, good ol' pedal bikes. It is bnecause of the e-Bikes where even running that cable is a nightmare.
🤯 I want that , love bike Zone too 😏
Hello. Nowadays, would your advice Sram GX or Shimano SLX pour mechanical gearing?
@@adrienlevel I would go Shimano SLX every time 😉
Need a comparison of the "15" vs an Stumpjumper EVO.
Tell me what the benefit of similar spec bike at 130 travel would be, I’m waiting…with same pivots, rear pivot and similar upper rocker arm it will pedal the same. I doubt it will be lower weight, maybe an alloy version makes sense though.
Can you review dartmoor rocbird enduro frame thanks
Greetings from PH
@@jasonpatrickdeleon4701 im afraid I don’t have access to that bike. Cheers from 🇨🇦
Looks great and
Lots of pounds.
I need cable shifting this battery stuff is just getting out of control.
@@XCRiders If they don’t see the future might want to shape it?
electric shifting for Ebikes only, no electronics in acoustic bikes!
@@DaBinChe well not according to Specialized…
About the XS drivetrain, "10-52 cassette on HG driver body" Though the smallest cog that will fit HG driver body was 11 or am I missing something?
You are missing the new design for the SX cassette for the HG freehub😉
@@LoveMTB aha. Thank you. Have to take a look at how they did that👍
No wireless is odd but we all have drills. Otherwise I like all the minor frame features. What did they save by eliminating cabled derailleurs? There's still ports in the head tube. They saved four holes.
There's no more ports, I show in the vid the new vs old head tube 😉
And they did not say anything about why...
@@LoveMTB I mean, they saved a little on the size of the ports, not a big deal. Seems like a corporatist decision. I've drilled my fair share of carbon frames with no down side.
@@trentvlak frame only is 4700 cad + tax I would hesitate a second 😎
Very interesting to see PNW dropper and remote as OEM equipment! PNW makes some amazing components so these are pieces you definitely don't have to upgrade.
Couldn't agree more! I was surprised to see that.
I like seeing this from specialized. I wish Trek would get the memo. You don't need to make your own accessories.
I don't think that you will see a bike to necessarily fill a gap as far as the amount of travel, but I do think that we will see a new Status for a low priced, mechanical drive train, alloy option.. Look at the Chisel compared to the Epic Evo...
You could be right. There's a clearly defined void right now between EVO 8 and Stumpy.
Making it wireless only is not great, plus I think reach adjust headsets are way more useful than angle. Otherwise a pretty bike as expected from Specialized.
Pretty it is, I can attest to that. Feels premium
You can adjust reach with the stem or by moving your seat forward/backward. I think head angle adjustment is great because it means you can set your bike up to be steep and nimble or slack and stable to suit your terrain or riding style. Like imagine you are going to a bike park so you set up your bike to be low and slack and then the next day you are going for a 50km ride with lots of pedalling, so you steepen the head angle, raise up the bottom bracket and firm up the rear shock with some volume spacers and you have an efficient pedaller with responsive steering. It's "one bike to rule all trails".
I don't think I will have a desire to replace my stumpy with this :-). Its heavier, nor cable shifting...Thats basically same weight as Stumpy Evo with less travel. I don't understand the reason of this new model.
I think that in the not too distant future we will have available an aluminum model compatible with mechanical transmission.
That might be the case. But one has to wonder about weight, this is pushing 33 lbs already.
Why not just have a cable hatch on top of the downtube like the Roubaix?
Oh through the headset you mean? Cable tourism??? Still don[t have the connection between front and rear triagle
@@LoveMTB no, if you look at the Roubaix road bike there’s a hatch at the top of the down tube that can be replaced by one with the holes if you’re cables. Instead of having individual holes in the carbon frame. Devinci does the same with its Hatchet model.
@@tinshield I'll check it out!
Lost me at wireless drivetrain. Only.
Is that a trend? We will see...😏
Yes. Even if Shimano releases something, I will still be opting for mechanical XTR or XT for many years.
@@johnnnewmex Hope they continue to make them
What I don't understand about the new sram cassette is that now it's available in 10t on Shimano hg. And how is that freehyb body still produce. So basically we have 4 types of freehubs. What about cheap wheels do they offer upgrade from Shimano hg to microspline or xd? And why is xd still a think. At this point better buy the xdr (road version) especially now with gravel bikes so you can change cassettes. That sram xplr 10-44 it's a good option even for mtb, but only available in xdr. Shimano hg, microspline, xd, xdr, to many options. Hope it's not to long the comment. 🤭
@@artoutlawphoto all good 👍
They can do that because cassette sits further out by about 2.5mm. Shimano should have done that first, not it’s patented to sram for the classic HG freehub
@@LoveMTB i understand. But that means it's only and will only be compatible with t-type, otherwise cassette will touch the hanger
@@artoutlawphoto that is correct, same thing will happen if you try your install the XD driver ttype cassette with a hanger
Wait for alloy😊
Yeah with all that added weight they can then justify the use of the DH oriented Maven brakes 😉
@@LoveMTB ya definitely over kill
Not as nice as the evo. I like the sidearm it looked different than the standard. I went to see this one and it was boring, it looks like the enduro with a fat shock. Id buy the old one if i was in the market.
Not crazy about a specialized only shock. Rest of it looks good though. SWAT box is definitely better.
I like the lever to lock it up for sure.
The Genie shock is based on a Float X and only has 3 non-standard parts (if I remember correctly). They say it is no less serviceable than a standard Fox Float. I think it sounds like a great shock and can't wait to experience it for myself. Enduro bump absorption with Stumpjumper pop. Sounds perfect.
To alienate a major market of mech users to me doesnt seem like the wisest of moves especially when putting cable routing support really does not add much in the way of design and/or production costs. I love electronic shifting but really dont like being forced to using it only. I actually prefer to keep electronics off of my pedal only bikes.
I agree about forcing us on electronics, hence my comment about the extra tube-in-tube that would have been trivial to implement.
I think they aren’t going to make that lower 130 ish bike, there is a market but this 145 bike is fine, why use a lower travel, they have the epic for that.
Well still happy with my custom Mega for 3G rather than those overpriced bikes...
Looks like a Cannondale frame
@@catg9196 😎
Why the bike is not mullet? The trend in their Levo is selling them mullet.
S1 and S2 are, bigger sizes can be mullet. Also Ohlins version is mullet 145/160 from the getgo.
Why does Specialized get so much more attention than Giant?
Giant released the new Trance X yet the Stumpjumper is getting much more attention.
I could not get my hands on one of those...Giant is not providing that key price/ performance differenciation like in the past, they are now expensive like everyone else.
Jesus, cables!!!!!!!!!
There is nothing new here other than a high volume can for the rear shock. Might as well went with a coil. Much better performance, not ripping consumers off.
As for ripping consumers off, this is basically a carbon Status with a more balanced geo from its enduro, freeride brother. The stumpjumper used to be a entry way into more serious mountain biking. Now it's an overpriced over speced ripoff. Hopefully, the future aluminum versions will be much cheaper.
Personally I rather save the money and grab a used Status 160 or 140. Get 80% of the performance and save 6 to 8 grand on top if it.
This bike is a perfect example of what's wrong with the industry and why it's slowly dying.
Because the Stumpy 15 doesn't come with a mechanical drivetrain or a 160mm fork, I'm giving it a big thumbs down. Giving me a mechanical Eagle GX drivetrain and a 160mm Fox 36 fork. The new shock looks interesting.
Buy a used Status 160. 80 to 85% same bike, and performance, not carbon, not wireless, save yourself thousands of dollars. The stumpy 15 is basically 4 year old Status in carbon balanced out from purely downhill oriented riding. While they charge you premium asinine pricing for limited to no new RnD.
This is a perfect example of why the industry is slowly dying. Saw this in paintball in the mid to late 2000s. That industry never fully recovered.
If you're a smart consumer and value your money. Mtb will not be for you in the next 5 to 8 years. The average well speced bike is now averaging 5500 to 6000 US. With this one 9000 USD. These are bikes not cars or motorcycles.
@@PeterCPRail8748better off buying sj evo than the status. can get sj evo frame for $1000.
I Loathe Electronics
id rather buy a Scooter/Motor Cycle than a Bike with electronics
I hear you....
I don’t think there is a void, what’s the point of a 130 ish bike with same weight same stats, it just doesn’t make sense…you are far better off with this 145/160 bike for all around…if you want XC get the epic.
You’re correct but they have a 10 lbs delta between the Epic and Stumpy, 120 to 145 with min 200 mm rotor…
@@LoveMTB well a 130 stumpy will probably be 30lbs or more guaranteed , hardly worth it
@@50whatnomadtravelnursemtb5 You could be right, time will tell.
Bike companies only need 2 Trailbikes. The 120/120mm travel Downcountry bike with the Spur being an excellent example. And the 140-150/160mm All-Mountain bike with the old Stumpy being an excellent example. All mountain bikes that fall in between that travel range are probably obsolete.
@@marksandoval5361 This could be Spesh view on their lineup...
I don't like it.
Interesting that the shock uses spring rate to prevent bottoming compared to Rockshox using a hydraulic bottom out damper . How will Fox control the rebound from the increased air spring rate ?
Dual positive chambe bigger can only working for the first 70% of suspention travel.
@LoveMTB exactly for the last 30% the volume decreases therefore the spring rate increases. This will give a faster rebound over the last 30% travel when the suspension rebounds
@@Andy-co6pn no expert on this but I trust Fox to figure that out 😉
TBH bro, all air springs increase in stiffness along the length of their travel and they all ramp up at the end. So by your logic, all air springs suffer from this problem. Has it been a problem in the past? No. You tune your rebound damping to what feels good for you. You can either tune it for small bump performance or large impact performance but not really both unless you have a high and low speed rebound adjuster. So yeah, it's no more of an issue than any other air shock.
Will an aluminum framed model be available that will take cables ?
Unfortunately I have no idea😞
I saw an aluminum version with "cables" in one of the Specialized marketing videos.
So my guess is probably yes.
@@IIISentorIII interesting to see what cable actuated drivetrain would be on that though…
