Looks like the new stumpjumper comp or the base model has a new NX style transmission. No cable to be seen so maybe electronic?

That red one with the Öhlins is so nice. Wonder why they went with trp brakes on it when they spec mavens on some of the other models.

There's a battery in there for sure. Not mechanical.

Had a quick slow mo look at the video, kinda looks like they are playing around with the chamber sizes (oversize negative chamber maybe?) and have another sleeve over the main sleeve to enlarge the positive chamber?

Just found some more photos on Twitter:

DJI are borderline a household name around the globe. If they can channel their technology into efficient motors and lighter battery tech; this could push the whole industry forward.

 

Would be nice to see them partner with a larger brand to gain credibility and integrate into a proven platform.

Man that thing is so nice!

Finally also some details on the Fox Genie shock. Seems like it is basically an automated or rather position-sensitive version of Scott's NUDE technology.

Now, now... don't go and turn on your automated cat feeder because, if we lose power again the cat will go hungry.

Really - there are literally no similarities to Scott's 10yo nude (...eewww) shock other than a red and blue knob.

(.....eeewwww)

Dji's e-system spec is pretty bonkers with highest power to weight (by A LOT), light batteries, fastest charging time...

Good catch! Definitely looks like wireless NX Transmission.

So no more EVO, and just basically speccing different build kits for what you are wanting out of the bike?

The first word that comes to mind is "underwhelming", especially for all the hype leading up to this launch.This is pretty standard trail bike geo, minus the fact that it stil has a sub 77 degree seat angle and the rear center could be considered short for a bike in 2024/25. That said, it's refreshing to see balanced reach with tall stack on a bike in this travel category but that's still nothing earth shattering considering other manufacturers are also starting to do this.

My initial opinion is that they're leaning on the proprietary shock alone to set this bike apart from others in it's category and I'm not sure that's enough to make it better. I'm curious to start reading reviews when they drop.

Doesn't look like this Stumpy has the headset cup from the Evo, which is one of my favorite features. Makes zero noise and it's really nice to put it in full slack for park days, then full steep for trail riding. Proprietary shock and no mullet option unless I go up to the higher end build? Struggling to see why I'd ditch my current gen Evo for this one. WRP + Cascade link have taken care of the bottom out issues and the bike is still not overly progressive. Glad to see no headset cable routing at least.

Isn't that kind of the point of the Stumpjumper though? It's the Toyota Camry (or maybe more appropriately the Tacoma) of mountain bikes. An easy to ride and live with bike that appeals to the fat part of the bell curve.

Looks like there isn't a cable port hole on the drive-side chainstay, even. Wireless-only?

It is pretty incremental/vanilla, but it is interesting that as a 6 footer the suggested sizing really is a choose your own adventure game...S4 for a shorter, 'traily' bike, S5 the pick up meaningful length on both ends and more of a sled... That said, I'd much rather have the S5 chainstay length on the S4 for me as a guy that mostly rides flatter trails, in the woods.

Yes, and I'm one that believes we always need bikes like this Stumpy, the Fuel EX, and other "Tacoma/Camry" bikes for riders who want to simply get on their bike and have it ride well. My point was that it's underwhelming considering all the hype that was built around it. It's still a nice refresh over the old Stumpy and I hope to see how it rides at some point!

Lets leave the Tacoma out of this..Laughing

The SJ EVO was a gamechanger. Adjustable/progressive geo kind of pushed the entire industry in the right direction for the category. It pedals well and wins EDRs. Can you ask for more? (Actually yes - the sidearm was not great and the downtube was prone to cracking, If they kept the same bike but made those two changes I would buy.. I digress).

This Keynote was a ten minute video on a proprietary shock; the geo is also less adjustable and arguably not as good. I'm sure its a great bike for a lot of people. Potentially the right business decision. But for those of us wanting an upgrade for the SJ Evo... its less a Tacoma and more a Camry.

The new stumpy makes me extremely happy...about my current stumpy evo! Nothing about the new stumpy makes me "want" it. Even the side strut on the old evo adds a bit of character compared to the new one...

"Welcome,
We focused on amazing, fascinating ,unbelievable and bikes.

Our new bike is everything you ever wanted with all the things that are good and no bad things.
Here is a person who agrees.
In short, people who want a bike will like it because we made it better.
This is a person.....he is great also.
The things we have improved are better things now.

As a Tacoma-driving, Stumpjumper, AND Stumpjumper EVO owner, I meant no offense! I've had a lot of bikes over the years, but this current pair are my absolute favorites. I got the EVO first and was so impressed I got the standard frame when they were blowing them out last winter. The new Stumpy seems to be a pretty ideal blend of the two. I'd be giving this a hard look if I were in the market to replace my current bikes.

At almost 6’4” the S5 is my preferred trail geo, but the short rear end, wheelbase and usable stack height on the S4 looks really fun.

Regarding the stumpy; wonder if they got the carbon around the BB area to stop exploding. I want one bad if so. 
 

also, if that is actually a axys NX setup I’d bet my worth (not much lol) that we will never see a new mechanical system from sram again. Good thing I like shimano because I’ll never willingly run a battery on my bike.

RE: New Stumpy...

My big takeaway is when the company who arguably has the largest capex budgets in the industry keeps outputting new models that are small evolutions (Epic EVO, new Stumpy, don't forget Jordan beat Finn/Loic on the "old" demo last season), not revolutions, that tells me we've really hit a plateau of technological progression.

This isn't a bad thing, per se, unless you are in the business of selling bikes to bike nerds who used to think they needed the latest/greatest every year. 

FWIW, this has also happened in the moto, snowmobile, ski, road bike etc world, too, to the point where certain people find a vintage of a product they love, and stick with it even as companies keep outputting newer and "better" stuff. Heck, word on the street is GM has gone back to a 2019 40 for similar reasons...

EDIT: The whole Steve Jobs/Apple/Tech Bro "keynote" launching the bike was a bit silly and out of touch. Just my $0.02.

Do we know the stumpy embargo date?

How weird to make a keynote about a bike yet not release any specs info.

The vital tech nerds found an unlisted big S video in addition to other collateral. Its not officially announced yet...and if I was working marketing/advertising I'd be a little stressed at my desk this morning. 

(that said, in reality, "leaking" a product ahead of time is likely a smart way to put a little more frenzy around a product)

My takeaway is that by removing the Evo from the lineup, there’s far less blurred boundaries on what the enduro bike of choice will be when the Enduro bike does come out. I think Specialized is trying to make more of a distinction which segment their bikes play in.
