Possibly new, possibly just a custom paint job, possibly new rockshox stuff about to be revealed?

It could be a new bike; she posted a pic from Allied HQ w/ a frame in the stand that was blacked out but you could see a chainstay pivot and afaik Allied doesn't have a crab-link bike.

My guess is just new paint on a BC40 though...

Couldn’t find if anyone has posted about this since. But looks like a new Allied trail or enduro bike? Given the BC40 is 120mm I’d bet over 160mm. Ridden by Anna Yamagucci (sp?) at Trans Cascadia. I just hope they keep that raw linkage…

Nice find! Poked around a little and found this on the other site:

The new demo has me a little confused. Is the new drivetrain that they are using specifically just to mitigate kickback? I was looking at it wondering if this is going to be a bike designed for those who want to put in an aftermarket gearbox in the future. They just replace the whole… box? Thing?

The old one had a lower pivot, which performed well enough, but it seemed like Specialized were concerned about it being too low down and at risk of being scuffed or bashed on rocks. When they moved the linkage out of the way, it changed the pedalling characteristics a heck of a lot, and not for the better. So either they could have made it with an idler that doesn't let the chain wrap around the chain ring for more than 8 or so teeth, or they go for the 2 chain route. IMO the chain system is a packaging compromise to fit the linkage they want in a way that isn't at risk of breaking on rocks etc.

I think they moved the pivot for performance reasons, not to protect the linkage from rock impacts. A bash guard could cover that and would add ballast very low down.

Those rearmost frame bearings are going to last about 3 seconds. I think i'd take a filing cabinet over this.

You can find photos of Finn dragging the link thru the ground.  It was a pretty clear problem for the race team let alone a bike you intend to sell to the public.  For me the redesign takes it from a bike I’d have zero interest in owning to a bike I simply probably can’t afford.

Since it runs a Lyrik up front, I would guess its probably a 150/160 bike, or maybe one step smaller. Or as the trend is of lately, a bike that can run multiple setups with different links.

From the pits in Lake Placid today (Pit Bits vid coming in a few hours). What looks like dimples on the stanchion of a Boxxer, I'd assume to reduce friction. Forum expert opinion thoughts?

Looks like there are 4 holes in a row on the tube too.


Some sort of air volume adjustment maybe?

Bushes with dimples (to hold lubricant) are quite common, I guess it could work on the other sliding surface. Wonder what it does to the fatigue life of the stanchion?

The holes let oil up to the upper bushing… those are already on current 38 boxxer.


Someone patented the channel around the bushings. 

I’m sure fatigue is been calculated and tested. RS didn’t mess around with fatigue.

Also curious how they’re making the dimples.

SRAM Motive brakes seems to have gotten an update on the hose exit angle:
https://www.sram.com/en/sram/mountain/collections/brakes/brake-collections/heavy-duty-brakes

I was bummed they Motive didn't launch with that, but now it seems fixed. The new versions end with A2 instead of A1, but otherwise seem identical.

That is better. Though I tried and tried to make it work, I never took a bike out of the workstand with the previous routing because it was so ugly.

Totally. It's frustrating because if someone has an issue with the tires, they don't blame the PM at the bike brand, they blame the tires.

New yoshimura finished works finished ee-wings.  $1400.  Way too rich for my blood but I admit they look gorgeous.

Idk what to call that lol. On a bright side because they took the pivots off of the seat tube there is nothing to interfere with dropper insertion. Looks like it should be able to clear 200+mm droppers without an issue. Also couldnt tell from Priority's instagram post but it looks like its mullet as well

it's a $100 upcharge over the base eewing MSRP. i'd be curious how much surface hardness improvement it offers.  my oldest set of eewings is ~6 years now and it has the visual appearance to show it.

I saw a batch of these being assembled in a shop a few weeks ago. They had some stealthy Maxxis tire patches on them. Care to comment? Wink

definitely some benefits, full dropper space plus freedom to put their pivots wherever they need.

I like the shape of the front, but the rear swingarm style isn't the best looking. It would look a lot better with a regular rear triangle, a bit like the production privee bikes have.

Agreed. Im wondering mostly about the stiffness of the rear triangle. Im not a huge fan of the look but at the same time the way it lines up with the top tube makes it not as bad as i thought it would be from the original pics

It’s our new OEM hot patch style, replacing the current white logo version. 

Same great taste 👅
