Not the big reveal from Specialized marketing I was expecting.
Yea I’d say it’s a slightly different approach to Norco’s in depth reveal of their Prototype DH rig. Reflects poorly maybe on the Big S and their whole racing program which seems pretty F1 ish in general, but cool to see nonetheless.
I don't think there was that much to hide to be honest we all knew, well most of us knew it was a modern version of some Italian bikes such as DM and Ancillotti from the early to mid 90's
I think maybe its more the shock they have been hiding and not the frame, this seems a bit of a set up with the bike being photographed on the edge of the van and inside the van, its not like anyone was hiding it.
Lastly if it is super secret and this is a leak its about time Specialized have something not so great to them, they have been killing other businesses in the MTB world for years!
What i don't understand in the design is that when an upward force is applied, then the seatstay will rotate in the lower pivot and of course it will also rotate in the higher pivot WITHOUT any resistance -> without the shock being compressed.
In other words, the seatstay with the upper link can move freely (to a certain extent), without any compression of the shock.

There would need to be another pivot above that axle on the seatstay for it to move without the chainstay moving.
As they have it, the swingarm(chainstay) and all links are connected.
Obviously the system works. What i am missing is the question, from an engineering's point of view.
If you take a classic horst link and remove the shock, put the bike on a stand and apply upward force with your hands on the wheel, then the seatstay will rotate in the lower seatstay pivot (in a certain extent), without chainstay moving.
This applies here as i imagine it. I am missing something.

New prototype Dual front suspension system on a Specialized Kenevo comp....this combines a Fox 36 single crown 130mm fork with a Girder type link system and a Fox float DPS air shock giving another 55mm of travel for a total of 185mm travel.
EDIT: In answer to peoples asking Why and what does it do.
This suspension system does a few things completely new and different to any other system made to date.
Because it is a dual hybrid of a telefork and a linkage suspension system working together they give the front wheel two different wheelpaths.....the 130mm telefork wheelpath which in this case is set steeper......and the 55mm link suspension wheelpath which gives the wheel a more backwards wheelpath...approx 45 degrees back.
This gives the suspension the ability to handle a much greater variation of trail obstacles and conditions and it introduces a second level of suspension compliance....what the fork cant soak up is then further complianced by the link suspension.
Then there is the ability to seperately tune the telefork and the link air shock to better seperately fine tune small bump compliance and big hit/bottoming control."

Don't see the reasoning.
If you put a fully stiff spring in this specialized system (no compression possible), when the wheel is forced to move upward won't it rotate through the lower seatstay pivot, resulting in the movement of the seatstay only?
Don't see the reasoning.

I’ve drawn some lines to create a triangle that illustrates why it doesn’t move if you were to lockout the shock. The pivot up on the seat tube by the yellow line is fixed. The pivot that is the red circle is effectively fixed when the shock is made rigid. Those two points define the blue line. The green line and yellow line are fixed length. As a result their positions are completely defined in space.
I built a bike with this same pull link back in 2018. The link under the BB takes a beating. Mine acted like a skid plate slider. I will have to take some pics.
Maybe I’ve been mountain biking too long but that Specialized is boring AF. Really what were they hiding? Nothing, absolutely nothing. Hype department has a lot of funding, engineering department maybe not as much.

In other words, the seatstay with the upper link can move freely (to a certain extent), without any compression of the shock.
Any part of the suspension moving in this case would require the links to be very elastic.
As the bikes sits in this picture it's probably overextended and gives a feeling of the upper two links being on the verge of the unstable point (where the rocker can rotate either up or down). In practice (as has been mentioned by others) this is not the issue. Even with the shock removed all is fine and the axle path is fully defined.
This axle path definition is the reasoning I use to define the number of pivots a bike has - how many links can be removed or how many need to be present for the axle path to still be fully defined. That's how you get a single pivot from most of the Commencals up to V5 series (no need for the seatstays and the rocker for the axle path to be defined), how you get a 4-bar from the current and the 'unveiled' Demo, Sender and the new Intense M1 and how you actually get a 6-bar from the V5 Supreme, Yeti's DH bike, etc.

I think the real reason for this is 'it's easier to use an existing fork than machine our own fixed legs'. This setup seems like it would be harder to tune and more unpredictable to ride, because you never know which spring will be compressing, and what the axle path will be doing.
It's very interesting case study. Unfortunately, no big boy of America the Great is courageous enough to do things like this. Still, anyhow it's interesting, it doesn't help to solve the biggest task of front suspension and that is preserving the front center geometry.
Even now that the cat is out of the bag for Specialized, I don't see the shroud going away anytime soon. The bike looks ugly without it and a major headache to clean the mud out of the nooks and crannies.

Ooooh I don't think the finished to market bike will honestly look anything like this.I got a Hunch they are doing what Intense did with that mega rocker bike from last year. This Current mule from specialized is just providing answers for specialized I reckon . At best the chainstay will be what sticks around as it's tuneable flex but there is just no way that linkage is gonna hang out like an old man's nuts on the final design.

He said that he clipped his crank or chainring. That’s why he couldn’t pedal the rest of the track.
I predicted this design several months back

from our g-out project at world champs. always something in the way but you can see how the upper link moves and the chainstay pulling the lower link.
There would need to be another pivot above that axle on the seatstay for it to move without the chainstay moving.

More footage of Loic on the new bike. He also talks about a new cartridge that is sensitive to air pressure change.

With all the tire debate going on, anyone noticed Bruni running Argotal's?
Can't understand why as Specialized have a similar tire that is supposed to be real good.
Yep.
Argotal probably gooder?

If the pushrod sits lower than the chainring (like in the pic with Iles bottoming out) - it`ll get beaten up pretty hard...
can't imagine the final frame comes with it shaped like that?!
