It’s not THAT high is it? Looks similar to a Norco Shore or GT DH bike. I suspect it’s a Horst link, can kinda see a pivot on the chainstay?

What surprises me most is that Yeti would go with this design? They have their 6bar e-bike platform and their switch infinity designs, so why not stay with the brand identity instead of following the mainstream?

Maybe because it is too complicated/unneeded to actually function well on a dh bike? I mean it works relatively well on their trail bikes (which cater to a bigger demographic, marketing wise, than a world cup racer) and such but is it needed on a dh bike when way simpler designs have won countless more races?

What is this business behind the chainring? I know some high pivots also use a second pulley attached to the bashguard, like the e13 guard on Forbidden's, but this is huge.

Less losses Tongue

The pivot looks a bit higher than what GT and Trek use (which is a low-high-pivot (lol...)) but I'd say still lower than what Norco and V4 Supreme use, let alone what Zerode did back in the day.

Do I spy two shock mounting positions near the BB?

Also, regarding horst link... There's a massive aluminium piece concentric to the rear axle. I vote split pivot. As for 6-bar and all, it's surprising to me how small the rocker link is considering it's a long travel bike...

The rocker size looks just like an Atherton, maybe even bigger.

Also, is it just me or is the upper part more like a pulley than a proper sprocket ? hmmm can't wait to see more angles of this suspension layout !

looking at the GT, you're right, same ballpark...thanks for clarification. also curious as to why a "non yeti" platform.

I listened to a podcast the other day where John Hall mentioned some platforms work better on some travels than others. It was a good podcast, other than some guy from off camera that kept butting in, you should check it out.

Thought so as well, but after a second look it seems to be a round plate covering the pulley?

Agreed on the pivot being mid-high and split pivot design rather than Horst link. Rear end looks quite similar to the Hope HB916 but with a higher pivot and smaller rocker link as mentioned. I think this design lends itself to being quite flexible for fine tuning kinematics while still being nicely packaged.

Should we start placing bets on what the kinematic numbers will be???😂

There's got to be a linear rail behind that seat tube, right? tehe. It would make sense to use a six bar like their ebike, I can't see any definite evidence of it tho.

I'd imagine the chain rub on the sides would be unbearable if there was no cog, but it does look pretty smooth to me. Maybe it could allow them to fine tune the chainline? If it were me I'd use that link on the idler to fine tune the position, or maybe have it under some sort of tension.

Yeti always gets wild with their dh bike suspension, so i would expect something sorta novel on this one outside of  just being a high pivot/idler. we'll see soon enough

Quote at the bottom of the Richie video: “IT’S BEEN HUMBLING SEEING YETI WORK HARD TO BRING A DH RACE BIKE TO LIFE WITHOUT COMPROMISE. AFTER LEAVING THE SPORT ALMOST TEN YEARS AGO IT’S EXCITING TO GET THE OPPORTUNITY TO BE INVOLVED WITH ANOTHER YETI SPECIAL PROJECT.  RACING ENDURO OVER THE PAST DECADE HAS BEEN REALLY FULFILLING, BUT I AM EAGER TO EXPLORE DH AGAIN. I WANT TO PUSH MYSELF AT HIGHER SPEEDS AND GET IN TUNE WITH THAT DH MENTALITY AGAIN AND IDEALLY BRING THOSE BENEFITS OVER TO ENDURO. WHEN IT COMES DOWN TO IT, I JUST WANT TO GET ON A DH BIKE AGAIN AND HAVE SOME FUN.”

Looks like he will step into a few races on the new rig.

also judging by the shouting he's been on a spiked bottle again

Short links tend to be harder to optimize kinematics-wise than longer ones (thus Neko opting for the mother of all rockers) as the angle changes through the travel are more severe and can be more unfavourable in certain travel parts.

This can't be it, it's a Horst link!!

They hid the pivot very well and threw me off the trail with the chainstay being completely inline with the rear axle.

Yeah, I noticed that too.  And look at the seat tube, it's huge, with a cutout behind the rocker.  I bet it's 6-bar like their ebike, with the extra bar going from the swingarm through the seat tube to the rocker.

Whoa! There have to be some more links in that seat tube!! The chainstay probably isn't mounted directly to the frame, but via another short link and there's a dogbone link to the top link!

It says Sixfinity on the website but where is it hiding? Looks like the rocker could potentially actually be a split pivot and it also looks like something hiding in the seat tube behind the shock area…9F66B16B-0FAD-4F3A-AA08-EEBE3598FEF9.jpeg?VersionId=zQ

Exactly. You do not put a fender on the seatstay bridge to not cover the 'seat tube' with mud (you do it to prevent mud covering the links in there) and you do not make the seattube THAT chungus only to cut a hole in it without a reason.

Obviously I could be wrong, I did say it's a split-pivot about half an hour ago...

That void behind the upper part of the shock looks like a prime area for a 6th bar to connect the rocker and chainstay/lower link...
