you all are the tech gurus, so enlighten me. this proto looks pretty high pivot. aren't most riders/brands settling in on mid-pivot after a few years of high-pivot stuff? or am i mistaken?

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?
for me there are two answers:
1-some suspension systems are that bad efficient that high pivot make it better(Antisquat)
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.
Am I wrong thinking a Horst link bike has the chainstay pivot below the rear axle (assuming a line drawn between the centre of both front and rear axles)?
is the centre line of the chainstay pivot slightly above the rear axle?
I still have one of those boxes, can't even remember what was in it.
I'm guessing the Totem goodie box was packed full of spare seals and bushings. I never had a Totem, but all my friends that did said the forks always needed a rebuild and ate seals and bushings like cookie monster eats cookies.

That's a minor detail, I think Rocky got around the FSR patent by putting the pivot above the rear-centre line, so technically yes, but I'd say if the pivot is on the chainstay near the rear axle (and the brake link is floating obviously), then we categorise it as a horst link. It's gonna function more or less the same regardless of where the pivot actually is. QED, remember the older Demo where the main pivot was concentric so they could drop all the pivots, including the chainstay one? You can do something similar by raising all of them if you wanted for example.
And it very much looks like it's a 6-bar anyway, so the whole horst-link discussion is moot

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.
that pulley location reduces the negative effect of the derailleur clutch by keeping the chain in more of a parallelogram shape so there isn't as much growth
Remember speaking to a zerode athlete in October last year, he mentioned that zerode would be bringing back a dh bike but didn’t say anything about frame material or drivetrain system
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...
the 6th bar goes outside the seat tube on the 160e, most likely to accommodate the dropper. DH bike doesn't need a dropper, so that wasn't a design constraint.
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...

On high pivot design, you can get similar effect than switch infinity (or their 6 bar) by moving the pulley wheel instead of the main pivot.
This is possible since pulley don’t need to accept different diameters with fixed tooth count.

Probably because different suspension designs work best in different travel ranges.
Will new XO have alu/alloy cranks and cage? Not sure if those pictures have been here before.

Looks about right. 9 cogs machined out of steel, 2 steel (die cut?) ones pinned and then last alloy 52T pressed on. Too bad they went Shimano route with all the pinned sprockets because the current eagle cassettes with 11 machined cluster are the cleanest looking. The new cranks look really nice. 5dev vibes.
@sprungmass I think the 52T is a spider/carrier, the two smaller aluminium rings are pressed/pinned onto it and the lower 9 gears still appear to be single piece, as currently. Should make for a cheaper to make (cheaper to buy?) and a lighter cassette. With less endurance though (but Shimano also has 3 Al rings on the XTR cassette, 2 on the XT, 1 on the SLX and 0 on Deore).
Integrated bashguards*

xtr cassette is made of cheese unfortunately. buddy of mine trashed his after 3 months and most shimano pro‘s are running the xt one because of unreliability.

2- is in fashion to go high

Re Totem, meh, I got swindled!
Kinda funny that Richie Rude won South Africa on the same Saint groupset that's on this prototype 10 years later.
Old does not mean obsolete 😆

You can see the edge of the dogbone link inside the seat tube too, unless that's an oddly asymmetrical seat tube.
Another company back in the dh game
zerode!
Their Instagram post has #pinion #gates
So gearbox belt drive dh bike?
Good to see them back in the game!

if you go to wheelbased.com they have a article on yeti suspension designs.
they show something like the dh bike .
This one? https://wheelbased.com/2021/09/02/6-bar-suspension-linkage-with-drive-t…
yes.
the 6th bar goes outside the seat tube on the 160e, most likely to accommodate the dropper. DH bike doesn't need a dropper, so that wasn't a design constraint.
...does look nice though!!

On the topic of Zerode - 19.03. is the date!
Looks like horizontal shock, hp-Horst link without the excessively high pivot, the frame doesn’t look like a tank!
I would say still an "excessively" high pivot. There is a weird square jonction in front of the BB.
Probably because different suspension designs work best in different travel ranges.

That bash guard on the chainring looks like it has the eagle logo on it?

Too bad they went Shimano route with all the pinned sprockets because the current eagle cassettes with 11 machined cluster are the cleanest looking. The new cranks look really nice. 5dev vibes.
Looks like integrated chain guides on the chain ring itself.
Leaked press release says bashguard compatible, but no need for a chain guide.
