Giant engineers laughing all the way to the bank. Have any of them put a pen to paper since 2014?

Just slacken the head angle and adjust reach and stack and lower standover, its all anyone else is doing really. The suspension platform is solid, it doesn't need to change, just like all the horst link bikes out there. 

The suspension platform might be the same, but probably anti-squat, anti-rise, axle path have been modified. Pretty sure they need to, cause the geo change would put the rider in a different position, also slackening the HA would make the bike more aggressive - another reason to modify it. When you put everything together, it might be a whole new, different bike compared to the previous one, performance-wise. And the looks? Might be close, but the new proportions and small changes in tubing here and there make it look faaar better! Smile

It's a shock version of the totem. Called the scrotem. I'm guessing it'll be extra supple and sensitive.

Any thoughts - guesses? - on which of the new AXS components could be interchangeable with existing AXS?

I’m assuming the new derailleur, cassette and chain will all be needed and for now the new crank. But at some point I’d think Wolf Tooth and others will make a chainring that works with current DUB cranks. 

And could, say, you just buy the new controller to work with existing AXS? Would it pair?

It appears that the only thing interchangeable would be the XX1 Quarq Dub SL cranks since they use 8 bolt mount. If SRAM doesn't release a 104 BCD T-Type chainring for the Quarq spider then like you said Wolf Tooth or Garbaruk will. 

As for the controllers, the whole point of AXS is to have cross compatibility between the different products in that lineup. Drop bar shifters, old Eagle AXS shifter and the new one should all coexist.

Hopefully new axs derailleur is going to work on Shimano Cassette/chain. Frankenstein drivetrain has been bullet proof for me. Also hope they fix the weak clutch. Only gripe I have is the clutch

On the face of it, the only thing that could prevent that is the pullies might be flat top chain specific. If that's the case then old (current gen) pullies probably fit in. Or an aftermarket company might make pullies for this if that's not possible.

now THAT would be news!

But: Richie is scheduled to tackle the EWS podiums, isn't he? Who would pilot their bikes?

(I know, that's rather a question for the team rumours thread, but I feel to make sense of a DH bike they'd have to race it?)

Carbon is bold. Seems like a lot of brands are moving to Al or lugged for DH race bikes. Super exciting tho!

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.

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?

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

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 !

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???😂
