I don't remember all the Yeti 6 bar patents but I think most of them (if not all) used a 4bar to emulate a linear path in order to replace the switch infinity slider. Like the one in your image. This one uses a scissor link which is effectively close to a Chebyshev link which is basically a single sided Watt link. And some patents used a Watt link too.

See. This is how it happens. All these names and links are how Crab sows contempt and discord amongst the masses. An NSA psyop has nothing on Crab

What throws me off is the double shear interface between the SS-Rocker, usually the bearings get put in the Rocker and the SS has the overlap, but this frame has it the other way around. No brand I know does it this way, I think if we find who does this with their rockers, we find the brand behind the proto.

I should have emphasised the vertical shock layout to be fair. Does this pre-date the UBB layout they were doing or nah?

why do they need to release something new? geometry is still spot on, the only thing i would change is shock orientation to increase dropper insertion. oh and a motor version of course

I don’t know if you guys have ever owned a banshee but they’re pretty poor quality frames unfortunately. I had some of my closest friends ride them and they kept breaking chain stays, hardware kept coming loose and snapping pivots. Warranty was good, but it happened so many times that they had gotten rid of them for something else.   seems to be from today, but they did feel a little bit too high  a little bit to steep head to angle wise.  But who knows with aluminum bikes as they are usually pretty far off of what their numbers suggest

Specialized does this sometimes. They did it on the Enduro, but put the bearings in the rocker for the Stumpjumper Evo and now have the bearings in the SS again for the Stumpjumper 15. Current Norco Sight does have the bearings in the SS, too.

The cable entry design at the headtube, lack of in frame storage, and the overcomplicated pivot/link situation at the bottom bracket, all lead me to suspect Yeti. 

I feel like Yeti needs something complicated like dw6 or switchfinity is to convince people they are buying the premium suspension option. Meanwhile, suspension designs from 30 years keep winning every DH world cup

Look at the chainstay – it looks nothing like any Yeti ever made: squared-off, sharp edges. And the cable port? On Yetis from the past few years, those are screwed in.

Do you guys throwing out these opinions actually look at bikes?

I bow humbly in front of your greatness. Clearly you are the all knowing expert. 

Will you kindly grace this ignorant peasant with your wisdom on what bike company created the prototype?

If I may interrupt the bickering... This page says 998, but the Hub says 999. Either way, we're close to a thousand pages in this thread! Who's buying the keg and where will it be?

We can only hope that a new crab link bike is dropped today so it takes its rightful place as the centrepiece of page 1000

I am here for semi meaningless contribution on the road to 1000. Back to the Demo... let's dig deeper into the chain routing and what we feel is being hidden and will be revealed soon. What is behind the housing that we cannot see? I know the links are more hidden for protection but there's more going on in there..........

Maybe something to do with the idler that appears to sit on the bottom bracket axle?

Definitely! Thanks for the solid linked pic as well!

Yeah, thats what I am trying to wrap my head around because there's definitely more beneath the surface on that one... Be freaking cool if its a way inside that they can totally isolate the drivetrain from suspension

It still has a rear derailleur, so it's not a gearbox.. I'm thinking a 2 chain deal like the Pivot, just a different location on the main pivot ..

Normally the easiest way to identify the brand is where it's been ridden. If it's Bellingham it's Evil or Transition, Colorado it's a Yeti etc etc. 

But it's safe to say that the proto isn't coming to market. Full carbon frame in 2023 and we haven't seen it again since? They tested it and for whatever reason didn't continue with that design.

A crab bike, without size specific chain stays, and a 64º head angle.

That proto frame goes way back. I shot this photo of it in the early fall of 2023. Sorry for poor quality. The obvious heel rub and linkage swap-out (on your more current photo) shows it's seen a lot of hours. The guy riding it started working for a different bike company, so he may have offloaded this one to another industry friend. At the time, I was thinking it was maybe a Diamondback prototype that got canceled/never saw the light of day. He was fairly open with it; it was spotted at local Seattle area watering hole(s), etc. rig1.jpg?VersionId=v3fsw8zeKRFTokHm1HpBC

Could it be a salsa proto ?

-cable ports and frame layup look similar to carbon cassidy/blackthorn 

- salsa has previously used split pivot so a jump to another DW system wouldn’t be a huge leap 

Totally agree that this looks most closely like a DW6 linkage arrangement.  The referenced Yeti patent lacks a link on the chain stay and Sixfinity is a has a different linkage configuration

It was said somewhere, I wish I could remember where, that it has an internal jack drive from the BB to the upper pulley.
