they look exactly the same, or am I missing something
you are missing something
Holy crap- Yeti SB66 porn!
- Thread starter shake_rattle_and_ roll
- Start date
you are missing something
It's nice and all but Yeti are only trying to achieve what the four bar did decades ago.
Actually looks more like this

I wouldn't say exactly the same, but my first thought upon looking at it was that the front triangle shape at least looked quite similar.
I just watched the videos of the rotating pivot several times (where they cycle it through its motion). Seriously, that pivot point look like it barely moves a centimetre at the most. It's astonishing to think that could have such a drastic affect on the performance over a fixed pivot in the exact same location (like most of their other frames).
Most other bikes have a linkage rear end weather it be Horst Link/Four Bar style (pivot at the end of chainstays) or DW (pivot at the beginning of chainstays). These pivots barely move throughout the suspension action but they do move enough to keep suspension isolated from pedal and brake forces.
Yeah... $2890 here

Remember pivots isolating forces belongs to the same line of belief as perpetual motion machines

[/QUOTE]So what you are saying is that bike companies have come up with multilink suspension for nothing, they are all wrong?
I don't know about perpetual motion but there is no denying that placing a pivot At the end of the chain stays isolates the suspension from braking forces and the modified wheel path can be designed to counteract the forces of the chain on suspension action under power. Placing a pivot at the end of the seatstays however does nothing.

Multilink suspension can have axle paths that would be impossible with a single pivot (most of them don`t, or are not far off a single pivot arc) and has nothing to do with breaking the 2nd law of thermodynamics. And if you say a chain stay pivot isolates forces would`nt it then isolate the force you apply to the crank and fail to drive the rear wheel or is it like a diode and only works in one direction

Ah, your one of those types. You learn a few big words in your 1st year physics class and like to regurgitate them without really knowing how or when they should be applied.
Perpetual motion has nothing to do with bicycle suspension. FAIL. I look forward to the day that my bike can power itself without an engine or a self powering one but honestly I don't see it happening.
ANYWAY............The fact that most may not be 'far off' a single pivot arc means that their path is indeed modified. On a bike very slight differences can have massive effects on the characteristics of the ride. As an example, you wouldn't think that 1 degree difference in a head angle would change much but it does.
The proof is in the pudding as they say, if you think a single pivot rides like a Horst Link then you should get out and ride a little more. Too much time in the lab makes for a dull and experience lacking nerd.
Oh, and don't take things too literally. Im not saying the rear end of a four bar is completely isolated from all forces but it does a much better job of it that a single pivot.
Really sorry to the rest of you for turning this thread about a pretty cool bike into a dull physics debate.
There goes the bell Brute, class resumes never.

Yep. For pure entertainment, only beaten by the online vs. LBS weekly dust-ups.
On a serious note. This could be a future replacement for my beloved Tracer.
