I don't trust the carbon knuckle thing on the seatstay.
Why? Carbon is perfectly OK as a flex point. Nip into a fishing tackle shop and see what rods are made out of and see how much carbon can be made to bend if necessary, and properly constructed.
I had a 575 for 18 months or so. Lovely bike, superb mega-distance machine (I did the TransWales on it) easy to build up light if that floats your boat. Climbs superbly too. As a do-it all XC/Trail/AM bike I doubt it has a serious rival.
BUT
It's versitilty can be it's undoing: Jack of all trades, master of none. I found the carbon stays too flexy in the end, and yes, you do feel a bit perched on top (Which can be a good or bad thing), and they do blow through the travel easily (Use the Propedal properly and it's not an issue 95% of the time though)
For what I wanted at the time, it was perfect. They are beautifully made and finished, and good VFM in the grand scheme of things. But in the end I couldn't ride it hard enough because of the flexyness.
I flogged it and bought a Pitch, which is a bit more downhill focused, stiffer and burlier. 2/3 of the time the Yeti is 50% better than the Pitch, but for the other 1/3 of the time, the Pitch is 500% better, IMO….
