No idea, I think they are trickling out. My LBS had a few '12s I walked out with a medium 575. Granted it's a little down the road from yeti hq.... No carbon flex points.
I love mine so far!
I would send an email they are pretty quick on replying.
They are available now. I have one at the lbs waiting for a new headset.
They even have lime if you are into that funky color.
Wonder why Yeti hasn't updated their website. Seems like they'd want the details out on new changes for 2012...or maybe they don't. The change to the aluminum seat stay is still a bit of a mystery to me. Seems the carbon flex point provided a enough flex to build into the suspension curve. Other threads have mentioned that the flex of the aluminum stay (2mm) is now similarly accounted for in the suspension tune, but if that was optimal why didn't they just do that in first place. I'm just wondering if the change provides any different ride impressions (either good, bad or indifferent).
I also find it odd that Yeti hasn't updated their site to the 2012 line. I'm having a hard time nailing down the specific specs for the 575 Enduro and Enduro Plus. Even reached out to Yeti a week ago and haven't heard back. Anyone know where we can find a spec list for the 575s?
