Its a 2006 frame... I didn't buy it new; I bought it from the classifieds from GoogNoog (now called goog, I believe).
The JRA claim was a bit tongue in cheek... I've ridden this bike properly for quite a while - this is its 3rd summer in the alps, plus plenty of fun in Wales.
But! I still don't think it should fail at the weld like that; I think the weld went (possibly assisted by the turning moment from the brakes), and the carbon hinge went as a result.

I'd love for Yeti to give me a brand new ASR-7... but I would be over the moon if they gave me a new frame, or even just a new swingarm.
Most likely, I expect they will sell me a new swingarm at cost; and that would be fair of them. I've sent them a friendly email saying that I love the bike, and can't really afford to replace it at the moment.
We shall see :o)
