Huge fan of the SB66. I've been beating on mine for trail and DH, and it's holding up just fine.I probably would break that too.
Still haven't made any decision on what I am going to do yet. Still waiting to hear from the guy I bought it from to see if he can get it exchanged for me. Looks like repair and paint would run me $500 from a reputable carbon repair company (local).
Regardless of what direction I go, I think I am going to get an aluminum frame.
