Re:
Mike, exactly the same happened to me a few months ago with a TNT rear! It'd just been sitting in the bedroom, and a big chunk's broken off like yours. The wheels did seem a bit over-tensioned and I'd assumed that was the cause, but maybe TNT are particularly crap. The front (Hershey Ti) is ok.
I was thinking of getting another flange machined and bonded on... :|
