Regarding The Chain Suck incident, a SRAM rep interviewed theorized Andy was in his 38 ring and, to put the hammer down as he attacked while avoiding the slower shift up front, he dropped it into his smallest cog....the extreme angle, perhaps a bit of chain rub, simultaneously hitting a bump, and all that released torque caused the chain to miss. Anyway, the implication was that SRAM stuff doesn't fail-- must have been Andy's extreme shift and other variables.

My neighbor speculates that Alberto spit some gloppy stuff on Andy's jockey wheels just before.
