WTF happened to the crank? And did he take a piece out of the disc.... Maybe it was 150 miles straight downhill. The S-Works is a nice bike, it was one of the few FS I tried out that I thought fit right.
Oh, and I'll add that Race Face cranks are awesome. Maybe it's the bottom bracket they use, but compared to similar Shimano cranks, they feel 2x stiffer.
