Exactly. The kind of stuff thrown around in this thread borders on the unbelievable or we have a couple of pro riders here that I wasn't previously aware of. I think I know a couple of really strong cyclists (notably, my brother but also others) and in spite of my injury I'm no slouch and am rarely overtaken on a regular racer but if I'm to believe this thread then I really should be checking my bike if something is dragging or not ;)
