I have no idea if Cancellara motor-doped or not, but what made me very suspicious of him, without thinking of motors, of course, was his performance at the 2009 Worlds TT in Mendrisio. I remember the moment he overtook Wiggins and just left him standing, and that didn't seem kosher to me. Granted, Wiggins wasn't going particularly well in that, but still.
Generally, I tend to be suspicious if people do too many things too well. That may be silly, but I've got the impression that it's what doping of whatever kind does.
