Everyone acts all surprised. Pros have been painting their bikes to fit their sponsors for years. This is not new or unheard of. It's a regular practice in all professional sports. look at the kickers shoes in the NFL, you'll see a pony(or whatever) logo in sharpie over the tape when they're actually wearing a high end soccer shoe. This is old news. There was a thread not long ago about a female tt champ who's "fuji" bike was on ebay and it was clearly a cervelo.
Are we that naive?
