I agree, the pros ride whatever bikes sponsor or cosponsor their teams. Only the top riders in the world have the luxury of having bikes custom made for them by a company other than the one on the decals. Lemonde and Merckx reputedly did this, but even the top riders usually don't bother. And Merckx was a special case whose bikes bore his own name for most of his career, and who actually went into bicycle manufacturing after his retirement from competition (LeMonde seems to have been mostly a figurehead for the bikes bearing his name). When you think what it takes to succeed at a physically grueling sport like cycling, it's not surprising that most pro riders will have a "jock" mentality, which only rarely mixes with an interest in engineering.
