I've always wondered what level of bicycle knowledge and repair knowledge professional riders have. For a professional rider I'm guessing they sometimes train with their team and sometimes they train alone. When training alone, they probably don't have a support car. So...do pros change their own flats when out training? (I'm guessing, yes.)

What sort of repairs do pros, like Cavendish, do when at home? Is he coming home and truing his wheels after hitting a hole? Or does he send out the wheel/request a new one? And yeah, does he clean his own bike?

I'm guess I'm just jealous that pros just get to ride and then head to the team bus for a massage. No cleaning or maintenance work. But, seeing Cavendish at home I'm guessing he does in fact do work. Plus, you could see a huge tool chest behind Leipheimer. And, I'm sure it depends on the rider. Some could be mechanics post-career, and some probably can't fix a flat.
