peloton said:Is it common riders get to keep all the bikes when switching teams, or do they have to buy them for smaller cost etc?
Depends on the rider. Some riders are lucky to get the latest frames and latest equipment. Most riders also have to give back bikes at end of year for end of year sales. Garmin are currently selling Cervelos on their website.
I remember Wegelius after he retired had no bike as he had to give them back to lotto.
