For the same reason that there are racing and training wheels, there is also the Training bibshort that represents a big value with most of the features of the race short.

Sure you can notice the difference, but it's still an outstanding short with the same anatomic cut of the race short, a Kiss seatpad, Affinity Lycra, and the comfort plus leg band. This is the only piece in Castelli Servizio Corse program that is not used by the professional teams.
