I am a rider that loves racing in TTs as well as criteriums and road races. I have recently begun searching for wheels that are aerodynamic. Weight is of secondary importance in this case. I have checked out specs of, Bontrager Xlites, Bontrager Aeros, Campagnolo Eurus, Mavic Ksyrium, Ritchey DS, and American Classic 420's. The 420's win easily on paper from a performance and a servicability perspective, however i am concerned that this is an aluminium rim with very low weight. Is there anyone out there (in Australia or anywhere else) who has experienced these wheels first hand? Any problems?
