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?

Cheers
