This is a great tubular. I ran a set of these on my Zipp 303 for the entire summer, not just racing but training as well. Probably put 1400 miles on this wheelset last summer and these babies are still looking good. No cuts or major nicks and the no typical back tire wearout. Yet, during any rainy rides they were not scary to be on, good rubber. I am running 25's. These will not disappoint, and the price is right.
