Firecrest shape with all carbon rims the 303 has been a longtime favorite for Zipp buyers. It's the perfect combination of aerodynamics, weight, comfort and reliability.

Zipp are also offering a hub color option for 2012 so either black or the original grey/silver
Weight of the 303 clincher is a claimed 1500grams
