All around aero performance

The Zipp 303 Firecrest is the perfect all-rounder. The rim has enough depth that you feel the aero advantage when pushing hard on flat roads, while being light and shallow enough to really perform in punchy climbs. You can choose the 303 and be confident that you won’t need another wheelset, they do it all.
The 303 Firecrest Carbon Clincher wheelset is now even better and lighter. At the center of the wheelset is Zipp’s 77/177 hubset, an innovation that results in improved stiffness, durability, simplicity and usability. The 77/177 hubset is the perfect compliment for the leading aerodynamics, ride quality, stability and rim strength of Zipp’s Firecrest rim technology. That means you get the unmatched performance of the 45mm-deep 303 Firecrest rim and Zipp’s groundbreaking Carbon Clincher technology, with its exceptional reliability, handling and aerodynamic performance with the added convenience of a clincher.
You’re at the helm of a serious Speed Weapon that helps speed up and smooth out even the most chaotic courses. That’s true even when the conditions and terrain get crazy.
