The Zipp 303's, with its Firecrest rim technology, offers superb aero performance, straight-line sprinting stiffness, great stability in crosswinds and are ideal for climbing. Also being lightweight, they deliver precise handling on tricky descents and crisp accelerations when the pressure is on.
Firecrest moves the center of pressure of the wheel backwards, giving the 45mm-deep rim the crosswind stability of a box-section rim. At the same time, the 26.4mm-wide brake track (at center) allows the clincher tyre to take on a wider, more stable shape without compromising rolling resistance.
They are engineered for the classics yet are ready for anything you throw at them.
