The Zipp ShowStopperT Brake track allows extreme versatility through dry, wet and dusty conditions. The New 303 Firecrest is a machine of versatility and strength. A race wheel for all year round. Experience Advanced Development Defined.

The year of the Tubeless

The benefits of Tubeless include superior flat protection, the ability to run lower pressures, and a smoother ride with high cornering grip and low rolling resistance. This wheelset, though, allows you to run Tubeless or traditional clinchers.

66 points of Hub engagement goodness

With the new ZR1 DB HubT offering 66 point of engagement, Experience power transfer, that's never been seen before. All ZR1 DB HubT sets come with Quick release swappable end caps to work with Quick Releases and Through axles. Opening the wheels to be used whenever and wherever straight out of the box.

ABLCT SawToothT

Zipp's new Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 32km/hr. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim's profile to further reduce high yaw drag and improve crosswind stability. Tha payoff is a faster more capable wheel able to handle anything thrown at it. deflection for reduced rolling resistance.
