303 S Tubeless Disc A1

Description

The Zipp 303 S Tubeless Disc A1 is designed to excel on every terrain—from smooth pavement to rough roads and light gravel. With a 45mm rim depth and a significantly wider internal width, this wheel delivers improved aerodynamics, stability, comfort, and overall ride quality in nearly every measurable way.

Optimized for top aero performance with a 28mm tire, the 303 S is also versatile enough to run gravel tires up to 50mm wide. The 27mm outer width and 23mm internal width support modern, wider tire profiles for lower rolling resistance and a smoother ride.

Equipped with Zipp’s reliable 76/176 DB hubset with a Center Lock rotor interface, the 303 S is a fast, efficient, and capable front wheel for riders who want true all-road performance in a lightweight carbon package.
