Zipp 303 SW 700c Road Wheel – Front
The Zipp 303 SW Front Wheel is the high-performance all-rounder that’s rewriting the rulebook on road, gravel, and cyclocross versatility. Inspired by the gravel-proven 303 XPLR, this modern classic delivers exceptional speed, comfort, and durability—no matter the surface. From buttery tarmac to bone-rattling cobbles, the 303 SW stays smooth, fast, and unflinching.

Engineered for Real-World Speed
With a 25mm internal rim width and optimized aerodynamics, the 303 SW supports wider tires at lower pressures, reducing rolling resistance, increasing comfort, and minimizing rider fatigue. A revised carbon layup delivers 10% more impact resistance, while the hookless rim shape enhances strength and flat prevention. The built-in AXS air pressure sensor lets you dial in tire pressure in real time—no guesswork, no pump fumbling.

Built to Go the Distance
At its core is the precision-machined ZR1 hub with stainless steel cartridge bearings for long-lasting smoothness. Whether you’re racing a cyclocross course or crushing a weekend gravel epic, the 303 SW keeps you planted, efficient, and ready to roll.
