Zipp 303 SW Disc Brake Centerlock Tubeless Wheel

The Zipp 303 SW wheelset brings together cutting-edge technology, aerodynamic design, and rugged versatility for the modern road and multi-surface rider. Engineered with Zipp’s proven Total System Efficiency (TSE) approach, the 303 SW is optimized for lower tire pressures, wider tires, and maximum speed across varying terrain—all while delivering real-time tire pressure monitoring via SRAM AXS wireless connectivity. Integrated AXS Wheel Sensor for Smarter Riding At the heart of the 303 SW is the Zipp AXS Wheel Sensor, seamlessly integrated inside the rim. This lets you monitor and analyze your tire pressure directly from your bike—no valve-mounted sensors needed. See a green light before your ride and know you're good to go. Adjust pressure during the ride to fine-tune performance, improve comfort, and catch issues early. Designed for Speed and Stability Inspired by the gravel-tuned 303 XPLR, the 40mm-deep rim features a wide 25mm internal width, ideal for 30–35mm tires. This modern profile delivers lower rolling resistance, high aerodynamic efficiency, and smoother ride quality—especially over rough pavement or long-distance routes. Performance Meets Durability A revised carbon layup boosts the wheel’s impact resistance by nearly 10%, maintaining a lightweight profile (just 1440g per set) while increasing toughness. The refined rim shape helps prevent pinch flats and enhances overall performance. At the core, the ZR1 hubset with stainless steel bearings offers long-lasting smoothness and reliability.
