Zipp 303 SW AXS Smart Sensing Tubeless Road Wheelset

The Zipp 303 SW Tubeless Disc-Brake Wheelset redefines versatility for modern riders, blending road efficiency with gravel-capable durability. Featuring SRAM AXS-connected tire pressure monitoring, this wheelset delivers real-time performance optimisation across tarmac, cobbles, and light gravel. The 40mm deep, 25 mm-wide hookless rims enhance aerodynamics with wider tires (30–44mm), while a 10% stronger carbon layup boosts impact resistance. With ZR1 hubs (stainless steel bearings) and Total System Efficiency (TSE), the 303 SW smooths rough terrain, reduces rolling resistance, and keeps you connected to your tire pressure—no external sensors needed.
