Description
Most gravel wheels are modified versions of existing road wheels, focusing on stiffness and lightweight. Zipp takes a different approach. In gravel, resistance and vibrations from bumpy surfaces create a barrier that slows riders down. To combat this, Zipp applied Total System Efficiency specifically to the challenges of gravel. The wide profile increases air volume, allowing for lower tire pressures without squirm. That means you mitigate surface vibrations while maintaining grip when cornering or traction while climbing. The rim profile also creates a seamless transition with gravel tires for unsurpassed aero efficiency on gravel. And while the 303 XPLR SW is built big, it’s still lightweight to keep you fast and fresh for those long, fulfilling days in the saddle. The Zipp 303 XPLR SW is compatible only with approved tires.Size (wheels) 700cRim construction Carbon – HooklessTire compatibility Tubeless tires onlyRim depth 54mmBrake compatibility Disc (Center Lock)Rim - inside width 32mmRim profile SymmetricalRim finish UD Fiber, Impress valve graphic, Adhesive decalsNipple material AluminiumSpoke type CX-Ray - BlackSpoke count 24Spoke pattern 2 CrossDriver body type n/a, SRAM XDR, SRAM/Shimano RoadAxle type (Wheels) TA 12x142Bearings Cartridge - Carbon SteelDriver Mechanism 6 Pawls, Compression SpringMax tire pressure 50psi/3.45barMax recommended system weight 286lbs/130kgMax outside width 40mmWeight Based On Estimated lightest weight for wheelset configuration: 12mm through axles and XDR body.
