Zipp 303 XPLR S Carbon Disc Tubeless Rear Wheel

This wheelset is the fastest on gravel, thanks to its mega-wide rim that integrates seamlessly with approved gravel racing tires.* 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 S is built big, it’s light to keep you fast and fresh for those long, fulfilling days in the saddle. The Zipp 303 XPLR S is compatible only with approved tires.Orientation (wheels) RearSize (wheels )700cRim construction Carbon – HooklessTire compatibility Tubeless tires onlyRim depth 54mmSurface texture SmoothBrake compatibility Disc (Center Lock)Rim inside width 32mmRim profile SymmetricalRim finish UD fiber, adhesive decalsColour (Decal) StandardNipple material BrassNipple anti-rotation Sapim Secure-LocSpoke type CX-SprintSpoke count 24Spoke pattern 2 CrossHub 176DDriver body type SRAM/Shimano RoadColour (hub) BlackAxle type (Wheels) TA 12x142Axle material Aluminum front & rearBearings Cartridge - Stainless SteelDriver Mechanism 3 Pawls Leaf SpringDriver body material AluminiumMax tire pressure 50psi/3.45barMax recommended system weight 286lbs/130kgMax outside width 40mm
