Zipp 303 Firecrest Rear Wheel Disc Brake (Clincher)

Zipp's Firecrest 303s give you the speed to take the hole shot and the control to maintain it. Built on ultra rigid 45mm-deep carbon rims, they slice through the mud, sand, and wind with predatory force, always hungry for the win. At 28.5mm-wide, the rims offer an extra-wide platform so you can run lower tire pressures for diminished rolling resistance and better grip in the corners, all without the fear of flatting. Disc-compatibility reigns in an era of smooth, dialed braking control, which translates to more speed and less wasted energy. Zipp’s stiff hubs and Sapim CX-Ray spokes provide the finishing touches.
