Tick the miles away with Zipp’s 30 clinchers. Built on stiff, strong and nimble 30mm-deep aluminum rims, the 30s are rugged, light and fast. In accordance with Zipp’s cheat-the-wind philosophy, the 30s employ their advanced wide and super-aero, round-edge toroidal rims to minimize wind drag so you can add speed and also save energy. Plus, the 21.5mm-wide rims accept wider tires, too, for superior cornering and comfort while simultaneously helping to prevent pinch flats. These fine wheels also boast Zipp’s durable, smooth-rolling hubs and Sapim's stellar CX-Ray spokes for years of road-riding fun and excitement.
