Zipp’s 101 clinchers are fast enough to race and strong enough for heavy-duty training. Their light weight lets you climb and accelerate with ease, while the nimble-handling 30mm-deep aluminum rims also feature Zipp's stiff, impressively aerodynamic toroidal profile for free speed and energy savings you'll love. The 23mm-wide 101s are stiffer laterally for superior handling and they have a comfortable ride and even help prevent pinch flats due to the wide tire bed, too. They also boast Zipp’s fine hubs that employ oversize axles and smooth Swiss steel bearings. Plus, you get Sapim's stellar CX-Ray spokes. Upgrade to Zipp 101s and take your road riding to the next level!
