The Mavic Ksyrium Elite Ust Front Wheel has been a benchmark for reliability, light weight and versatility for more than a decade. This updated version makes it easier than ever to experience the benefits of riding tubeless. Integrated with the Yksion Pro UST Tubeless tires, the system makes installation, removal and maintenance simple and hassle-free. Eliminating the tube reduces friction in the system, which means less rolling resistance and higher speeds. You can also lower your tire pressure, which gives you a smoother, more comfortable ride plus added control on rough roads. And youll enjoy a reduced risk of punctures, so you can ride with confidence and push yourself farther.
