Experience the pinnacle of cycling performance with this advanced disc rear wheel, meticulously engineered for the modern athlete. Thanks to innovative Total System Efficiency (TSE) carbon laminate technology, this wheel is designed to excel in time trials and triathlons, accommodating wider tires and lower pressures for optimal speed. The combination of a wider rim profile and an optimized tire interface effectively combats the four key barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. This wheel performs at its best with 28mm tubeless tires, allowing for lower inflation pressures that enhance grip and compliance while reducing rolling resistance. Integrated seamlessly is the TyreWiz 2.0 tire-pressure monitor, ensuring you can effortlessly keep track of your PSI/bar range without compromising aesthetics. The redesigned pump-access port makes inflation straightforward and hassle-free, eliminating the need for stickers. Featuring the premium ZR1 hub equipped with ceramic bearings, this wheel boasts 66 points of engagement for exceptional responsiveness.Aero, durable, and lightweight designTubeless compatibility for optimized performance with wider tiresEnhanced stopping power and modulation with disc brakes
