Zipp 202 NSW Carbon Tubeless Rear Wheel Conquer steep ascents and surge ahead on high-tempo flats with a lightweight rear wheel built for pure responsiveness. The Zipp 202 NSW Carbon Tubeless Rear Wheel is engineered for riders chasing every possible performance edge when the road tilts upward. Its versatile 35mm rim depth achieves an exceptional balance between minimal rotating weight and streamlined aerodynamic efficiency, giving you the explosive acceleration needed to attack on climbs while preserving effort on fast descents and open valleys. Peak Efficiency and Instant Power Transfer At the heart of this climber's dream is the flagship ZR1 SL hub, featuring custom hybrid ceramic bearings that roll with frictionless ease. Equipped with a 6-pawl compression driver mechanism delivering an incredible 66 points of engagement, every watt of pedal force translates into immediate forward propulsion without energy loss. The modern 23mm internal width and hookless rim design optimize wide tubeless tires from 28c to 32c at lower pressures, drastically cutting rolling resistance, dampening road harshness, and keeping fatigue at bay during long days in the saddle. Precision Build and Uncompromising Protection Crafted with high-tension Alpina Hyperlite spokes, Sapim Secure-Loc anti-rotation nipples, and a sturdy 12x148 thru-axle setup, this wheel provides remarkable torsional stiffness for sharp cornering and high-torque efforts. Compatible with Center Lock disc rotors and capable of supporting total system weights up to 115kg, it is a ultimate high-performance upgrade for modern disc-brake road frames. Best of all, Zipp backs this elite wheelset with their comprehensive Lifetime Warranty, guaranteeing long-term durability and absolute peace of mind on every summit push.
