Zipp’s 858 NSW wheels are now faster than ever, thanks to their Total System Efficiency (TSE) technology. This design includes a tubeless, hookless rim that reduces weight and creates a smooth fit with the tire. Despite having deep rims, the 858 weighs as little as much shallower wheels. Its 23mm internal width is ideal for wider tires run at lower pressures, which helps reduce rolling resistance. TSE technology addresses four key speed barriers: wind resistance, gravity, rolling resistance, and vibration. The rim’s unique 85mm depth and patented Sawtooth shape improve aerodynamic performance and stability in crosswinds, making it perfect for triathletes, time trialists, and speed-focused riders. While it’s optimized for tubeless tires, it also works with tubeless-ready tires and tubes. It.
