Zipp’s ultimate aero weapon is now tubeless ready. That means you get the many aero advantages of the 858 NSW Tubeless rim-brake wheelset with the added benefit of increased cornering grip and compliance with reduced rolling resistance. The wheelset’s 19mm internal width is optimized for running wider tires at reduced air pressure. The 858 NSW’s undulating 77/82mm-deep rim shape, our proprietary Sawtooth™ profile, takes design cues from nature for our highest performing wheel when it comes to aero efficiency and crosswind stability. These structures inspired Zipp advanced development engineers to, for the first time, systematically apply biomimicry to solve the complex challenge of designing a wheel, with the undulating Hyperfoil™ nodes, that reduces both aerodynamic drag and side force. Simply put, the 858 NSW Tubeless is ideal for those focused on triathlon, time trials, or aggressive road riding.
Zipp wheels, handlebars, stems, and seatposts come with a lifetime warranty for product issues while riding. The lifetime warranty is not transferrable. Proof of purchase is required
