The Zipp 303 NSW Tubeless Carbon Clincher Wheelset has been redesigned for 2018, providing the best-in-category aero efficiency and stability thanks to Zipp's dedication to AeroBalance�. Featuring a new, wider 19mm inner diameter, the new 303 NSW is optimally paired to the day's modern wider tubeless tires.

Retaining its 45mm depth, the 303 NSW still features Zipp's ShowStopper� textured brake tracking surface for unrivaled performance in all conditions, while their revised ABLC� Sawtooth rim dimpling pushes the performance with reduced high yaw drag and improved crosswind stability. A full-carbon construction helps keep things lightweight and stiff, and each rim is handcrafted in their Indiannapolis, Indiana factory.

Built on pro-proven 77/177 hubs with optimized hub flange geometry and spoke hole attachment pattern with Sapim® CX-Sprint spokes to optimize torsional and lateral stiffness while improving durability.
