On the cutting edge.
Redesigned for 2018, the new 303 NSW Tubeless Carbon Clincher from Zipp provides the best-in-category aero efficiency and stability thanks to Zipp's dedication to AeroBalanceÃ¯Â¿Â½. 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 ShowStopperÃ¯Â¿Â½ textured brake tracking surface for unrivaled performance in all conditions, while their revised ABLCÃ¯Â¿Â½ 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.
