The 353 NSW is Zipp's top-of-the-line wheelset for endurance riders and road racers. It's lightweight aerodynamic and built for climbing featuring advanced rim technology and ceramic bearings for durability and smooth performance. It's also Zipp's first wheelset with SRAM AXS connectivity thanks to the built-in AXS Wheel Sensor. This allows you to monitor tire pressure in real time-no valve stem gadgets needed. A quick check before and during your ride helps optimize speed comfort and safety. A new carbon layup boosts rim impact strength by over 16% making Zipp's lightest wheelset even stronger. Its 40mm rim depth offers speed stability in crosswinds and low rolling resistance. The 353 NSW uses the lightweight ZR1 SL hubset with ceramic bearings to maximise efficiency.Versatile endurance wheelset for the modern road bikeFirst integrated connected SRAM AXS wheel with Zipp AXS Wheel Sensor; ability to use sensor with compatible tubeUD Carbon hookless rim construction 40mm depthZR1 SL disc brake hub with ceramic bearings CX-Ray spokesTSE for greater efficiency and reduced rolling resistanceSawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depthOptimized for 30mm tires compatible with tubeless tires onlyCenter locking rotor interface.
