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 and fast 66-point engagement.

Great way to charge both the bike and range extender/extra battery at the same time reducing charging time and charging each one by one. Very convenient and useful.

Literally EPIC
Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.
