Zipp is famous for their pro-level aero wheels that offer awesome aero numbers, but what if lightness and control are the goals? Enter, the 303 NSW Disc wheelset.

The 303 NSW Disc wheelset represents Zipp's commitment to the "challenge" rider and gravel grinder. Zipp manufactures the 303 NSW rim in-house at their factory in Indianapolis, so you know you're getting a refined product with incredible quality control. The 45mm deep rim features a bullet-nosed profile that adds stability in gusty conditions, while the rim's Aerodynamic Boundry Layer Control (or ABLC) dimples reduce turbulence in constant crosswinds at a wider range of angles. In fact, the lowest drag numbers were found using 28mm tires.  The 21mm interior rim width allows the tire to put a wider "footprint" on the pavement (or gravel) that adds control in high-speed corners while lowering rolling resistance. Yes, you read that right.  24 stainless steel Sapim CX-Ray spokes front and rear ensure long-term durability over rough surfaces. The wheels are also tubeless-ready, and come with tubeless valves and tubeless rim tape.

Zipp's Cognition hubs are made in Portugal and handbuilt to the rims in Indianapolis. The rear Cognition hub uses an alloy freehub body with an Axial Clutch ratchet mechanism, reducing friction while coasting. By using magnets -yes, magnets- to re-engage the cassette body, the Zipp Cognition rear hub eliminates friction and the need for components that wear slowly over time. Swiss bearings are used in Cogntion hubs, ensuring extremely low friction over every mile. Brake rotors are installed using centerlock format (lock rings not included).

A set of Zipp Tangente quick-release skewers, wheel bags, valve core removal tool, 10/11-speed freehub body spacer, Zipp Cognition freehub oil,  Zipp Cognition thru-axle hub caps for 12mm and 15mm thru-axles as well as quick-release skewers.
