The Zipp 303 NSW is evolved from the winning formula of the innovative Firecrest. Like its siblings, 404 NSW and 808 NSW, Zipp's engineers in The Nest advanced development lab made improvements in aerodynamics, durability, braking performance, and reduced rolling friction to produce the lightest, highest performance 303 wheelset Zipp has ever made.

The aerodynamics are new and improved and feature Zipp's ABLC Sawtooth™ technology. This new Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.

The new Showstopper™ brake track is a complimenting pairing of a directional, molded-in, texture with silicon carbide particles suspended in the surface resin which delivers predictable modulation and quick stopping in wet and dry conditions.

Featuring a new and advanced carbon layup, the NSW rims are engineered to withstand the rigors of a heavy race and training schedule. Zipp's Impress™ graphic technology prints graphics directly on the wheel, to help allow the dimples to do what they were design to do – help control vortex shedding, the rate at which air sheds off the wheel. Managing this is crucial to stability. ImPress graphics also give NSW a distinctive stealthy look.

At the center of the 303 NSW wheelset is Zipp's Cognition hubset. Built to provide the lowest rolling friction possible without compromising sealing, the hub's Swiss-made bearings work in tandem with Zipp's new Axial Clutch™ technology to dramatically cut rolling friction when compared with conventional freehub systems.
