Zipp 353 NSW Tubeless Disc Front Wheel

The Zipp 353 NSW Tubeless Disc Front Wheel is Zipp's most technically advanced road wheel — a front wheel designed around climbing performance, aerodynamic efficiency, and a level of technology integration that goes beyond what most wheel manufacturers offer. At $2,000 for the front wheel alone, the 353 NSW is positioned at the top of Zipp's lineup, and it earns that position through a set of capabilities that begins with the rim and extends through the hub, the tire interface, and the connection to your phone via SRAM AXS. This is not a wheel for every rider. For the rider it suits, there is nothing else in the Zipp catalog that comes close.

Sawtooth Rim: Hyperfoil, HexFin, and an Undulating Profile

The 353 NSW uses Zipp's Sawtooth rim design, which means the rim depth is not uniform around the circumference. The profile undulates between 35mm and 40mm as you move around the rim, creating an aerodynamic effect that differs fundamentally from a standard fixed-depth rim. This is not a compromise — Zipp's wind tunnel testing showed that the undulating Sawtooth profile delivers crosswind stability advantages that a flat-profile rim at the same average depth cannot match, because the varying surface geometry interacts with crosswinds differently at different points of the rotation. The Sawtooth shape also allows the rim to be lighter than an equivalent fixed-depth construction at the same structural integrity.

Two additional technologies work alongside the Sawtooth profile. Hyperfoil nodes are shaped protrusions on the rim surface that act as aerodynamic vortex generators, conditioning airflow as it moves over the rim. HexFin ABLC (Aerodynamic Boundary Layer Control) dimples cover the rim surface and reduce aerodynamic drag by managing the boundary layer of air closest to the rim. The combination of these three elements — undulating depth, Hyperfoil nodes, and HexFin ABLC dimples — represents the current state of Zipp's aerodynamic rim engineering. A revised carbon layup on the current 353 NSW also delivers more than 16 percent higher rim impact strength compared to the previous generation without adding weight.

AXS Wheel Sensor: Tire Pressure Monitoring Built In

The 353 NSW is the first SRAM AXS-connected wheel. The rim is designed to seamlessly integrate the Zipp AXS Wheel Sensor, which monitors tire pressure in real time without a separate device mounted to the valve stem. Before a ride, a green indicator confirms the pressure is within the target range. During the ride, the sensor reports pressure data through the SRAM AXS ecosystem. This is relevant because tubeless tire pressure is not static — temperature, altitude, and distance affect it — and pressure directly affects rolling resistance, grip, and puncture resistance. The 353 NSW makes fine-tuning tire pressure on a per-ride or mid-ride basis practical in a way that traditional setups do not.

ZR1 SL Hub: Ceramic Bearings, 66 Points of Engagement

The 353 NSW front wheel runs Zipp's ZR1 SL hubset with custom hybrid ceramic bearings. Ceramic bearings run at lower friction than steel alternatives under load, particularly in the conditions where road wheels operate — high rotational speeds with varying loads. The ZR1 SL hub is also 30 grams lighter than the hub used in previous-generation NSW wheels. The front hub runs on custom hybrid ceramic bearings sized specifically for the 353 NSW application. The 24-spoke front wheel uses a Centerlock rotor interface and is compatible with any disc brake thru-axle fork using a 12x100mm standard.

Tubeless Setup and Tire Compatibility

The 353 NSW uses a hookless rim design. Hookless rims are tubeless-only — clincher tires with inner tubes are not approved for use on this rim. The 25mm internal width and 30mm external width are optimized for 30mm tires, and the approved tire size range is 29mm to 35mm ISO/TSS compatible tubeless tires. Maximum tire pressure is 73psi. Running tires at or below this limit on a hookless rim is a design requirement, not a preference. The 353 NSW is not approved for gravel riding. For riders already committed to tubeless road setups in the 28-32mm tire range, the hookless system is a non-issue. For riders who run narrower tires or prefer clincher backup, it is a meaningful constraint to know before buying.

The Zipp 353 NSW carries a lifetime warranty and is sold here as the front wheel. The matching rear wheel is available separately. Driver body compatibility on the rear covers SRAM XDR and SRAM/Shimano Road; Campagnolo driver body is sold separately for the rear.
