Zipp 353 NSW Carbon Tubeless Disc Brake Wheel

The Zipp 353 NSW Carbon Tubeless Disc Brake Wheel combines low weight, aerodynamic performance and wide-tire efficiency in a premium road wheel designed for climbing, endurance riding and fast racing.

This generation of the 353 NSW uses Zipp's distinctive 45mm Sawtooth™ rim profile, a 25mm internal hookless carbon rim and Cognition V2 hub technology to balance speed, crosswind stability and low rolling resistance.

45mm Sawtooth Carbon Rim

The 353 NSW uses Zipp's distinctive Sawtooth rim profile with Hyperfoil nodes, creating an undulating 45mm-deep carbon rim.

The shape is designed to combine aerodynamic efficiency with predictable handling in crosswinds while keeping rim weight low for climbing and rapid acceleration.

This makes the 353 NSW well suited to riders who want one premium carbon wheel platform for fast road riding across changing terrain.

Total System Efficiency

Zipp developed the 353 NSW around its Total System Efficiency (TSE) approach.

Rather than focusing on aerodynamics alone, TSE addresses multiple sources of resistance, including:

• Aerodynamic drag

• Rolling resistance

• Gravity

• Vibration losses

The result is a wheel designed to deliver efficiency across climbs, descents, rough pavement and fast rolling terrain.

25mm Internal Hookless Rim

The carbon rim uses a 25mm internal width with a hookless / Tubeless Straight Side design.

The wider internal profile is designed around modern road tires and lower tire pressures, helping improve comfort, grip and rolling efficiency.

Zipp lists a maximum tire pressure of 73 psi / 5.0 bar for this rim platform. Always follow Zipp's current tire compatibility guidance when selecting and installing tires.

Cognition V2 Hub

This generation of the 353 NSW uses Zipp's Cognition V2 hub system.

The rear hub incorporates the Axial Clutch V2 mechanism, designed to reduce friction while coasting while providing responsive engagement under power.

The Cognition V2 system was developed specifically for Zipp's premium NSW wheel range and combines low drag with serviceable internal components.

Tubeless Road Performance

The 353 NSW uses a carbon hookless tubeless rim designed specifically for compatible tubeless road tires.

Running an appropriate tire at optimized pressure can improve rolling efficiency, grip and ride comfort, particularly over rough road surfaces.
