Zipp 454 NSW Wheelset

No, the Zipp 454 NSW wheels feature a hookless rim design that is strictly for tubeless-ready tires. You must use tubeless tires, though you can run them with or without sealant depending on your setup preference.

The maximum tire pressure for this wheelset is 73 psi. Because of the hookless rim design, it is critical not to exceed this limit to ensure the tire remains safely seated on the rim.

The undulating Sawtooth profile, combined with Hyperfoil nodes, is specifically designed to manage airflow around the rim. This helps reduce the side force felt in gusty conditions, making the bike feel more stable and predictable compared to standard deep-section wheels.

No, the Zipp 454 NSW is designed exclusively for disc brake systems using a Center Lock rotor interface. They are not compatible with traditional rim brake setups.

The maximum system weight limit, which includes the rider, the bike, and all gear, is 114 kg (250 lbs). This limit ensures the structural integrity and performance of the carbon construction.

The Cognition V2 hub utilizes Axial Clutch V2 technology, which reduces drag when you are coasting. It allows the ratchet mechanism to disengage completely while freewheeling, resulting in a quieter and more efficient ride.
