Coast to coast.

The Zipp Cognition NSW Freehub Kit is the ultimate in Zipp hub technology. Every time a conventional hubset starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. The drag between hub shell and driverbody during coasting is considered as efficiency loss, especially for road wheels. High drag also can significantly contribute to chain-dropping issues. The drag torque drives the cassette clockwise so the chain gets loose on the load side.

The solution? The rear Cognition™ hub with AxialClutch™ technology reduces drag by disengaging the ratchet mechanism when coasting. It then uses magnets to re-engaged once the rider starts pedaling.

Includes pre installed bearings and freehub seal.
