Description

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.

Easy to replace

My 303 NSW wheel set was for Campy and I needed SRAMShimano. I bought the Zipp freehub kit, but dont forget to get the SRAMShimano axle end cap, too. I would have given it 5 stars if BTD.com would have told me I needed it.

Great Component

Does what it's supposed to do with no fuss. The best thing I can say is that I never think about this "unsexy" part of my wheels. I can think of no better praise for something so fundamentally functional.
