Product Description


All purpose MTB sealed bearing rear cassette Disc hub.
Light enough for Cross Country, rigid enough for Freeride, buff enough for DH.

The Spin Doctor rear disc hub uses a bolt-on ball bearing cassette body with an integrated 3 pawl positive engagement drive. This places the 2 main hub sealed bearings on the outside of the hub (beyond the cassette body), providing superior axle support.

The "outboard bearing" construction reduces axle flex and thus reduces bearing wear.
When bolted together, the cassette and hub body become a strong, integrated unit, with 2 sealed cartridge main hub bearings and integrated Freehub looseball bearings.

Sweeping shell styling and minimalist type International Disc mounts provide a beautiful looking, strong, light, rear MTB hub.

Wheels Guide

What are wheels?

Wheels are probably the second most important part of your bike, after the frame. A lot of the bike’s riding characteristics come from its wheels.

Who needs wheels?

A wheel upgrade can make a massive difference to your bike. Because of this, you might consider a new set of wheels, even if the old ones aren’t worn or damaged.

What are the choices?

Mountain bikers choose their wheels in 26in, 27.5in or 29in size, depending on what their frame is built for. Road bike wheels are 700c. Beyond this, there’s a dizzying array of rim material and depth, spoke type and hubs galore – enough to make your head spin faster than your wheels.

What should I buy with them?

A wheel upgrade always deserves a lovely new set of tyres. These too have a massive impact on how your bike rides.

Anything else?

There are several approaches to buying wheels – you can buy a full wheelset, for perfect pairing, or you can take a modular approach, picking hubs and rims before having a new set built to your specification.
