Cassette to Driver
 

I have an eastern with the stock hub/cassette and was wondering if it is possible to put another driver on to change it from 12T to 9T without buying a whole new hub.

Is it possible for other hubs? Yes. For that hub, I believe not.

Alright thanks.

The eastern stock back wheel on the element is disgraceful. I bent my axle, flatspotted the rim 3 times, buckled the the rim, the bearings were shot. If yours is anything like mine was gget a new wheel. I got an oddessy hazard, best desision i ever made.
