Kasai FS Dynamo HUb 15mm X 100 Through Axle Center Lock Disc

Most dynamo hubs are sealed at the factory and cannot be repaired by the road side or in a bike shop. These hubs need to be cut off the wheel and must be sent back to the factory. Not with the Kasai FS Dynacoil. The bearings and the entire coil assembly of the Kasai FS can be replaced using two simple tools.
