PROPER Magnalite Rear FEMALE Cassette

The Proper Microlite Magnalite Rear Cassette Hub - features a new 'shim' system to replace the driver bearings, which they claim virtually eliminates the possibility of failure. As well as a heat treated axle and a CNC machined Hub shell this is a very trick hub. Coming with a 9t cassette body as standard and quality bearings this hub should last along time.
