This is a SE Racing replacement rear axle for Blocks Flyer hubs. The threads are 3/8" x 26tpi. The axle is 165mm long and constructed of chromoly steel. The shoulder width is approx. 72mm, and it works with cartridge bearings that have a 10mm ID. Included is a set of 6000-2RS bearings and lock nuts.
This is intended to fit the SE Blocks Flyer rear hubs. This may work with some other hubs, but you must measure your old axle to make sure.
