Shimano Dura Ace track racing hub. Rear only, 36 hole, NJS 110mm spaced type.
The hub is double sided, high flange, with very fast, loose open bearings.
This is the 110mm spaced version with cut axles that have an 8mm width to fit in 110/8mm Japanese
keirin frames. These are very rare hubs, and rarely available outside Japan.
This is the proper way to build a rear wheel for your keirin frame, although some mechanics like to grind down the ends to 10mm, and stretch the ends out! :(
