Hubs

The Shimano HB-M525A hub is ideal for use with 6-bolt disc brake rotors and quick release dropouts.
- Double contact sealing
- Super polished bearing races for low friction rolling
- 6-bolt ISO disc mounting surface

Shimano's Dura-Ace Track Hi-Flange Hubs build up into stiff, fast spinning wheels that want to sprint right out off the line. Stainless steel bearings and Borozon treated bearing races minimize drag for maximum efficiency and speed.
