Description
The Industry Nine Hydra2 Single Speed Rear Hub in silver offers high-quality performance designed specifically for single-speed setups.

The Hydra2 freehub mechanism has been improved with larger pawl pockets and a stronger metal drive ring for enhanced durability. It uses a 6-pawl, 6-phase system with an extra tooth on each pawl, resulting in a quick engagement angle of 0.41 degrees. The hub includes a 6-bolt, 44mm BCD International Standard disc mounting interface. It has 32 spoke holes, fits a 10x135mm bolt-on rear axle, and is designed for use with J-bend spokes.
