Industry Nine Hydra 2 DH-S Features

- Larger 6903 bearings throughout, and a new labyrinth channel and full-contact radial lip seal to keep out elements that cause premature bearing wear
- Quicker 0.41° engagement and 60% less coasting drag than its predecessor
- A new, foolproof design to ensure consistent bearing preload, regardless of variations in axle tightness
- Larger, 5.5mm pawl pockets that distribute force 26% better, preventing deformation of the pockets over years of use
