Designed to conquer technical singletrack while striking the ideal balance of weight, durability, and value, the Hydra2 Trail 6-Bolt Rear Wheel is ready for all-day adventures. Its alloy rim, featuring a wide, hollow bead wall, guards against pinch flats, and Hydra2’s near-instant engagement gives you a quick burst out of corners and up climbs. With i9’s rugged straight-pull aluminum spokes, this wheel is a no-compromise choice, built to handle long hours in the saddle without fail.
Industry Nine Hydra 2 Trail Features
- A 65% thicker axle that’s been redesigned to dissipate stress more effectively
- 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
- Tougher metal for the drive ring and an extra tooth on each pawl, guaranteeing Hydra2 can easily handle the torque of the most powerful e-bike motors
