When the trail takes a steep dive and every split second matters, the Hydra2 DH 6-Bolt Wheelset is your ultimate ally. Built for tough descents, its high-volume, reinforced rim helps you stay steady on even the roughest terrain. The oversized hollow bead wall guards against pinch flats, while the rugged straight-pull aluminum spokes deliver bombproof reliability, so you can focus on the ride and let gravity take care of the rest.
Industry Nine Hydra 2 DH 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
