For the next generation of riders, bikes, and trails that demand the very best, Hydra2 is the pinnacle of hub performance.

To make their most advanced trail, enduro, E-bike, and DH hub even better, Industry 9 have put durability at the forefront, systematically eliminating potential failure points using data gleaned from the 100,000+ Hydra hubs in use around the world.

• 65% thicker axle. 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 can cause premature bearing wear.
• A new design to ensure consistent bearing preload, regardless of variations in axle tightness.
• Larger, 5.5mm pawl pockets that dissipate force 26% better, preventing stretching and elongation of the pockets.
• Tougher drivering metal and an extra tooth on each pawl, guaranteeing Hydra2 can easily handle the torque of the most powerful ebike motors.

The result is a hub that can shrug off extreme use by the most demanding riders. A hub system with brains, brawn, and beauty — a piece of rideable art built by some of the most innovative engineering minds in the cycling industry.
