HYDRA2 32 hole Classic Rr Hub ISO 6 Bolt
Tax included.
To make our most advanced trail, enduro, E-bike, and DH hub even better, we put durability at the forefront, systematically eliminating potential failure points using data gleaned from the 100,000+ Hydra hubs in use around the world.
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.
A new, foolproof 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 over years of use.
Tougher metal for the drivering 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.
Here’s how we achieved it:
In our effort to make the Hydra2 hub bomb-proof, bullet-proof, and Brandon-proof, we didn’t compromise on meaningful performance gains, and the next generation has both quicker 0.41° engagement and 60% less coasting drag than its predecessor.
Combine I9’s trademark direct thread hubshell and machined aluminum spokes, and you’ve got 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.
For the next generation of riders, bikes, and trails that demand the very best, Hydra2 is the pinnacle of hub performance.
