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.
More rolling resistance in a hub comes from seals protecting the hub from the elements. We've optimized all the seals in Hydra2 to minimize friction.
65% Thicker Axle Our new axle design is 65% thicker with an improved stress washer design.
Oversized Pawl Pockets Larger, 5.5mm pawl pockets that evenly distribute force 26% better, preventing deformation of the pockets over years of use.
With .41 degree engagement and 60% less coasting drag than Hydra, Hydra2 provides intantaneous response and descends faster than ever.
Drive Ring We used an updated and more fatigue resistant steel for the drive ring and increased the pawl tooth count to 3, guaranteeing Hydra2 can easily handle the torque of the most powerful ebike motors.
Designed specifically for trail, enduro, and downhill riders with the strength to handle full-power ebikes, Hydra2 blends precision machining, local manufacturing, and the rider driven ethos you’ve come to expect from Industry Nine.
PRECISION EVOLVED We listened to your feedback from over 100,000 Hydra hubs ridden worldwide. Through relentless refinement Hydra2 emerges as the most versatile, high performance hub and wheel system available today.
Rider confidence begins with knowing your components can keep up with every challenge. After years of rigorous development and extensive real-world testing, we’re proud to say Hydra2 is engineered to reliably perform in the toughest riding conditions.
Scalloped flanges on Hydra2 j-bend hubs increase overall strength, and remove excess material for a lighter, stronger hubshell.
