Industry Nine Hydra 2 Front Hub / 6-Bolt / 28H / 15 x 110

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.

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.

Our new axle design is 65% thicker with an improved stress washer design.

Larger, 5.5mm pawl pockets that evenly distribute force 26% better, preventing deformation of the pockets over years of use.

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.

Full-contact radial lip seals paired with proximity dust shields keep grit and grime out, and lubrication in.

Durable 6903 bearings are used throughout for smooth, long-lasting performance.

Officially known in-house as our system chassis, Hydra2 refines our direct-thread, straight-pull hub and spoke system. Both front and rear hubs, along with each spoke, can be individually customized in any of our 12 anodized colors.
