Industry Nine Hydra 2 Classic Rear Hub - 12 x 148mm 6-Bolt Micro Spline Silver 32H

On demanding trails, reliability and precise power transfer are non-negotiable. The Hydra 2 re-engineers a proven hub into a bombproof rear that thrives on enduro descents and full-throttle e-bike power, with a 65% thicker axle, larger 6903 bearings, and a freehub that engages every.41 degrees for telepathic control. Designed for trail, enduro, and downhill riders who demand lasting performance under the harshest conditions.

Who is this for?

Riders who push beyond mellow climbs and smooth singletrack—enduro racers, aggressive trail riders, and e-bike enthusiasts seeking durable, low-maintenance hardware that delivers immediate engagement and reliable power transfer on every ride.
