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

The Hydra 2 rear hub delivers precision where it matters most: on steep climbs, fast descents, and rough singletrack. With a reinforced 65% thicker axle, larger 6903 bearings, and labyrinth seals, it maintains smooth power transfer no matter how dirty or aggressive the ride gets. The freehub engages every 0.41 degrees with an 870 P.O.E., delivering telepathic control that makes line choice and tempo feel natural—even on full-power ebikes.

Who is this for?

Ideal for riders who demand durable, high-engagement hubs that can survive long seasons of hard riding, including trail, enduro, downhill, and ebike setups. If you value reliability, low drag, and consistent performance when you need it most, this hub is for you.

Each item is professionally packed and shipped next day. Select in-store pick-up at checkout and visit us if you are local!
