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

On demanding trails, you need a hub you can trust to stay quiet, smooth, and relentlessly reliable. The Hydra 2 combines a thicker 65% axle, larger 6903 bearings with labyrinth seals, and enlarged pawl pockets to deliver bombproof durability and lightning-fast engagement every 0.41 degrees. It’s built for trail, enduro, downhill, and even full-power e-bikes, so you can ride with confidence no matter the terrain.

Who is this for?

Riders who push the pace on technical singletrack, downhill runs, or that power-sipping e-bike setup—those who value strong, precise engagement and long-lasting durability over quick fixes.

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