Industry Nine Hydra 2 Classic Rear Hub - 12 x 157mm 6-Bolt Micro Spline BLK 32H

Built for aggressive riders who demand reliability on gnarly climbs and fast descents, this Hydra 2 rear hub delivers instant, precise engagement when the trail turns harsh. The redesigned 65% thicker axle, larger 6903 bearings, and labyrinth seals defend against grit and power-sapping wear, so your bike stays responsive longer. With 870 P.O.E and enlarged pawl pockets, you get instant drive under load with minimal drag, even on full-power e-bikes.

Who is this for?

For trail and enduro riders who demand durability, precise engagement, and confidence when the terrain turns technical. If you ride full-power e-bikes or aggressive builds and want a hub that stays smooth, quiet, and reliable ride after ride, this 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!
