Industry Nine Hydra 2 Classic Rear Hub - 12 x 148mm 6-Bolt Micro Spline Orange 28H

On demanding trails, reliability isn’t a luxury—it’s a must. Hydra 2 re-engineers the rear hub with a 65% thicker axle, larger 6903 bearings, labyrinth seals, and bigger 5.5mm pawl pockets to absorb hard hits and keep rolling smoothly. The 6-pawl Hydra 2 freehub body engages every 0.41 degrees for telepathic control, delivering consistent power transfer on enduro descents and full-power e-bikes, with less drag and more confident, precise engagement.

Who is this for?

This hub is built for riders who push hard on technical trails, enduro routes, and downhill sessions, and for riders with high-power e-bikes who demand maximum durability and smooth engagement. If you value long service life and precise, drop-in performance, 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!
