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

Built from the ground up with feedback from thousands of Hydra hubs, the Hydra 2 is engineered to endure the harshest trails while delivering unprecedented engagement and reliability. A 65% thicker axle, larger 6903 bearings, and redesigned pawl pockets reduce wear and drag, so you stay in control when the terrain gets brutal. Whether you’re chasing speed on technical climbs or pushing through rough downhill sections, this hub translates power into predictable, immediate response with every pedal stroke.

Its telepathic engagement and robust construction mean you can ride with confidence across wet rock, loose gravel, and roots without worrying about slippage or stall. The result is a wheel that feels fast, responsive, and unflinchingly durable mile after mile.

Who is this for?

Riders who demand durable, precise performance from their wheelset — including trail, enduro, and downhill riders, plus riders running full-power ebikes — and who value a proven, long-lasting freehub experience that won’t slip under pressure.

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