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

Built for aggressive trail riding and enduro adventures, this Hydra 2 hub blends Industry Nine’s legendary durability with precise engagement that responds to every pedal stroke. A thicker axle and larger bearings stand up to the punishment of long descents and full-power e-bikes, while redesigned pawl pockets reduce wear and drag. The result is predictable, telepathic control when you need it most, even in muddy, rocky sections.

Who is this for?

Riders who demand dependable, high-engagement hubs for trail, enduro, or downhill biking, including riders on powerful e-bikes, will appreciate Industry Nine’s robust build and precise feel. If you want a hub that delivers instant engagement, lasting durability, and a lighter, stronger shell for aggressive riding, this is for you.
