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

Built for the most demanding terrains, the Hydra 2 re-engineers durability and engagement so you can ride with confidence when the pace heats up. With a 65% thicker axle, larger 6903 bearings, labyrinth seals, and enlarged pawl pockets, this hub resists grit and load through long days on trail, enduro, and downhill runs. The 0.41-degree engagement on the Hydra 2 Freehub body delivers near-telepathic response when you crack the throttle, keeping you in control even under full power.

Who is this for?

Trail, enduro, and downhill riders who demand durable performance on rough terrain, plus riders powering high-output e-bikes, will appreciate the Hydra 2’s robust axle, sealed bearings, and precise engagement. If you value predictable acceleration and smooth operation with less drag across long rides, this hub is built for you.
