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

Built to withstand the rough realities of trail, enduro, and downhill riding, the Hydra 2 reinvents durability with a thicker 65% axle and larger 6903 bearings. Its labyrinth seals and enlarged pawl pockets deliver bombproof reliability under aggressive riding and full-power Ebike abuse, while refined drive ring and increased pawl tooth counts reduce drag and increase engagement for a telepathic burst of control.

Designed for riders who crave unwavering performance in challenging terrains, this rear hub combines Industry Nine’s legendary balance of strength and lightness. With 6-bolt disc compatibility, Micro Spline cassette support, and J-Bend spokes, it’s tuned for serious riders who demand confidence from every pedal stroke.

If you value long-term durability, low drag, and a hub that stays quiet and dependable ride after ride, this Industry Nine Hydra 2 is built for you.
