Industry Nine Hydra2 MTN 32H Classic Rear Hub ISO 6-Bolt Blue 12x148

Enhancing our top-performing trail, enduro, E-bike, and DH hub, we prioritized durability by methodically removing potential failure points based on data from over 100,000 Hydra hubs worldwide. The axle is now 65% thicker and engineered to better distribute stress. It includes larger 6903 bearings, along with a new labyrinth channel and a full-contact radial lip seal to prevent contaminants that accelerate bearing wear. Additionally, an improved design guarantees consistent bearing preload, unaffected by differences in axle tightness.

Featuring larger 5.5mm pawl pockets that improve force dispersion by 26%, this design resists stretching and elongation over extended use. The drivering is constructed from tougher metal and includes an additional tooth on each pawl, ensuring the Hydra2 withstands the torque demands of the most powerful e-bike motors. Building on the strength and reliability of our premier trail, enduro, E-bike, and DH hub, durability has been further enhanced by addressing known failure points based on data from over 100,000 Hydra hubs worldwide. The axle is now 65% thicker and redesigned to more effectively distribute stress. Equipped with larger 6903 bearings, a new labyrinth channel, and a full-contact radial lip seal, it defends against contaminants that cause premature bearing wear. A refined mechanism also ensures consistent bearing preload regardless of axle tightness variations.

The result is a hub that can shrug off extreme use by the most demanding riders.

Here’s how we achieved it:

Designed to be exceptionally durable and high-performing, the Hydra2 hub delivers a rapid 0.41° engagement and reduces coasting drag by 60% compared to its predecessor. Featuring Industry Nine’s signature direct thread hubshell and precisely machined aluminum spokes, this hub system offers an advanced blend of strength, precision, and aesthetics. Engineered by some of the cycling industry’s leading innovators, Hydra2 stands as the ultimate choice for riders, bikes, and trails that demand top-tier hub performance.
