Industry Nine Hydra Classic Rear Hub - 12 x 148mm 6-Bolt XD Purple 28H

When your ride hinges on instant, predictable engagement, the Hydra Classic rear hub answers the call. Built start to finish in Asheville, NC, Industry Nine crafts every detail—from turning and milling 7075-T6 aluminum shells to in-house anodization—so power transfer feels instant and confident. The 690 P.O.E. Hydra Freehub body engages every 0.52 degrees, delivering near-telepathic control, while six pawls and six-phase engagement with a 115-tooth driver ring ensure precise, reliable response on technical climbs and fast descents alike. Designed to keep you in the saddle and out of the service queue, this hub blends rugged durability with a premium purple finish for standout trail presence.

Who is this for?

This hub is built for riders who demand meticulous engineering, long-term reliability, and effortless maintenance. It suits wheel builders and serious riders upgrading a 12 x 148mm, 6-bolt-disc wheelset who value precise power transfer, easy servicing with standard tools, and a bold purple aesthetic that stands out on the trail.
