Two things you already know and love, combined in one wheelset. The lightning-fast drive from the Hydra V2 Classic hubs combined with our all-terrain Enduro S alloy rim creates a wheelset for technical trails. The perfect upgrade for any mountain bike built for demanding terrain with long descents.

Industry Nine Hydra V2 hubs are the heart of your wheelset, everything revolves around the hub, literally. Every Classic Mountain hub is made in Asheville, NC. From turning and milling 7075-T6 aluminum bar stock for shells, axles and capsules, to wire EDMing A2 tool steel for pawls and drivers, to our in-house anodizing lab, every step of design, engineering, manufacturing and assembly is done on site to our exacting standards.
