Two things you already know and love, combined in one wheelset.
The lightning-fast drive from the Hydra Classic hubs in combination with our all-terrain Enduro S alloy rim creates a wheelset for technical trails.
The perfect upgrade for any mountain bike built for challenging terrain with long descents.
Industry Nine Hydra hubs are the heart of your wheelset, it’s all about 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 EDM of A2 tool steel for pawls and carriers, to our in-house anodizing lab, every step of design, construction, manufacturing, and assembly is performed to our exacting standards on-site.
