Industry Nine Classic hubs are the heart of your wheelset, everything revolves around them, literally. Every Classic mountain hub is made start to finish in our Asheville, NC machine shop. From turning and milling bar stock 7075-T6 aluminum for shells, axles and encaps, wire EDM cutting A2 tool steel for pawls and driverings, to our own in-house anodization lab, every step of design, engineering, manufacturing and assembly is done on premises to our exacting standards.
Hydra Classic mountain hubs are loaded with features every rider will appreciate such as revolutionary 0.52° engagement, generously low weights and an intuitive layout that can be serviced without any proprietary tools. Our range boasts a universe of standard options in terms of axle fit, spoke hole drillings, disc rotor mounting, freehub bodies, and colors. E-bike Class 1 compatible.
Warranty
ALLOY PRODUCT WARRANTY
We offer a two-year warranty against defects in materials or workmanship on all Industry Nine products. Industry Nine will repair or replace, at our discretion, any affected components or assemblies. The warranty will apply to stems, MatchStix, hub shells, axles, drive mechanisms, spokes, and rims.
The intended application of Industry Nine products are single rider bicycles. Industry Nine will not be able to provide warranty support or assume liability for hubs or wheels that are utilized outside of their intended purpose. This warranty covers materials and workmanship but does not cover normal wear and tear, such as bearing wear, or damage due to lack of proper service intervals.
Spokes will be warranted against defects, but not trail accidents, drivetrain/frame mechanical failure, or foreign object intrusion.
Aluminum rims are covered under the two-year warranty but are not warrantied for impact or crash damage. Use of non-authorized aftermarket adaptors and/or modification of axles, hubs, spokes or any other component may result in a voided warranty. Modification of rim finish or graphics by use of stripping solvents or chemicals will void rim warranty.
We believe in our product and will try to give Industry Nine customers the benefit of the doubt in any case where the cause of failure is undetermined.
