Industry Nine Classic hubs are the heart of your wheelset; everything revolves around them, literally. Every Classic mountain hub is made from start to finish in our Asheville, NC, machine shop. From turning and milling bar stock 7075-T6 aluminum for shells, axles, and endcaps, wire EDM cutting A2 tool steel for pawls and driverings, to our in-house anodization lab, every design step, 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 compatible.

Materials
Berd spokes are made from an advanced polymer called ultra high molecular weight polyethylene (UHMWPE). UHMWPE has 12 times the strength-to-weight ratio of steel and floats on water. Berd spokes have an improved fatigue life over steel and are impervious to the elements. This is what makes Berd spokes the lightest, strongest, and most durable spokes ever invented.
