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.


Berd spokes are made from an advanced polymer called ultra-high molecular weight polyethylene (UHMWPE) that has 12 times the strength-to-weight ratio of steel and floats on water. Berd spokes have an improved fatigue life compared to steel and are impervious to the elements.
