The Industry Nine Hydra Classic front hub brings the same obsessive in-house manufacturing that defines I9's rear hubs to the front wheel — every shell, axle, and endcap machined from 7075-T6 aluminium bar stock in Asheville, North Carolina. The result is a front hub that's exceptionally light, stiff, and serviceable without proprietary tools.

  • 0.52° engagement — one of the fastest engagement angles available in any hub
  • Machined in-house from 7075-T6 aluminium for exceptional stiffness and low weight
  • 32-hole drilling suits most trail and enduro front wheel builds
  • Boost 15x110mm axle standard for maximum fork compatibility
  • 6-bolt (ISO) disc rotor mount
  • Tool-free serviceability — no proprietary gear required

Industry Nine controls every stage of production — turning and milling bar stock, wire EDM cutting A2 tool steel pawls and driverings, and applying anodisation — all on the same premises. That vertical integration is why Hydra hubs are so consistent and why spare parts are always available.

Fits 15x110mm Boost front forks. 6-bolt (ISO) disc mount. 32H for pairing with most standard rim drillings.
