Why We Like The Hydra Classic Rear Boost Centerlock Mountain Hub

When we're building up our next dream wheelset, Industry Nine Hydra hubs are typically our first choice thanks to their outstanding performance and eye-catching colorways. Offering an 0.52-degrees between engagement points, the Hydra's accelerate instantaneously when we put power to the pedals—responsiveness that most hubs simply cannot match. They're built completely in-house at Industry Nine's North Carolina facility, ensuring quality is preserved at each and every production step.
