Description
Industry Nine Hydra 2 6B Rear Hub
The Industry Nine Hydra 2 6B Rear Hub represents the next evolution of precision and performance in hub engineering. Completely reimagined from the ground up, Hydra 2 builds on the proven legacy of over 100,000 original Hydra hubs with major structural and mechanical enhancements.
At its core, a newly designed 65% thicker axle boosts stiffness and strength, while larger 6903 bearings with advanced labyrinth seals ensure smooth rotation and exceptional longevity, even in the harshest conditions. Enlarged pawl pockets and reinforced internals add unmatched durability, making the Hydra 2 a true workhorse for aggressive riders and demanding terrain.
Performance has also been elevated with a refined drive ring and an additional tooth per pawl, delivering lightning-fast 0.41° engagement — translating every ounce of pedal input into forward motion with minimal drag.
Optimized for 6-bolt brake rotors, the Hydra 2 6B rear hub is the perfect blend of engineering precision, durability, and efficiency, setting a new benchmark for mountain bike hub technology.
