Building upon a long legacy of reliable hubs, Industry Nine evolves once again with the Hydra - an all new series of hubs that replaces the successful Torch series. Most impressively, the Hydra rear hub boasts a seemingly impossible 690 points of engagement - that's one click for every 0.52° rotation. Industry Nine was already ahead of the pack with their Torch Classic hub at 120 points of engagement - Chris King has 72. Hydra has almost 600% more than previous gen Torch hubs; let there be zero doubt in your mind that there isn't any with a more satisfying hum. While the Torch Classic sounded reminiscent of a dozen hornets following you, the Hydra is more like an entire hornets nest on your tail, and they are angry!
So how exactly did Industry Nine accomplish the task of packing in 690 engagement points? The innovative new design utilizes a continually phased six-pawl system, creating a procession of engagement points between pawl and drivering. In a new implementation of the pawl system, Hydra utilizes the inherent flex of the axle to accomplish positive second, third or fourth pawl contact, ensuring that there is always instantaneous, solid transmission of power from your legs to your pedals. Not only does this design offer unprecedented pawl engagement, it also creates a system that is able to account for the forces and pressures that a hub encounters, dispersing them throughout the hub's components. This results in longer lasting bearings and decreased drag in the system.
All Industry Nine hubs are precision-built right at home in the USA at their Asheville, North Carolina factory.
