Leveraging insights from over 100,000 Hydra hubs in operation worldwide, we've enhanced our top-tier trail, enduro, E-bike, and DH hub with durability as a key focus. The axle is now 65% thicker and reengineered for improved stress distribution. It features larger 6903 bearings and incorporates a new labyrinth channel along with a full-contact radial lip seal to protect against contaminants that lead to early bearing degradation.
Featuring a new, fail-safe design that maintains consistent bearing preload despite axle tightness variations, this hub incorporates larger 5.5mm pawl pockets that improve force distribution by 26%, reducing wear and elongation over time. The drivering is crafted from stronger metal and includes an additional tooth per pawl, ensuring the Hydra2 withstands the high torque produced by powerful e-bike motors. This results in a hub built to endure the rigorous demands of the most intense riders.
Here’s how we achieved it:
Designed to be incredibly durable without sacrificing performance, the Hydra2 hub offers faster 0.41° engagement and 60% less coasting drag than its predecessor. Featuring Industry Nine’s signature direct-thread hubshell and precision-machined aluminum spokes, this hub combines advanced engineering with robust strength and refined aesthetics. Built by leading experts in cycling innovation, the Hydra2 sets a new standard for riders, bikes, and trails that require the highest level of hub performance.
