Our most sophisticated trail, enduro, E-bike, and DH hub has been enhanced with a focus on durability, drawing on data from over 100,000 Hydra hubs in operation globally. It features a 65% thicker axle redesigned for improved stress distribution, upgraded larger 6903 bearings throughout, and a new labyrinth channel combined with a full-contact radial lip seal to prevent contaminants that accelerate bearing degradation.
This redesigned hub features a reliable system that maintains consistent bearing preload despite axle tightness variations. It incorporates larger 5.5mm pawl pockets that distribute force 26% more effectively, reducing the risk of stretching and elongation over time. With a stronger drivering metal and an additional tooth on each pawl, the Hydra2 is engineered to withstand the high torque of powerful e-bike motors. The outcome is a hub built to endure the toughest conditions faced by serious riders.
Here’s how we achieved it:
In our pursuit to make the Hydra2 hub exceptionally durable, we maintained significant performance improvements, including a faster 0.41° engagement and 60% reduction in coasting drag compared to the previous model. Featuring I9’s signature direct-thread hubshell and precisely machined aluminum spokes, this hub system combines advanced engineering, strength, and refined design. Built by leading experts in cycling technology, Hydra2 represents the highest standard of hub performance for the most demanding riders, bikes, and trails.
