Industry Nine Hydra 2 Classic 12x148mm 32H Rear Hub
INTRODUCING THE NEXT GENERATION OF HYDRA
Industry Nine has redefined durability with the Hydra 2—the evolution of their most advanced trail, enduro, E-bike, and DH hub. Drawing from real-world data across 100,000+ Hydra hubs, they’ve meticulously strengthened every component, eliminating potential failure points to create their toughest hub yet.
But toughness doesn’t come at the cost of performance. Hydra 2 delivers an ultra-responsive 0.41° engagement, reduces coasting drag by 60%, and features a scalloped hubshell design that reinforces high-stress zones while trimming excess material elsewhere. The result? A hub that’s engineered for maximum strength, efficiency, and resilience under extreme forces—all while maintaining its signature aesthetic.
For the next generation of riders, bikes, and trails that demand the very best, Hydra 2 is the pinnacle of hub performance.
Anodizing: All hub brands we sell offer at least one anodized color, and although they use purpose-built anodizing labs, there can be variations in color due to the nature of the electrochemical process. As such, we cannot guarantee that your hubs will match in color exactly as pictured on our website. If we notice a significant difference in a pair of hubs you order, we will contact you to discuss a resolution. If you have any questions, feel free to send us a message.
Features
- A 65% thicker axle that’s been redesigned to dissipate stress more effectively
- Larger 6903 bearings throughout, and a new labyrinth channel and full-contact radial lip seal to keep out elements that cause premature bearing wear
- A new, foolproof design to ensure consistent bearing preload, regardless of variations in axle tightness
- Larger, 5.5mm pawl pockets that dissipate force 26% better, preventing stretching and elongation of the pockets over years of use
- Tougher metal for the drivering and an extra tooth on each pawl, guaranteeing Hydra 2 can easily handle the torque of the most powerful E-bike motors
- Quicker 0.41° engagement (870 points of engagement!) and 60% less coasting drag than the old Hydra
- New scalloped hubshell minimizes material in low-stress areas while enhancing durability where it matters most
