Introducing the Next Generation of HYDRA
To make our most advanced trail, enduro, E-bike, and DH hub even better, Industry Nine put durability at the forefront, systematically eliminating potential failure points using data gleaned from the 100,000+ Hydra hubs in use around the world.
 Scalloped flanges on Hydra2 j-bend hubs increase overall strength, and remove excess material for a lighter, stronger hubshell. |  With .41 degree engagement and 60% less coasting drag than Hydra, Hydra2 provides intantaneous response and descends faster than ever. |  More rolling resistance in a hub comes from seals protecting the hub from the elements. We've optimized all the seals in Hydra2 to minimize friction. |

El resultado es un buje que puede soportar el uso extremo de los ciclistas más exigentes. Así es como lo lograron:
 Our new axle design is 65% thicker with an improved stress washer design. |  Larger, 5.5mm pawl pockets that evenly distribute force 26% better, preventing deformation of the pockets over years of use. |  We used an updated and more fatigue resistant steel for the drive ring and increased the pawl tooth count to 3, guaranteeing Hydra2 can easily handle the torque of the most powerful ebike motors. |

 Full-contact radial lip seals paired with proximity dust shields keep grit and grime out, and lubrication in. Durable 6903 bearings are used throughout for smooth, long-lasting performance. |

In the effort to make the Hydra2 hub bomb-proof, bullet-proof, and Brandon-proof, we didn’t compromise on meaningful performance gains, and the next generation has both quicker 0.41° engagement and 60% less coasting drag than its predecessor.

Combine I9’s trademark direct thread hubshell and machined aluminum spokes, and you’ve got a hub system with brains, brawn, and beauty — a piece of rideable art built by some of
the most innovative engineering minds in the cycling industry.
For the next generation of riders, bikes, and trails that demand the very best,
Hydra2 is the pinnacle of hub performance.
