About I9 Hubs
Built to Ride
Industry Nine hubs are machined, anodized and assembled entirely in their Asheville, NC manufacturing facility. You can fully service the hubs with standard bearing tools, no proprietary tools required.
With 690 points of engagement, increased durability and bearing life, decreased rolling resistance and weight, the Hydra is I9’s premium hub. The Hydra features a 115 tooth drive-ring and a six phase engagement system, that achieves 2nd, 3rd and 4th pawl contact to distribute the load. Learn more about the Hydra by visiting our blog.
The Torch’s three-pawl dual-phase system features a 60 tooth drive ring. With low rolling resistance and little sound, the Torch is a great hub for your dropbar bike.
The 1/1 offers 90 points of engagement through its 45 tooth dual phased drive mechanism. Their simple design offers the durable performance expected of Industry Nine hubs at a low price. The 1/1 only comes in black.

Grease Vs Oil
Dumonde produces a line of resilient and effective oils and greases, as a result, Industry Nine suggests Dumonde as a lubricant for their hubs. The Hydra hub has the option of using either Dumonde’s thicker grease or their lower viscosity oil. Each one affects how the hub behaves and the level of maintenance required. Check out our blog post to learn more.
Servicing Your I9 Hub
We suggest bringing your wheels to a bike shop or sending them to us for maintenance, but if you like to do things yourself you’ll want to watch this freehub servicing video.
