Industry Nine spent two and a half years developing the Hydra, building on the legendary Torch series but nearly quadrupling the engagement of their flagship model, and once again revolutionising what a hub should do.
Industry Nine Hydra Hub Highlights:
– 690 points of engagement from a 6-pawl, 6-phase, 115-tooth drive ring with .52 deg between engagement points
– Angled flanges for lower spoke stress and large diameter disc flange improves wheel stiffness and brake torque transfer
– Weight: 286g (6-bolt, 12x148mm, rear)
– Increased durability and bearing life
– Lower Drag than the Torch Series
– 11 Anodised colour options
– All components other than the bearings are machined in Asheville, North Carolina
Classic J-Bend Hubs
Industry Nine Classic hubs are the heart of your wheelset, everything revolves around them, literally. Every Classic mountain hub is made start to finish in our Asheville, NC machine shop. From turning and milling bar stock 7075-T6 aluminum for shells, axles and endcaps, wire EDM cutting A2 tool steel for pawls and driverings, to our own in-house anodization lab, every step of design, engineering, manufacturing and assembly is done on premises to our exacting standards.
All New Drive-Ring and Pawl System
While the shell and hub themselves actually look quite similar to what you are used to seeing on the Industry Nine Torch Hubs, the insides of the hub are completely revamped in the Hydra. Gone is the 60 tooth drive-ring that has been a mainstay of Industry Nine hubs for the past number of years and, in its place, it an all new 115 tooth model.
The Torch hubs featured a 2-phase pawl system. At any given time, half of the 6 pawls in the Torch hub were engaged. Rotate the freehub 3 degrees and the other 3 pawls would engage.
With the Hydra, I9 has moved to an innovative 6 phase engagement system. This means that at any given time one of the pawls in engaged on the 115 tooth drive-ring, and the system uses the flex in the system to achieve 2nd, 3rd, and 4th pawl contact to distribute the load.

The trailblazing A2 is Troy Lee Designs’ MTB trail helmet that checks all the boxes. Its stylish shell not only incorporates huge intake and exhaust ventilation ports, but it also comes with the very best in impact protection. From breakaway visor screws and the innovative MIPS® system and an industry-first dual-density EPP + EPS liner that protects against both high and low-speed impacts; this is a helmet that doesn’t take your safety lightly. Add in an adjustable strap and X-Static® Pure Silver comfort liner and the comfort is every bit on par with the protection.
It might look normal from the outside, but the engineering inside this incredible chain design makes possible a gear range previously found only in 2-chainring drivetrains. And it's also the biggest contributor to the Eagle drivetrain's ultra-smooth, precise, durable and quiet performance. The Eagle chain's links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs.
