Hydra Enduro 305 29in Boost Wheelset

We won't deny that we've become big fans of Industry Nine wheels over the years, especially ones that feature their precision-machined, high-engagement Torch hubs. So when we heard that the North Carolina based company had a new hub design with even quicker engagement than Torch, we were eager to get our hands on a set of these new hubs they call Hydra. Offering a groundbreaking 0.52-degrees between engagement points, Hydra are the some of the most responsive hubs we've ever laid hands on. We're happy to offer them here as the complete Hydra Enduro 305 29in Boost Wheelset, laced up with Indusry Nine's signature straight-pull spokes and burly Enduro 305 alloy rims, creating a bruiser of a wheelset that makes quick work of steep descents and challenging terrain.

The Hydra hubs build on Industry Nine's previous drive system, featuring a 6-pawl design like the Torch hubs, but the drive ring is boosted up to 115 teeth as opposed to the 60-tooth design found on Torch. The pawls are also independently phased, engaging in procession as the axle rotates, resulting an an unheard of 690 points of engagement with just 0.52-degrees between each engagement point. While this provides near-telepathic response when you apply force to the pedals, one of the primary benefits is increased durability. With the Hydra's independently phased system, you have one leading pawl that starts to take the load from pedaling, but because the pawls are phased close together and the tooth count is so high, as soon as you apply torque to the system a second, third, and sometimes even a fourth pawl start taking some of the load to disperse the force more evenly. Basically, Hydra uses the inherent flex in the drive system to ensure that a single pawl will never take the full load, minimizing wear and tear on the freehub body and drive-side bearings.

In order to cater to riders wanting a strong wheelset for aggressive trail riding and enduro racing, I9 laces up the Hydra hub with their burly Enduro 305 rims. Featuring stiff and reliable aluminum construction, a wide 30.5mm internal width, and a dent-resistant profile, these rims won't shy away from taking the straight line through chunky rock gardens and gnarly exposed roots. And thanks to 32 straight-pull spokes that thread directly into the hub shell to create a solid, flex-free junction, you'll enjoy precise tracking over rough terrain and long-term reliability on the trail.
