Hydra Enduro 305 V3 27.5in Boost Wheelset

When big climbs lead to long, challenging descents, you'll be glad your bike is kitted out with the Industry Nine Enduro 305's. Strength and reliability are first and foremost with these top-level aluminum wheels, but I9 keeps the weight reasonable so you aren't held back on climbs and sprints. The V3 rims feature a lower profile than previous generations, which leads to a more compliant ride without sacrificing strength. Oversize straight-pull aluminum spokes are laced to I9's flagship Hydra hub with a staggering 690 engagement points, meaning there's no lag when it's time to put the power down.

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 in 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.
