    Hydra Enduro S 29in Super Boost 157 Wheelset

    Tackle big backcountry rides and challenging enduro descents with the Industry Nine Hydra Enduro S 29in Super Boost 157 Wheelset. As a more budget-friendly alternative to the Enduro 305 wheelset, these wheels use the same high-engagement Hydra hub system, but use straight-pull spokes made of steel rather than aluminum, considerably lowering the barrier to entry. The speedy Hydra hubs offer a staggering 690 points of contact that propel you forward with 0.52-degree engagement, resulting in one of the most responsive hubs we've seen to date. The hubs are laced up to I9's beefy Enduro S rim, providing a solid platform that stays durable season after season, and they come in 157mm Super Boost rear spacing to accommodate bikes that use this increasingly common standard.

    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, which allows the aforementioned 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.
