Why We Like The Hydra Enduro S 29in Boost Wheelset
Pairing the finely-crafted Hydra hubs with the proven rim profile of the Enduro 305, the Industry Nine Hydra Enduro S 29in Boost Wheelset offers elevated performance on challenging all-mountain terrain, but comes in at a more approachable price thanks to the use of 28 straight-pull steel spokes instead of the aluminum found on the 305's. As for the hubs, the I9 Hydra are the snappy new hub option on the block, offering 690 points of engagement that propel you forward with an impressive 0.52-degree engagement, resulting in one of the fastest hubs we've seen to date. They're laced up to I9's beefy Enduro S rim, providing a solid platform to tackle black diamond runs and all-day epics in the backcountry.
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.

This wheelset came with my bike and they're just flat out awesome. Hub sounds like a hype pitched hum, but the engagement is instant and I'm enjoying riding more than I ever have in my life. Buy it.

These hubs are really smooth on their own but pairing them with an Absolute Black Oval Chainring they are super smooth!! I think it's the quick engagement with Oval that makes them shine. The sound isn't bad, when going downhill fast I feel like I have an engine humming behind me. I have had people ask me why it sounds different. Even without the oval chainring you will be happy with them! I put on the colored value stems to finish off my build. Plus, the price is reasonable compared to the carbon versions. Enjoy!

The question is do you actually have these in stock? I ordered them from another supplier and they said back ordered until October!
