If you're one for following trends in the industry, chances are you've already gotten some of the low-down on Industry Nine's new Hydra hubs, but chances are you haven't yet had the opportunity to saddle yourself up with a pair. Fortunately for you, the wait is over, and we're stoked to spread the hype with Industry Nine's new Hydra Trail 270 29in Boost Wheelset. These steamrolling hoops combine the classic Trail rim we know and love with I9's new Hydra freehub that offers some intensely quick actuation. We could say they telepathically communicate with you to transfer power to the trail before you even know that you put it out, but that would be taking away credit from the meticulous engineers in Asheville, NC, who spent two-and-a-half years tinkering with this hub to dial in near-instantaneous 0. 52-degree engagement, for the snappiest wheelset we've ever laid our hands on. The Hydra hubs build on Industry Nine's previous drive system, which is pretty easy to spot if you take a peek at the internals. You'll spot a similar pawl layout that we've seen before in the Torch, and the same pristine CNC machining coming straight from Asheville, North Carolina. Like the old Torch hub, the Hydra features a 6 pawl design, but the drive ring amps things up to a 115-tooth drive ring, as opposed to the 60-tooth used in the Torch, creating a whopping 690 points of engagement, blowing the 120 points of engagement of the Torch out of the water. These 690 points of contact translate directly to the snappiest hubs we've ever seen, with only 0. 52-degrees of engagement, propelling you forward just about the instant you put any power down. Furthermore, the engineers opted to keep things simple for those of us who tinker on our bikes at home, making the hub fully serviceable without any proprietary tools. For your all-mountain endeavors, I9 laces up the Hydra hub with its Trail 270 rims to make this slick set of hoops. I9's Trail rims remain the same as we saw in combination with ...
