What Our Gearhead® Experts Are Saying:
"I9’s Hydra hub is next level—I feel every bit of power translated to the trail, and the rims hit that sweet spot of light and strong. These wheels seriously sharpen up any trail bike."
Built to respond faster, ride harder, and track straighter, the Industry Nine Hydra Trail 270 29in Boost Wheelset brings unmatched responsiveness to the trail category. At its core is the legendary Hydra hub, boasting a nearly-instant 0.52° of engagement—giving riders precise control during technical climbs, quick accelerations, and tight switchbacks.
The Trail 270 rims are crafted from premium aluminum and feature a 27mm internal width to perfectly support today’s trail tire profiles. They strike an ideal balance between compliance and stiffness, providing stability in rough terrain without sacrificing agility. I9’s proprietary straight-pull aluminum spokes enhance lateral stiffness and deliver a ride feel that’s both responsive and forgiving over longer descents.
Whether you're racing enduro, riding steep alpine singletrack, or hitting your favorite home trails, this U.S.-built wheelset gives your bike the upgrade it deserves—responsive, reliable, and engineered to ride hard for seasons to come.

After getting a Yeti SB100 with GX and riding a bit with it I thought the DTs 1900 (25mm inner) and the DHF/Aggressor combo was a bit too much for someone like me, who rides mostly singletrack and trails here in Minnesota (Elm Creek, Cuyuna, etc). The bike is excellent (coming from a 26er 2005 Rocky Mountain Slayer 50 with DHF/Aggressor) but it felt like it could use a setup that would be bit lighter for faster climbing and longer, more XC-style rides. While everybody may want carbon, including me, I just wanted a solid and strong rim that was light. For around 1550g for the set it competes with carbon hoops and while they may not have the same riding feel (I haven't ridden carbon MTB wheels, so ignorance may be bliss in my case) they compare with most of them in terms of weight. I also wanted to experience the instant engagement that everybody has been raving about. While I was leaning towards Onyx (Minnesota!) a friend in the industry told me I would end up loving Hydra's buzz and performance, and they are lighter than the Onyx, which is what I was looking for. He wasn't wrong. The sound is very cool and the instant engagement is amazing. I don't think I would ever not want future hubs to not have similar or the same performance. I am hooked. Being 162lbs heavy and around 172-175 with gear, I thought the 24 holes would be perfect, especially since I like to ride fast but don't do huge airs, drops, or ride gnarly and rocky terrains. I paired them with Rekon 2.4 and Rekon Race 2.35 and the difference is very noticeable. Not only the instant engagement allows for faster acceleration and an overall better and smoother ride up or down, the way I can handle the wheels especially while descending is amazing, it just feels easier. I feel like the rider input is translated a lot quicker and without as much effort. The weight savings make it such a fast and nimble wheel and the bike feels just like that: faster and more nimble, with much better acceleration. The laser engraved graphics and the quality of the spokes are insane. The attention to detail is there in spades. The quality is superb and I don't hesitate a second to recommend i9 to other friends and fellow riders. I honestly can only say great things about this wheelset. For a second I thought I should have spent more money for a higher end component SB100 but I am glad I went this route and invested on this wheel upgrade for the most modest SB100 model. After selling the stock wheel-tire combo the SB100 came with and being able to get these on a 20% one item discount promo deal, I ended up setting myself back around $750 for the black hub and black spokes version, but the difference in performance is definitely worth the investment, so I couldn't be happier. Highly recommend if you want a strong, fast and versatile trail wheelset for singletrack, trail, and long rides. Competitve Cyclist's service and shipment was extraordinary, as per usual. Thank you for this amazing set!
