Unmatched engagement and trail-tuned control from the Hydra Trail 270 29in Boost Wheelset
What Our Gearhead® Experts Are Saying:
"These wheels completely changed how my trail bike rides. The instant Hydra engagement is unreal on tech climbs, and they stay stiff and true through everything from desert chunk to loamy singletrack."
When we’re pushing hard through corners or ratcheting up technical climbs, we need wheels that respond immediately and hold their line with confidence. That’s exactly what the Industry Nine Hydra Trail 270 29in Boost Wheelset delivers—lightweight agility and class-leading hub engagement, tailored for modern trail riding.
At the heart of the system is I9’s Hydra hub, offering a blazing-fast 0.52° of engagement—perfect for punchy climbs and precise technical moves. The 27mm internal rim width pairs well with 2.3–2.5in tires, giving us ideal support and shape without compromising weight. Laced with I9’s signature aluminum spokes, these wheels blend lateral stiffness with vibration damping to reduce fatigue on long descents. From backcountry loops to after-work hot laps, this wheelset is ready to elevate every ride.

Just what I wanted -
- Familiarity:
- I've put it through the wringer
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!
