Industry Nine Trail 29in Wheelset $1,195.00
Burly yet light.
Getting up and over craggy, steep sections of trail requires short bursts of maximum torque at opportune moments. In other words, ratcheting. This places the highest load on two key, but little thought about components -- the pawls and the engagement ring. To counter this, Industry Nine uses a hardened A2 engagement ring with 60-teeth and six pawls in its Trail 29in Wheelset.
This results in a design that's been tested to 700ft/lbs of torque -- roughly what a built diesel truck puts out -- and serious reassurance in those moments when you're maxed out. During steep, technical trail sections, quick engagement is also essential to cleaning them. Accordingly, Industry Nine's new Torch hubs incorporates a proprietary mechanism that features two sets of three pawls phased three degrees from each other.
The Trail wheelset retains the same proprietary spoke and hub interface, but has received numerous advancements to the hub itself. The new Torch hubs are now compatible with all axle standards via separately available end caps. The big news, however, is within the hub. The Torch preserves the 120 points of contact and lightning-quick three degrees engagement that distinguished Industry Nine, only now, the pawls have two teeth instead of three. Along with that, a changed cantilever angle and shallower tooth profile on the hardened drive ring reduce drag for a less-restricted freehub. Remarkably, this occurs with the same holding power. And, that's not all that I9 did to improve the Torch.
Its engineers removed the large bearing between the freehub body and shell, opting for smaller bearings directly between the body and shell. The reduced bearing size means less seal surface area that, along with a new silicone lip design, significantly reduces mechanical drag. The freehub is also now easier to remove for cleaning/lubing, and like before, the springs and pawls are captured. So, you won't be scrambling on a floor looking for small parts.
Instead of steel spokes, I-9's wheels use 7075 aluminum. The spokes are straight pull, and they have roughly a 25% greater cross section then comparable 14/15 double butted steel spokes. In other words, these spokes have a stronger tensile strength. Threading on these spokes is also exclusive to Industry Nine. On traditional spokes, threads are rolled, not cut. This adds to strength, but creates a stress riser where the thread channel is narrower than the diameter of spoke itself. However, Industry Nine doesn't need to roll its threads. Instead, they're created during the machining process, only they're cut so that the thread channel is the same as the spokes diameter. The threads themselves are actually larger than the spoke for a strong interface with the hub.
That brings to light another defining feature of these wheels -- there are no nipples. The spokes thread directly into hub in order to eliminate a redundant part. They also use a standard 15-gauge spoke wrench and conventional truing methods in order to maintain serviceability for long-term use.
With a 28mm outer width (23.4mm inner), the Industry Nine's Trail rim is one of the widest 29er rim on the market, making it a perfect fit for the enduro purpose of this wheelset. They feature a double-wide design for strength without a heavy weight penalty, and they also provide an excellent level of stiffness for precise tracking over the rough stuff.
The Industry Nine Trail 29in wheels are available with a 15mm front and 142 x 12mm rear thru-axle compatibility. They're tubeless-ready and come in either the color Black or Red. Please note that they ship with the Presta valve stems and rim tape already installed.

Great wheel-set . Running a 2.35 on the front and a 2.2 on that rear. No complains. These wheel-sets are light and fast. Love the I9's hub sound

I had been riding on some Easton EA90 XC for the last two years and even if I like those wheels, I love my new i9 Trail wheelset. These wheels feel very strong and the engagement on the hub is just phenomenal. I got the wheels only a week ago but have already put about 200 miles on them, 80% flowy trails and 20% hard riding trails. I used to have a hard time going up some technical climbs, but not anymore with this wheels. I felt the difference and confidence right away on those same exact technical climbs.

these wheels are incredible. stiff, light, wide, super easy to set up tubeless, and major eye candy. All the dudes i ride with really dig them. too bad they are all dudes though....
