Industry Nine Trail Carbon 24H 29in Wheelset $2,500.00
The rebirth of carbon.
Industry Nine manufacturers two Trail Carbon 29in Wheelsets, one with 32 spokes and one with 24 spokes. If you charge aggressive lines, or you're a bit of a bruiser, opt for the 32 hole. However, if you're light on your feet and pick quintessential XC lines, then I9's 2:1-laced 24H Trail Carbon will provide you with 29-inches of fast spinning, lightweight bliss.
This wheelset shares all of the advancements of the Trail line, including the redesigned Torch hubs. The big news, however, is that carbon is finally joining I9's aluminum disco. These aren't just any run-of-the-mill epoxy and fiber-reinforced rings. Instead, Industry 9 enlisted help from the composite wizards at Reynolds Cycling. This means that these 29mm-wide outer, and 21mm inner, tubeless rims have Reynolds' encompassing MR5 technology. It focuses on five key elements -- spoke face, nipple bed, tire channel, rim sidewall, and hook bead -- in order to optimize resin chemistry and carbon layup for the structural and loads of each component. Long story short, this technology mated to I9's deft spoke and hub interface is a force to be reckoned with.
Instead of steel spokes, I9'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. Also, 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.
Industry Nine, however, doesn't need to roll its threads. Instead, they're created during the machining process, but 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, making nipples as useful on I9 wheels as they are on male mammals. The spokes also use a standard 15-gauge wrench and conventional truing methods in order to service. The Torch hubs that these spokes thread into are a fresh redesign of the groundbreaking Industry 9 hubs.
Accordingly, Industry Nine's new Torch hubs feature two sets of three pawls phased three degrees from each other. This 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, it has 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.
The Industry Nine Trail Carbon 24H 29in wheelset is available with a 15mm front and 142x12mm rear thru-axle compatibility. With end caps that are available separately, however, they're able to be converted to fit 20, 135, and 100mm standards. This wheelset is also tubeless-ready and comes in the color Black.

Anyone rolling these hoops yet ? Comparison...
Anyone rolling these hoops yet ? Comparison to ENVE ? Looking at carbon on the next all mountain build .
Here's my take: I9 hubs are solid. I've been on DT for years but there's a very good chance my next hub purchase will be I9. I9 buys their carbon rims from Reynolds--super quality without the bigger-name price tag that goes with ENVEs. ENVE rims are amazing. They're also overbuilt. Whether that matters to you is up to you. They're solid, market-competitive light, and I've had a few friends even complain that the 29AMs are maybe a little *too* stiff. ENVE manufactures right here in Ogden, Utah. I personally think that is rad and now that the new M series wheels are hookless, ENVE is on my short list. Reynolds is also based here in Utah but I do not believe they manufacture here. Reynolds offers a 2 year no questions asked replacement policy for $250. I have a number of friends who ride and race hard and I'm close to a number of local shop staff. I have heard all positive reviews for the Reynolds products. ENVE doesn't officially offer that no questions kind of coverage but I've had friends crack ENVEs (DH racing) and ENVE has taken care of them. All that said, my personal opinion is that you will be happy whichever way you go. I've been on my first set of carbon wheels for several months now on my Yeti SB-95c, I'm a big guy, I ride hard on the downs, and I've been extremely happy with the carbon. I ran FLOW EXs all last year and was completely satisfied with those. When I took my bike out the first time on carbon, it was like a brand new bike. Carbon wheels are the best upgrade you can give yourself, so make your bike happy and get some!
