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 whee...
