Tipping the scales in the sub 1400 gram category, the Industry Nine Ultralite 27. 5in Tubeless Wheelset gives you a competitive advantage in cross country races. 27. 5 inch wheels roll over obstacles easier than 26 inch wheels without the extra rotational mass of their 29 inch counterparts, ensuring fast acceleration and smooth tracking over undulating cross country terrain. One its biggest advantages lies within machined 7075 aluminum spokes, with a 25% greater cross section over comparable double butted steel spokes. This improves tensile strength, while using 24 spokes at the front and rear wheels for significant weight savings. To compensate for the lower spoke count, the wheel's 2:1 lacing ratio places 16 spokes along the side bearing the larger load to improve balance and stability. Please note the Ultralite Wheelset works best with riders under the 180 pound weight limit, which makes sense considering its cross country racing pedigree. The Ultralite wheelset's Torch hubs feature separately available end caps, ensuring compatibility with front and rear thru axles, as well as their quick release counterparts. Straight from the box, they're ready for use with a 15 millimeter front and 12x142 millimeter rear thru axle, with the XD driver equipped option fully compatible with SRAM's 10 42 tooth cassette. However, the big story with the wheelset's Torch hubs is their near instantaneous three degrees of engagement and 120 points of contact, which makes for powerful acceleration during racing scenarios. Moreover, the hubs' Teflon shields and endcap O rings seal out trail debris and grit from degrading performance. Looking to the tubeless ready aluminum rim, its double wall extrusion adds stiffness without excess weight. In fact, they only weigh 352 grams each, making them just as light as many carbon rims on the market. They're sufficiently wide to run a true 2. 4 inch tire, thanks to their 25. 2 millimeter outer width. And because they're tubeless ready with ...
