Fulfilling your cross-country racing needs, the Industry Nine Ultralite 235 29in Boost Wheelset delivers lightweight efficiency, stiffness, and enhanced traction that leaves the competition eating dust. Tipping the scales at a feathery 1455 grams, the Ultralite 235 drops serious weight off your XC whip for instant acceleration when you're cranking up long climbs and bursting out of corners. However, that's not to say it's lacking in strength when you're plunging into rocky downhills or technical stretches. Robust aluminum construction, tapered spokes, and a revised design places extra material where it's needed most to ensure the durability needed to ride hard.
Overhauled for a wider footprint, the wheelset's 23.5mm internal width accommodates a 2.3-inch tire for greater traction and better bump compliance on rough trails and technical courses. Boost axle standards significantly increase wheel stiffness, which is something that's plagued 29ers since inception. By converting to Boost standards on your 29er, your front wheel's stiffness becomes comparable to a 26-inch wheel, with the rear becoming just as stiff as a 27.5-inch wheel. Ultimately, this equates to precise tracking and extra confidence for holding tricky downhill lines.
The Ultralite 235 Wheelset uses I9's highly acclaimed Torch hubs, which feature near-instantaneous three-degree engagement for powering up and over trail obstacles with ease. Teflon shields and O-rings snap solidly onto the end caps of the hubs, preventing trail grit from slowly compromising the wheel's smooth characteristics. The Ultralite 235 comes tubeless-ready with factory-installed rim tape and Presta valves. Choose the HG driver if you're riding a Shimano/SRAM 9/10-speed drivetrain or pick up the XD driver version if you're running the latest 11/12-speed drivetrain from SRAM.
