Ultralite 235 CX Disc Wheelset

Lacing Industry Nine's Ultralite 235 mountain rim to the chassis of their i25TL Disc Wheel, the Ultralite 235 CX Disc Wheelset achieves a feathery weight and robust support for running wider tires in the neighborhood of 30 to 55 millimeters. As its name implies, it's a solid alloy wheelset for cyclocross racers and adventurous gravel riders alike. It satisfies those seeking a lightweight wheel that doesn't sacrifice strength or support when you're pummeling your cross bike on race day or exploring light-duty singletrack and back roads on your gravel rig.

To achieve an optimal ride quality, reliable strength, and even spoke tension, Industry Nine uses 16 spokes along the rear wheel's drive side, complemented with 8 on the opposing side. This spoke orientation not only serves to balance spoke tension, but it also reduces the stress exerted on the rim, as well as lessening fatigue exhibited with a traditional 24-hole spoke wheel. By using this lower spoke count in a 2/1 lacing pattern, Industry Nine achieves a feathery-light wheelset that's reliably strong for your cross and gravel grinding needs.

As you'd expect from Industry Nine, this wheelset benefits from the responsive 6-degree engagement of their Torch Road Hubs. The Torch Road Hub is slightly reconfigured from their usual Torch Mountain Bike Hub, with a reduced 3-pawl count (down from the usual 6) lessening drag and weight. Revised bearings and a reconfigured freehub seal work to lessen drag while you're coasting.

  • Ultra-light and reliably strong for cross and gravel
  • 23.5mm internal width supports wider tires of 30 to 55mm
  • Alloy construction for optimal strength-to-weight
  • Tubeless-ready for achieving bump compliance and grip
  • 24 spoke count, with 2/1 lacing on rear for strength
  • Torch Road hub with responsive 6-degree engagement

Great wheelset

I've put it through the wringer

I've have almost 4k miles on these wheels and they've been flawless. I haven't been kind to them either. They handle road, gravel and light mountain stuff here in the northeast which always means at least some rocks and roots. Caught a large stick in the rear derailleur that bent the hanger, but the spokes held on. Can't say enough good stuff about them. Really. And they're just as light as a carbon wheelset at 1/2 the cost.

Maybe a little too light...

I've put it through the wringer

I've ridden these for a few seasons on gravel, and they didn't hold up very well. Initially the only problem was just lots of issues getting them to seal up for tubeless tires, which isn't so big a deal, but then it progressed to parts rolling around inside the rim, and then creaks and pops, and untruing. I'm rebuilding them now, and I'm seeing several things I dislike about the stock build. The parts rolling around inside the rim are fragments of aluminum nipple washers that disintegrated, and caused the wheel to untrue. It couldn't be corrected without dismantling the entire wheel because the spokes were speced at too long a length imo, and there was only about 1/2 a turn left on the threads, so no slack could be taken out. Furthermore, some kind of spoke gunk was used that made it very difficult to turn the nipples, which are aluminum, so good luck not destroying them. Finally, the rim tape used sucks. It sealed poorly, and somehow even managed to adhere itself to the tires. A lot of these issues are just results of wear and tear when using the lightest weight materials, and these wheels were billed as light, not bombproof- but I think some of the design is questionable. Specifically the aluminum washers. And the rest was just build quality... If you like very loud hubs, the torches are for you!


I have a set of these wheels on order. Do you have QR adaptors available, or do I need to source them from i9 directly? ... or, are they included?
