Product description
Simply put, KOM Tough rims were built for bashing. We designed them to overcome everything in their unforgiving path. KOM Tough rims are extruded from top-tier 6069 aluminum alloy for unbeatable durability at a reasonable weight, while Dual I-Beam supports further increase strength and lateral stiffness for the world’s most aggressive riders. WTB's unique Solid Strip integration also ensures they'll be the easiest to mount and most reliable tubeless rims you'll ever own. KOM Tough has been proven on the toughest tracks of the Enduro World Series, depended on for daily trail rides, and trusted while bikepacking in remote regions of the world.

Frequently Asked Questions
Wider rims will cause a tire to also have a wider width, with more air volume within the tire and a flatter tire tread profile than designed for. As a general rule of thumb, a 2mm increase or decrease of inner rim width will result in a tire section width increase or decrease of 1mm. For example, our Nano 40 tire has a tire section width of 40mm on a 21mm inner rim width, however it will have a tire section width of 41mm on a 23mm inner rim width.
All of our alloy rims work great with a 34mm valve stem. If you are using a deeper dish rim, like our CZR i23 rim, then we recommend the 46mm long valve stem. CZR i30 rims accept either length of valve.
WTB recommends using tape that is 5mm wider than the inner rim width. All WTB rims have the inner rim width listed in the name (i.e. KOM Tough i30 rim requires 35mm TCS Tubeless Tape).
