KOM Light i40
Our proprietary 4D spoke drilling prevents binding and lateral loading of the spokes, while the spoke bed itself has been updated to provide a more compatible interface between the spoke and rim. Integration of the Solid Strip on our TCS rims delivers the easiest to mount and most reliable tubeless system we’ve ever made. A recessed channel along the center of TCS rims allows installation of the Solid Strip, which prevents tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tire and rim. Disc-brake only. Tubeless Ready.
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 Light i40 rim requires 45mm TCS Tubeless Tape).
