The BST (Bead Socket Technology) profile developed by Stan's NoTubes was a departure from traditional bicycle rim design, and its core concept is the basis for the vast majority of "tubeless-ready" rims and wheels on the market today. Stan's Yellow Rim Tape is not, by itself, a tubeless conversion for older, traditional, non-"tubeless-ready" rims. These older rims require the use of a Stan’s NoTubes Rim Strip (now discontinued) to re-shape the rim bed to achieve a safe, secure tubeless setup. While we would recommend considering a new tubeless-ready wheelset in place of a rim strip conversion, Stan's Rim Strips and kits may still be available at your local bike shop and can be used to convert vintage bikes with older, non-tubeless-ready rims. Using only Yellow Rim Tape and Stan’s NoTubes sealant on a non-tubeless-ready rim can result in not only difficult inflation during set-up, but catastrophic "burping" issues while riding. While Stan's Rim Strips have been discontinued, we continue to provide information and resources to assist in converting non-tubeless-ready wheels. Visit our Support Center videos for more details.
