Stans NoTubes STANS RIM TAPE 10YD X 27MM

WHAT YOU NEED TO KNOW:
Stans Yellow Tape is designed to work with tubeless-ready rims and wheels. If you'll be inflating your tyres to 45psi or less, one layer of yellow tape in the bed of your rim is all you need for most rims. For road tubeless and similar tyres that require more than 45psi of pressure, a double wrap of tape is required.

WHAT IF I HAVE AN OLDER RIM?
The BST (Bead Socket Technology) profile developed by Stans 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. Stans 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 Stans 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, Stans 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.
