The Muc-Off Tubeless Rim tape is made from their own proprietary performance material with a pressure-sensitive adhesive to provide just the right amount stretch whilst maintaining durability and strength needed to create a lasting airtight seal. Semi-transparent material makes locating the valve hole easy. Supplied with 4x Seal Patches. The Tubeless Rim Tape that you go for should be matched up with the size of your wheel's internal rim width. You should be able to find this measurement on the inside of your rim, or alternatively check your bike's manufacturer's guide online. Failing that, it's time to dig out a trusty ruler and measure it yourself! If your rim width doesn't match up exactly with our sizes below, just go for the next size up.
