Tubeless tyres need to make an airtight bead-to-rim seal in order to function. Tubeless-ready wheels have holes drilled into the rim bed to allow easy access for the spoke nipples. Tube rim tape is essential to make a tubeless-ready wheel airtight, as it seals up the holes in the rim bed. My Ride stocks Muc-Off tubeless tape in a variety of widths, designed to suit all of the most common road, CX, gravel and mountain bike wheel sizes.
