Hold Fast Tubeless Tape

Hold Fast Tubeless Tape is tubeless rim tape that comes in 10-yard rolls and five widths: 21, 25, 28, 32 and 36mm. Extra adhesive helps it grip the range of rim surfaces you will find, and a slightly thinner top layer adds flex and elongation so it follows more rim profiles. The tape is cream, not yellow. It only looks yellow in photographs.

To pick a width, measure your rim's internal width, then check whether the rim is hooked or hookless. The same internal width can take a different tape depending on which it is. The 25mm tape, for example, suits hookless rims of 23-26mm internal and hooked rims of 20-24mm internal. The range runs from 21mm tape for the narrowest rims to 36mm for hookless rims of 35-38mm internal.
