Stan's NoTubes Yellow Rim Tape has become the standard for achieving a proper seal when converting "normal" rims to tubeless. And by normal, we mean non-UST rims with spoke holes that pierce the outer wall of the rim. What's the big deal with Stan's Yellow Rim Tape you ask? Well, we don't know how it does what it does, but it makes the magic happen. When applied correctly, it provides a durable, long lasting seal.

Stan's Yellow Rim Tape is available in 12mm and 21mm widths and one roll is 10 yards -- just enough to do two sets of 29er wheels.
