This is the tape that is included with most of Stan's bundled tubeless systems. It covers the spoke hole and bare essentials to provide gap seal to prevent fluid leakage when running a tubeless setup. The tape also works as just a plain ol' rim strip. The tape roll is 10 yards long which is ample for a 2 pair of wheels and 12mm in width. One side is semi-adhesive and has some stretch to it. The material is quite robust and should give you any issues during install and when in use.
