Before gluing Caffélatex Tubeless Tape inside the rim, carefully clean the rim-bed, removing any trace of grease or lubricant (use alcohol or other de-greaser, then - VERY IMPORTANT – clean carefully with a clean, dry cloth. Adhesion of the tape on dried-up alcohol is not good). Use a sharp spike or a screwdriver to make a round hole in Caffélatex Tubeless Tape at the valve hole. AVOID using a cutter knife and doing an “X” cut, that would prevent proper air-tightness at the valve base.
