The Zéfal tubeless kit contains everything you need for Tubeless in addition to Tubeless tyres: specific self-adhesive rim tapes, Z-Sealant puncture prevention sealant, conical valves and valve tool. Our twin-material Tubeless tapes were designed to guarantee remarkable pressure resistance and durability. The addition of elastomer adhesive makes it possible to stop the sealant from infiltrating the rim. Finally, their slight elasticity makes tapes fitting simpler without any creases or bubbles.
