Effetto Caffelatex Tubeless Rim TapeDesigned to replace standard rim-tape, Caffélatex Tubeless Tape perfectly adapts to the internal rim profile and makes standard rims airtight by sealing the spoke holes. It allows tubeless conversions of most standard mountain bike wheels, using Tubeless or Tubeless-Ready tyres and Caffélatex sealant. Three different widths are available: S: for rims with external width between 20 and 24mm; M: for rims with external width between 25 and 29mm; L: for rims with external width between 30 and 34mm. Features: Made of polyester: The best material for technical tapes, with very high strength properties. Stable: It easily conforms to rim shapes and has low memory (it doesn’t ‘spring back’ once put down in the rim channel). Adhesive strength: The adhesive can stick to silicone-treated paper and is much more tolerant to less-than-perfect rim cleaning before tape application. Smaller core: 1 inch instead of 3 inch-diameter cores of most tapes, to save space and to make it easier to tension it while taping the rim (inserting the thumb inside the core, it happens very naturally). Sealed: to preserve the tape properties and to underline its “technical product” status, each tape is now contained in a re-sealable bag.
