Effetto Mariposas Cafflatex Tubeless Strip is a very light, puncture-proof and transparent tubeless rim strip that makes tubeless conversions quick and easy. Strip allows tubeless conversion of most standard bicycle wheels, using Tubeless or Tubeless-Ready tyres and Cafflatex or Vgtalex sealant. WARNING: using sealants containing aggressive chemicals or ammonia, or cleaning the rim with aggressive chemical products can damage Cafflatex Tubeless Strip and may represent dangers to the user. Effetto Mariposa recommends using only Cafflatex or Vgtalex sealants, or Espresso/Espresso Doppio inflate & repair cartridges with Cafflatex Tubeless Strip.
