The Effetto Mariposa Caffélatex is a truly innovative tyre sealant, successfully used for road and off-road cycling, in tubeless, tubular and inner-tube applications.

  • Doesn’t contain ammonia or other aggressive chemicals.
  • Best durability and puncture repairing ability mix.
  • Turns into foam when agitated, spreads easily and without unbalancing the wheel.
  • Used successfully in cyclocross, road and mountain bike at all levels, from leisure riding to professional racing.
  • One formula only: professional racers use what anyone can buy.

Foaming action activated by wheel movement - the first advantage of Caffélatex over classic latex-based sealants comes from a foaming behaviour, activated by wheel movement. Centrifugal force drives standard latex-based sealants against the outer circumference of the tyre. Caffélatex turns instead into foam, filling the tyre’s entire internal cavity, making our sealant much more effective against sidewall punctures. Caffélatex go back to liquid state after around 15 minutes of stillness.
Puncture-repairing action - its fast sealing action makes it ideal for mtb and road tubeless, tubular and standard tyres. Caffélatex repairs punctures up to 5 mm (mtb tubeless) and 3 mm (road tubeless).
Stable over time - thanks to its formula, Caffélatex is a very stable and durable sealant, although its lifespan is also dependant on kind of application and external conditions.
Not corrosive - being completely ammonia-free, it’s 100% tyre and rim friendly and also the favourite sealant for cyclocross/tubular applications, creating no harm to the sensitive latex innertubes.
Usage and storage temperatures - from very cold to very hot, exceeding by far those of first-generation latex sealants. Usage: -20°C to 50°C. Storage: -15°C to +30°C.

It's Great, A1

After some below average results with another leading brand I gave this a go after reading some great reviews. In short I wouldn't use anything else now. It's great and the foaming action seems to be a winner. I run 29er's ~ 2.5in Maxxis tyres on enduro mtb.
