Effetto Caffélatex is a truly innovative tyre sealant, successfully used on and off (MTB, cyclocross) road, for tubeless, tubular and inner-tube applications.
Foaming action activated by wheel movement:
The first advantage of Caffélatex over classic latex-based sealants comes from a foaming agent (Actifoam™), activated by wheel movement. Centrifugal force drives standard latex-based sealants against the outer circumference of the tyre. Caffélatex foaming action causes it to fill the tyre’s entire internal cavity , making it much more effective against sidewall punctures.
Its fast sealing action makes Caffélatex ideal for MTB and road tubeless, tubular and standard tyres. Caffélatex repairs punctures up to 5 mm (mtb) and 3 mm (road).
Stable over time:
Thanks to its formula, Caffélatex is a very stable and durable sealant, but we know this is highly dependable on kind of application and external conditions.
Using the recommended quantities for tyre size, the expected sealant lifespan is:
Tubular (or Caffélatex inserted into latex/butyl inner tube):
UST Tubeless tyre: 4-6 months
Tubeless-ready tyre: 2-4 months
Tube-type tyre: 2-3 months
Nevertheless, in the impossibility of knowing our customers’ specific application (kind of wheel/tyre set-up, tyre sidewall thickness and porosities, external temperature and humidity, bicycle storage conditions…), we recommend checking Caffélatex every 2 months, to make sure it’s liquid and therefore retains its ‘puncture preventive’ action.
When dry, Caffélatex-sealed wheels are still air-tight, but Caffélatex won’t actively repair punctures.
being completely ammonia-free, its 100% tyre and rim friendly. It’s also a favourite sealant for cyclocross/tubular applications, creating no harm to the sensitive latex inner tubes.
Usage and storage temperatures:
From very cold to very hot, exceeding by far those of first-generation latex sealants (usage: -20/+50°C ~ storage: -15/ +30°C).
30 to 50 ml per wheel for road/cyclocross applications; 50 ml for mtb tyres up to 26×2.10/29×2.00; 60 to 100 ml for mtb tyres over 26×2.10/29×2.00.
"When we removed our 6mm screwdriver, the Caffélatex sealed the hole almost instantly. Even after wiggling the tool around it didn’t take long to plug the hole. If you buy the one-litre bottle, it’s great value too."
'What Mountain Bike'
Even after wiggling the screwdriver around, it plugged the hole on the second revolution of the wheel, making it a slightly faster hole-plugger than Stan’s.
It’s the cheapest on test, though, and if you buy the 1-litre bottle, it’s surprisingly good value.
