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

The artist’s view: the Caffélatex cow!
The artist’s view: the Caffélatex cow!


  • 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


How it works:

thanks to the addition of microscopic silicate particles, Caffélatex moves slowly through holes, allowing the sealing ingredient more time to heal the puncture. These particles are not macroscopic (e.g., glitter 150-300 microns) but are instead microscopic, less than 2 microns in diameter. Thus, Caffélatex flow characteristics change on a microscopic level without the headaches of valve-clogging glitter.
Puncture repair speed is especially noticeable with lightweight or thin-casing tires.

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).

Caffélatex family: sealants & tubeless products
Thanks to its squeezable pouch and perfectly calibrated hose, Caffélatex 60 ml allows direct injection through Presta valves. Easy to transport, it’s ideal for also for road applications (60 ml / 2 ounces is the correct quantity for two 23 mm tubulars)

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.
Using the recommended quantities for tyre size, the expected sealant lifespan is:

  • Tubular (or inserted into latex/butyl inner tube): up to 1 year
  • UST  Tubeless tyre: 2-6 months
  • Tubeless-ready tyre: 1-4 months
  • Tube-type tyre: 1-3 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.

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.

Tubeless conversion: the whole truth!

Those who ride occasionally (less than once a week), do not cross lands infested with thorns or – simply – do not want to face the small problems and complications that tubeless involves, can continue using inner tubes and be happy like that. In off-road riding, however, the transition to tubeless and the use of […] READ ALL

Caffélatex, valves and inner tubes

Being a synthetic latex, Caffélatex is not as intrinsically “sticky” as natural latex sealants, showing a lower tendency to clog valves and valve mechanisms. Still, it’s important to learn how to use it properly to take full advantage of the puncture protection, reducing the drawbacks to the minimum. General tips for long lasting valves, when […] READ ALL

Caffélatex and the “hair dryer” effect

Beside the use of CO2(described here) or contamination of your sealant with other products(described here), the “hair dryer” effect is a common but little-known reason for the decrease in a sealant lifespan. When does it happens? If a tubeless tyre doesn’t immediately inflate after having inserted the sealant, some people using a compressor might be […] READ ALL


Tyre sealants are a must-have for the performance-oriented cyclists, to avoid the feared and annoying punctures. The big question is: how much sealant do I need? Parameters that influence the necessary quantity of sealant: Several parameters should be taken into account, for example the outside humidity, temperature and tyre inflation routine/regularity. However, the main factors […] READ ALL

A Caffélatex cocktail

The most common reasons for polymerization of latex sealants (synthetic or natural) can be divided into two groups: physical (related to temperature changes, evaporation, etc.); chemical. Physical: a sudden temperature drop, e.g. when using CO2 cartridges, as described here; a quick evaporation, e.g. when the sealant comes out from a puncture in the tyre. In this case the […] READ ALL

Caffélatex and tubulars

Why Caffélatex rather than other sealants? Caffélatex has some important features which make it a good choice as puncture preventative inside tubulars: non-corrosive: the complete absence of ammonia or any other aggressive chemical makes Caffélatex perfect even for very sensitive latex inner-tubes (quite common inside professional tubulars). Caffélatex is perfectly compatible also with tubulars with […] READ ALL

Caffélatex and CO2

While Caffélatex resists well to both low and high temperatures (between -20 and 50°C), sudden temperature changes are not good for its stability. A strong thermal shock could be a polymerization-starter for any latex-based sealant (natural or synthetic), so we suggest to limit the use of CO2 cartridges or, if necessary, to do it with extra […] READ ALL

  1. I live in a hot (30 degrees c) and humid environment. Will that affect the longevity of caffelatex either in my tubular tyres or the 60ml pouch?

    1. Hello Andy, generally speaking, hot weather tends to reduce the lifespan of sealants.
      As for Caffélatex inside the 60 ml pouch, there shouldn’t be problems, as the pouch is airtight and there cannot be any evaporation. As for the Caffélatex inside your tubulars, yes, it’s possible durability will be lower than in colder weather… but we’re still talking about several months.

    1. Shelf life of Caffélatex is very long. It certainly exceeds two years, which is considered the golden standard for sealants.
      After having been opened, a bottle of Caffélatex will last a maximum of two years, if properly closed and stored away from direct sunlight and/or heat sources.

  2. Should I clean the sealant (remove the remaining Caffelatex) every time I check the tire and see that I must fill it with another dose?

    1. If you see liquid Caffélatex when you check your tires and you want to top it up, you can simply add more liquid sealant: no need to remove what’s inside.
      If, on the other hand, the sealant is dry, just remove the (eventual) bigger solid chunks before adding some fresh Caffélatex.

  3. Hi,
    My tubeless tyres have been filled with continental revosealant, I would like to use your product, is there any problem if I mix the 2?

    1. It can be done with Caffélatex Remover.
      Apply Caffélatex Remover on the stain(s), allow it to work for some second, then rub on it with a clean cloth. Degree of success depends a lot on the kind of fabric and how much it has absorbed the sealant, as the Remover will efficiently soften what is on the surface but it will have an harder time with what’s inside the fabric.

  4. From the product description, it looks like I can add Caffélatex to latex inner tubes for non-tubeless road tires (tube-type tyres). Am I correct? If yes, what is the best care of the tube and sealant to prolong their life? Thanks!

  5. I want to use caffelatex in my brand new Continental Competition 22mm Tubular, how much pressure shall i use in the tire after i have filled in the Caffelatex? I ask because in the movie with the 60ml it says max. 3 bar !!

    1. Hi Kim, thanks for the opportunity to clarify this matter: the 3 bar max pressure we show in Caffélatex 60ml video only applies to mtb tyres mounted as tubeless (as there’s no need to exceed that when installing tubeless mtb tyres).
      For road tubulars or tubeless with Caffélatex inside, the maximum inflating pressure remains the one recommended by the tubular/tyre producer.

  6. It’s life span is: Tubeless-ready tyre: 2-4 months, how to check if sealant is too old? Is there a way to do it? Do i have to replace Caffe Latex every 3 months to be sure that it’s working?

    1. That’s a good question: if, upon checking, the sealant is still liquid, it surely is still effective.
      A quick way to test if Caffélatex works:
      – wet the tip of your thumb and index in the sealant
      – pinch firmly the two fingers together for 10 seconds
      – if, releasing them, you see the sealant turning solid, Caffélatex is working!

  7. What are the ingredients of the product and what happens if you drink a mouthful?

    1. Caffélatex contains synthetic latex and other chemicals, none of them classified as toxic.
