Caffélatex – bicycle tyre sealant

Caffélatex tyre sealant is quietly hiding in the wheels of the best cyclists in the World, who trust it to ride as puncture-free as possible. With a strong racing background in road and off-road cycling, Caffélatex is perfect for tubeless, tubular and inner-tube applications.



  • Very fast puncture repairing action, ideal for performance-oriented cyclists (and for those who want even more, we created Vitamina CL additive)
  • Adds very little weight to wheels, following the suggested quantities (see iCaffelatex app)
  • Its foaming behavior makes it spread evenly inside tyres, covering the whole internal surface very efficiently
  • Caffélatex doesn’t contain ammonia or other aggressive chemicals and is not toxic
  • Relying on synthetic latex, Caffélatex doesn’t create allergy issues associated with natural latex


Very fast puncture repairing action

A secret blend of liquid synthetic polymers gives Caffélatex its “latex-like” behavior, becoming solid when exposed to fast evaporation, repairing holes in the process. We improved this with the addition of a precise percentage of microscopic (less than 2 microns, 0,002 mm) silicate particles, so that Caffélatex moves slowly through holes, allowing it more time to heal the puncture.

Puncture repair speed is especially beneficial with lightweight or thin-casing tyres, making Caffélatex ideal for performance-oriented cyclists, for both road and off-road cycling and for tubeless, tubular and inner-tube applications.
Caffélatex repairs punctures up to 5 mm (off-road tubeless tyres) and 3 mm (road tubeless tyres).

For cyclists seeking the ultimate puncture protection, we created for Caffélatex the Vitamina CL additive.

In order to save weight on rotating masses, Caffélatex has a high mobility and a small quantity goes a long way in terms of coverage of the inner surface of the tyre. We suggest to use the quantities suggested by the iCaffelatex app or in the table here: while too much sealant is unnecessary weight, too little is utterly pointless as punctures will still occur and the (small) weight of sealant will serve no purpose. 
For example, we recommend 60 ml (approximately 2 oz) of Caffélatex for 29×2.10 (54-622) tubeless tyres; 30 ml (approximately 1 oz) for 700x25c (25-622) tubeless tyres.

Foaming behavior activated by wheel movement

When engineering Caffélatex and refining its formula, we discovered that providing it with a foaming behavior (passing from liquid to foam when agitated, so activated by wheel movement) was a big plus in terms of ability to spread inside the tyre cavity. When wheels are turning, centrifugal force drives standard liquid sealants against the outer circumference inside the tyre.

Caffélatex, turning into foam, tends to fill the entire internal cavity of the tyre, making Caffélatex available and effective even when the puncture happens on the sidewall. Caffélatex reverts to its liquid state after around 15 minutes of stillness.


Compared to other “latex-like” sealants, Caffélatex is a very stable and durable, although its lifespan is heavily influenced by tyre type.

Using the recommended quantity for tyre size/type, the expected Caffélatex lifespan is:

  • Tubular (or Caffélatex 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

In the impossibility of knowing the specific conditions (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 ensures its puncture preventive action.
When dry, Caffélatex-sealed wheels are still air-tight, but Caffélatex won’t actively repair punctures.

Not toxic, corrosive, allergenic

Caffélatex doesn’t contain ammonia or other aggressive chemicals: that characteristic makes it also the favorite sealant for cyclocross/tubular applications, creating no harm to the sensitive latex inner tubes. 

WARNING: oxidation of aluminum rims can happen because of the water content of the sealant, occurring where metal surface is not painted/protected or covered by tubeless rim strip or tape.

As its formula is synthetic, Caffélatex doesn’t trigger allergic reactions in people who are allergic to products made with natural rubber latex.


Caffélatex is available as bottles of 1000 or 250 ml. Ten liter Caffélatex Pro Point cube is a great choice for teams or shops.

Usage and storage temperatures and tips

Usage: -20/+50°C (-4/+122°F)

Storage: -15/+30°C (+5/+86°F)

Caffélatex will last 2 years after the bottle is first open, as long as the bottle is closed properly and stored away from direct sunlight, and the storage temperature is within the range stated above.

To check if a bottle of Caffélatex is still good, even after a long time since first opening it:

  • the liquid should have a homogeneous viscosity (no solid chunks or evident separation between lighter and denser liquid);
  • 10-second test: wet thumb and index in liquid Caffélatex, press it between the two fingers for ten seconds then release: if it starts to create a solid layer, it’s still functioning properly.

  1. Hello

    I storaged a set of set of Continental Competition tubulars tires deflated with Caffelatex inside. Now, both tires have a chunk of dried sealant inside, and when inflated them again, are out of balance.
    Is there a way to dissolve the dried Caffelatex?

    Thanks in advance!

  2. Hi,

    “we recommend checking Caffélatex every 2 months, to make sure it’s liquid ”

    What is the best way for checking the Caffélatex in the tyre? Is there a good way to check without unseating the tyre from the rim?

    Thank you

    1. Hello,
      unfortunately there isn’t a way to assess the residual quantity (and status) of sealant inside tyres without unseating them. Some methods, relying on little straws sucking the sealant out through the valve, have a strong tendency to clog in the process, so there isn’t one we can recommend. Sorry!

  3. If i have a bottle of caffelatex sitting on the shelf for a month or more should i shake the bottle to remix the contents before adding to a tyre ?

    1. This is a good questions, thanks for asking. You don’t need to shake the bottle of Caffélatex: it’s sufficient to turn the bottle upside down a couple of times to make sure it’s homogeneous when you add it to a tyre.

  4. Who is the distributor in Brazil?
    I own a bike shop here in Brazil and would like to work with the products.

  5. 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.

  6. 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.

    2. Follow-up question: Sealant dries, you refill, sealant dries, you refill… Doesn’t that mean that the tyre/wheel will become heavier and heavier?

      1. Thanks for the interesting question!
        In theory, yes, if you continue topping-up sealant, you will end up with a lot of dried up sealant inside your tyres, carrying unnecessary weight.
        In reality this very seldom happens for two reasons:
        – it’s easy – from times to times – to open the tyre and remove the bigger chuncks of solid sealant (instant weight saving);
        – tyres wear out, and most people won’t need to refill tyres more than a couple/three times before they have to replace them.

  7. 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?

  8. Would caffélatex work with the valve extender (valve stem core is inside the extender)?

    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.

  9. 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!

  10. 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.

  11. 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!

  12. 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.
      In case of skin contact: Wash with plenty of water and soap.
      In case of eyes contact: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
