Handmade tubular with latex inner tube inside, better protected by Caffélatex

Caffélatex works perfectly with ANY tubular.

Its complete lack of ammonia or aggressive chemicals make it benign even with very sensitive latex inner-tubes (like those found on professional level cyclocross tubulars, for example). Caffélatex is perfectly compatible with tubulars with butyl tubes or tubeless-tubulars construction (like Tufo).

If used inside tubulars, as their porosity is very little compared to a tubeless tire, Caffélatex lifespan (as a liquid) will easily exceed one year. This also applies to the lifespan of Caffélatex used as preventative inside simple inner tubes.

Once dried out, Caffélatex can’t be removed from the tubulars, but additional liquid Caffélatex can be added, to restore effective puncture protection.
There’s no problem in adding more Caffélatex, and there’s no negative interaction between dried-up (or partially dried-up) and fresh Caffélatex.

The best way to know there’s still liquid Caffélatex inside a tubular is letting the tubular sit for some minutes with the valve at the bottom then, without moving the tubular, opening the valve and gently squeezing the bottom of the tubular: if some CL gets out of the valve (or there’s some noise of liquid while squeezing the tubular), then the puncture prevention is still active. Be sure to clean the valve after that (just inflate with a pump, or remove the valve mechanism and dry the black rubber seal with a rag).

Recommended Caffélatex dosage inside tubulars:

  • road tubulars 28″-21, 28″-24: 30 ml
  • cyclocross tubulars 28″-28, 28″-33: 40 ml

  1. Hi,
    i have a Veloflex Roubaix with a very slow leak that i can’t locate. I’d like to keep it as a spare by using the Caffelatex to fix and then keep the tire folded under the saddle. Would this idea work?

    • Hi Chuck, while it’s certainly a good idea trying to fix the slow leak of your Veloflex tubular with Caffélatex, I’d avoid folding/storing it after that.
      Caffélatex might end up gluing the inner tube walls if the tubular is left for a long time tightly folded. Better repairing it and “finishing” the tubular, wearing out the rest of the tread.

    Hi, can you tell me how to inject (Caffélatex sealant )

    into a inner tube? should I let the air out of my bike. Then inject with required ammount?. i recently bought this product, and need to understand if i can use on a normal mountain bike wheel, with a normal inner tube?

    p.s if you can help me out that would be great. I purchased Caffélatex sealant an injector .

    Thanks for you time

    • Hi Matthew, yes: Caffélatex can also be used as a preventative inside inner tubes. To add puncture-protection to your inner tubes, completely deflate them, then inject the recommended Caffélatex quantity using the Injector. For any further question, let us know! The Effetto Mariposa Team.
