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
