Caffélatex works perfectly with ANY tubular. Its complete lack of ammonia or aggressive chemicals make it benign even with very sensitive latex inner-tubes (Dugast’s superlight ones, for example)… so tubulars with butyl tubes or tubeless-tubulars construction (like Tufo) have nothing to fear of.
If used inside tubulars, as their porosity is very little compared to a tubeless tire, Caffèlatex lifespan (as a liquid) will easily exceed the one of the tubular (and last more than one year for sure, easily a couple of seasons). This also applies to the lifespan of Caffélatex used as preventative inside simple inner tubes.
Once dried out, Caffélatex can’t be removed from tubulars (it won’t moisten with water or other solvents), but additional liquid Caffélatex can be added, to keep tubulars protected against punctures.
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).
There’s no problem in adding more CL, and there’s no negative interaction between dried-up (or partially dried-up) CL and fresh CL.
Recommended Caffélatex dosage inside tubulars:
- road tubulars 28″-21, 28″-24: 30 ml
- cyclocross tubulars 28″-28, 28″-34: 40 ml
