Caffélatex quantity: Road and Cyclocross

Tyre sealants are a must for the performance-oriented cyclist, to avoid unplanned stops before the finish line because of punctures. The big question is: how much sealant is the right quantity?

Parameters influencing the correct sealant quantity:

Several parameters should to be evaluated, for example:

  • external humidity
  • temperature
  • frequency of tyre inflation

… but the main factors are:

  1. Tyre size: section and diameter
  2. Tyre construction: if Tubeless, Tubeless-Ready, Tubular or Tube-type used as tubeless

With that in mind, we decided to calculate and provide our recommended sealant quantity: both as charts in this page and as a free App (for Android and iOS smartphones).

Sealant quantity and expected lifespan:

sealant lifespan inside tyres is directly related to the quantity. Reducing the quantity of sealant will reduce its ability to repair punctures, but also its lifespan. Sealant evaporation through tyre casing is unavoidable, and at a certain point there will be hardly any liquid inside the tyres, so no active puncture protection.
For this reason, regular checks and top-ups of sealant are strongly recommended.

Using our suggested quantities, the expected Caffélatex lifespan is:

  • Tubular (or Caffélatex inserted into latex/butyl inner tube): 1-2 years
  • UST  Tubeless tyre: 4-6 months
  • Tubeless-Ready tyre: 2-4 months
  • Tube-Type tyre (used as Tubeless): 2-3 months

  1. Q1. How do you recognized that the sealant is the new formula vs the old one. Are the bottle different?

    Q2. Does ZOT dries out when in the little bottle?

    1. Hi: Caffélatex formula changed at the beginning of 2012. If the batch number you read on the bottle starts with “12***” or more, it’s certainly the new formula. As for Caffélatex Zot!, it isn’t a fast evaporating product. Keeping it closed, it will last for years. Cheers!
