There are a number of different options when it comes to which sealant to use in your tubeless road tyres or mountain bike tyres.

The best tubeless sealants in 2023
Effetto Mariposa Caffélatex

4.5 out of 5 star rating

Effetto Mariposa offers additives that are said to make the Caffélatex sealant more effective. 
The Effetto Mariposa Caffélatex is one of the cheapest and most effective tubeless sealants.

The low-viscosity foaming solution plugs hard-to-reach sidewall punctures with the least air loss. It sealed holes made by a 6mm screwdriver with 10psi air loss.

But the Effetto Mariposa Caffélatex couldn’t plug a 6mm hole as quickly as Stan’s Race Sealant.

Nor could the sealant block a hole made by an 8mm screwdriver, but that’s not uncommon.

Additives are available from Effetto that are claimed to increase the effectiveness of Caffélatex with larger holes, though (V-CL)
