Longevity of tube sealant

It’s amazing how most of you folks keep talking about tubeless sealant, even though the OP more than once said that he’s talking about sealant inside tubes.

Two very different setups.

I can’t recall a sludge filled tube ever actually stopping a puncture, to be honest… Used it for years and got punctures at the same rate, until tubeless became a thing.

 

The Sludge brand as discussed WORKED in our bikes for years - inside tubes.

 

BUT it works at the LOWER pressures of MTB tyres.  It is not effective at gravel tyre pressures, never mind road pressures.

 

 

This where my experience with sealants IN TUBES end.
