Muc-Off No puncture Hassle Road & Gravel Tubeless Sealant, 140 ml - Tubeless Tyre Sealant voor Fiets Punctie Reparatie - Duurzame Fiets Band Sealant voor Weg-, Grint-, Forensen- en XC-fietsen

I have been happy with MucOff products especially their cleaners. This sealant does what it is supposed to do.

easy to use and works everytime. got a drawing pin stuck in my tyre, i pulled it out and it sealed straight away :-)

It's a new formula and it works to seal small holes quickly. I originally used Stan's which didn't work at all with road bike pressures. This Muc-Off sealed in seconds, but also struggled on every subsequent ride with pressures over 65psi on a relatively small hole. Searching for something that works better on road pressures .....

Does the trick? Just the amount of ml I squeezed in was confusing. Either I did it upside down or it is.

Sealant has partially solidified when arrived, the solid chunks are not visible when the pack is full as it is hidden inside the liquid. It ended up blocking my valve and I had to change the entire valve. The pack I received clearly has been opened before or been on the shelf for a long time.
