Muc-Off launches tubeless tyre sealant line

New sealant will deal with holes up to 6mm and is cold-stable

Muc-Off says that it’s worked with pro road teams and downhill racers to develop its No Puncture Hassle sealant. It comes in a 140ml pouch that can be fitted over a presta valve stem to inject the sealant into a seated tyre without mess. You can also buy a one litre refill pack to refill the pouches.

The latex used is compatible with carbon dioxide tyre inflators and includes antifreeze to stop it balling up from the cold when using an inflator.
