No more flats! Slime Tube Sealant seeks out and instantly seals punctures in your tubes up to 3mm. Install in your bicycle and enjoy two years of continuous flat tyre protection
When a puncture occurs, Slime's patented sealant is carried directly to the puncture. The pressure of the escaping air forces the particles into the opening, where they build up and intertwine to form a long-lasting, flexible plug. Instantly, air loss is blocked and a flat tyre is prevented
