Developed in collaboration with some of the world's top downhill and pro peloton teams, Muc-Off brings you the best tire sealant on the market. 'No Puncture Hassle' is compatible with tubeless-ready and full UST rims/tires. The 140ml pouches fit directly onto a Presta valve, making it clean and easy to use. If your valves do not have removable cores, you can simply pour the sealant directly into the tire. This advanced sealant contains cutting-edge microfiber molecules that fill larger holes and cracks, while the special latex instantly forms a strong seal inside the tire, providing excellent protection and effectively sealing the puncture site. Furthermore, 'No Puncture Hassle' features a unique UV detection system that highlights punctures you didn’t even notice while riding. It is biodegradable, non-corrosive on rims and tires, and can be washed off easily with water. The formula includes CO2-compatible latex and antifreeze agents to prevent clumping, a common issue with some sealants when used with CO2.
