In 1991 Rex and Marilyn Trimnell got things started with X-Lite UK. After designing and manufacturing the world s first twin crown bicycle fork, Rex created a perfectly pink spray to clean his kit. To make a long story short, Rex s cleaner was the best thing since sliced bread, and it wasn t long before word got out and Muc-Off was born. Muc-Off is now the go-to brand for top riders and racers from the likes of Team Sky to Atherton Racing.
