Rex and Marilyn Trimnell began things with X-Lite UK waaaay back in 1991. 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. Today, Muc-Off is now the go-to brand for top riders and racers.
