Getting mud sprayed all over your back when you’re riding is fun. Ok, no, it’s not. But mudguards are often badly made, unsightly, and people generally tend to avoid them. If they had the Plume, pictured above, they might change their mind. Made from stainless steel and a flexible polymer, the Plume “extends out into a sleek mudguard or recoils back into a tight circle under your seat with the gentle press of a finger, even if you’re in motion.” The action is much like that of the snap bracelets of your youth, and doesn’t require springs, or any special mechanism. It’s $35, currently on pre-order on Kickstarter.
