Our NeoGuard is the original neoprene mudguard specially designed to protect you and your bike from mud. Traditional mudguards are fragile and can hold on to pounds of unwanted mud, affecting your driving performance and slowing you down. The NeoGuard mudguard sheds mud every time you press the fork, keeping your bike light and nimble.
