Dirtsurfer have designed a road and gravel specific mudgaurd. The mudguard fits under the saddle, preventing spray from the rear wheel. Dirtsurfers simple yet robust design will keep the mud and muck away. This helps to prolong the lifespan of your bike as less muck finds its way into your bike. It also helps keep you clean from all the spray that is flicked up from the rear wheel. Dirtsurfer mudguards have been specially designed to protect you by deflecting the water, mud and crud (whatever form that might be) that is thrown up from your tyre. Dirtsurfer designed them to install using invisible fixings which make for a very svelte look.
