The MarshGuard has been designed for and used by racers on the World Cup circuit in all disciplines from Cross country, Enduro and Downhill. It works by stopping the mud, and debris (that softer rubber tyres flick up) being brought through the gap between the lower crowns and wheel on suspension forks. It also protects fork stanchions and seals helping to extend fork service intervals. The MarshGuard has had more race wins than any other mudguard. The Marsh Guard doesn't come supplied with cable ties so you'll need four of these handy when you come to fit the product.
