We have worked closely with German company SKS who manufacture some of the best mudguards (fenders) around. We wanted to have satin black fixing rods and mudguards that custom fit the Vielo frame and fork mounts without having to bend, cut or modify. The result is a mudguard, when mounted on the bike, you can hardly see, its nearly invisible. No annoying rattles or wobbles. No ugly bridge between the seat stays. There is enough clearance to accommodate 700c x 42mm tyres and 650b x 47mm tyres.
