The Zefal Swan rear mudguard is ideal for road bikes and hybrid bikes that don't have the clearance for full mudguard mounts. While it wont keep you as protected as a fully integrated mudguard it will stop the spray covering your back.A width of 45mm means the Swan rear mudguard blends better with the narrower tyres you find on road bikes and sporty hybrids. The clamp will also fit any basic seatpost and is very easy to attach.Perfect for commuters in wet (not sloppy) conditions the Zefal Swan guard will keep you dry. Key features:Material: Technopolymer resinFixation: MD-Turn: On seat post, adjustable for 25 to 32mm diaBlade Width: 45mmWheel Dia: 700c / 28 inchWeight: 150g
