Model SC-CC-103 is a bicycle half chaincover, a chain guard for the chain and front chainring. A chain cover keeps the rider's clothing clear of the chain and its grease. This version has a solid, glossy black body with a moulded groove along its length and concentric raised rings around a round opening at the wide end. It carries a gold "SONA" logo and a thin contrasting pinstripe along the edge. Part numbers: SC-CC-103
