XLC CR-A03 Chain Tensioner

Chain tensioner with one derailleur pulley for single-speed hubs

Designed for single-speed hubs, the XLC CR-A03 chain tensioner is made of black aluminum and is suitable for 16-20 teeth with derailleur hanger mounting. The chain tensioner helps to prevent the rear wheel from automatically advancing and thus reduces the pressure on the chain. The CR-A03 chain tensioner has a chain line of 32 mm (6-38 mm) and C-C of 68 mm. The XLC chain tensioner is not suitable for bikes with coaster brakes, e.g. children's bikes, as these parts must be fitted in the same place on the bike.
