Description
The Shimano FC-R8000 52T Outer Chainring has a four-bolt asymmetrical pattern, with a 110mm Bolt Circle Diameter (BCD). That makes it the perfect replacement part for your Shimano Ultegra R8000 crankset. It's important to replace worn out chainrings to keep your drivetrain functioning smoothly. The aluminium construction keeps the weight of this component to a minimum while the HollowGlide technology ensures smooth shifting, lowering the risk of chain drop.
