More Information

Chainrings wear with use, and a worn or bent ring hurts shifting. These genuine Ultegra R8100 rings let you replace just the outer or inner ring instead of buying a whole new crankset, or switch between the 50-34T and 52-36T gearing.

Shimano chainrings are designed as matched pairs, so always fit 50T with 34T, or 52T with 36T.

Compatibility

For the Shimano Ultegra FC-R8100 12-speed crankset (110mm BCD, 4-arm), used with 12-speed HG chains. Not for other cranksets – WhatsApp us your crankset model if you are unsure.
