Shimano Ultegra FC-R8100 Inner Chainring
Shimano Ultegra FC-R8100 Inner Chainring Info
The Shimano Ultegra FC-R8100 Inner Chainring is the direct replacement inner ring for Shimano's 12-speed Ultegra crankset, designed to maintain the precise shifting performance the FC-R8100 system is built around. Available in 34t and 36t options, it gives you the ability to fine-tune your gearing setup or restore a worn ring without replacing the entire crank.
The FC-R8100 chainring is engineered specifically for Shimano's 12-speed road groupset, meaning it is intended to work with Shimano 12-speed chains and the corresponding outer ring — not a universal fit. If you're running the Ultegra 12-speed crankset and chasing consistent, reliable shifts across a full season of riding, keeping the drivetrain running on OEM-spec components is the straightforward approach.
