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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eShimano Ultegra FC-R8100 Inner Chainring Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano FC-R8100 crankset (12-speed)\u003c\/li\u003e\n\u003cli\u003eAvailable sizes: 34t, 36t\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eDesigned for use with Shimano 12-speed road chains\u003c\/li\u003e\n\u003cli\u003eOEM replacement part for Ultegra 12-speed drivetrain\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"34t \/ Black","offer_id":43520609091628,"sku":"Y0NG34000","price":19.99,"currency_code":"USD","in_stock":true},{"title":"36t \/ Black","offer_id":43520609124396,"sku":"Y0NG36000","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-ultegra-fc-r8100-inner-chainring-1942661.jpg?v=1771297269","url":"https:\/\/ricycles.com\/products\/shimano-ultegra-fc-r8100-inner-chainring","provider":"RA Cycles","version":"1.0","type":"link"}
