Shimano Ultegra FC-R8000 Inner Chainring

Inner chainring for the Shimano Ultegra FC-R8000 crankset — the 11-speed generation of Shimano's second-tier road groupset, delivering close to Dura-Ace performance at a materially lower price. This is the smaller of the two rings, the one your chain lives on when the road tilts up; the matching R8000 outer ring and the newer 12-speed R8100 ring are separate parts. Sold as the specific tooth-count variant matching your crankset configuration; not a complete crankset.
