Shimano FC-R8100 Chainring

Replacement chainring for the Shimano Ultegra FC-R8100 crankset — the current 12-speed generation of Shimano's second-tier road groupset. R8100 rings are profiled for the 12-speed Hyperglide+ chain and are not the same parts as the previous-generation R8000 rings sold separately; match this ring to an R8100 crank only. Sold as the specific position and tooth-count variant matching your crankset configuration; not a complete crankset.
