Description
Shimano 105 FC-R7100 Inner Chainring | 12-Speed | 110 BCD 4-Bolt Asymmetric
The Shimano 105 FC-R7100 Inner Chainring is a genuine replacement ring for Shimano 105 R7100 12-speed road cranksets. If your inner ring is worn, has bent or missing teeth, or you want to refresh a well used drivetrain, fitting a matched Shimano ring is a straightforward way to bring back smooth, accurate shifting.
Made for the Shimano 105 R7100 12-Speed Crankset
This chainring belongs to Shimano’s 105 R7100 series and is designed for 12-speed drivetrains. Shimano’s chainrings are shaped to help the chain move between the inner and outer rings cleanly, so using the correct, matched ring helps keep front shifting crisp. It sits in the inner position of the crankset, and the listing covers the 34T and 50T ring combination used on the R7100 crankset.
110 BCD, 4-Bolt Asymmetric
The ring uses a 110mm BCD with a 4 bolt asymmetric Shimano pattern. Because the bolt layout is asymmetric, the ring only fits one way and only suits cranksets built to the same pattern, which helps keep it correctly positioned. Please check that your crankset uses this standard before ordering.
Why Replace a Worn Chainring
Chainrings wear with use, and worn teeth can cause skipping, poor shifting, and faster chain wear. Replacing the ring, and checking your chain and cassette at the same time, is often a simple and cost effective way to restore performance without buying a whole new crankset.
