The Shimano 105 FC-R7100 chainring is a 34-tooth inner ring built for 12-speed road drivetrains. It mounts to a 110mm BCD, 4-bolt asymmetric spider and retains a round profile for smooth, consistent power transfer through each pedal stroke across the full range of gear combinations riders use on varied terrain.
Machined from anodized aluminum, the ring features resin ribs on its back face to add rigidity while keeping mass low, with a claimed weight of 35 grams. It pairs with a 50-tooth outer ring, fits any Hollowtech II crankset, and runs smoothly with HG 12-speed chains for reliable shifting.
