Shimano 105 R7100 12-Speed Crankset

The Shimano 105 R7100 12-Speed Crankset is big on performance but low on price. The R7100 is finished with a durable, anodized gloss black coating while the HOLLOWTECH II structure reduces weight. In additions, stiffness is maintained for maximum power transfer. This crankset is available with 50/34T or 52/35T chainrings, which when paired with Shimano’s 12-speed cassettes provides ideal gearing for most road terrain.
