The Shimano 105 FC-R7100 is a highly developed bike crank designed specifically for use in road cycling. With its Hollowtech II technology, it offers excellent stiffness and low weight, leading to efficient power transfer while pedaling. The crankset features an asymmetrical bolt circle of 110 mm and supports a 12-speed drivetrain, allowing for precise and smooth gear shifts. The combination of aluminum for the crank arms and chainrings ensures durability and resilience, while the appealing black design provides a modern aesthetic. The crank is available in various lengths to meet the individual needs of cyclists.
