Shimano 105 R7100 12 Speed Crankset

An attractive aluminum crank with hollow arms for lightweight, rigidity, and durability. The newly designed crank arms offer an optimized balance between stiffness, strength, lightweight and efficiency. The crank, formed with hollow aluminum technology, is anodized with a beautiful gloss black anodized finish, giving it a luxurious look. The resin ribs on the back of the chainrings are Shimano 105's unique structural design that achieves both weight reduction and crisp shifting performance. An integral part of Shimano's new 12-speed road lineup, the FC-7100 crank builds upon Shimano's legendary front shifting and transmission efficiency.
