ULTEGRA's FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. An integral part of Shimano's 12-speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency.
