The new ULTEGRA FC-R8100 crankset offers the same fast and precise shifting and efficient power transfer that Shimano riders love, but with even more crank length options. With lengths from 160 to 175 mm, ULTEGRA cranks now also cater to smaller riders, triathletes, and those wanting to try shorter cranks.
An integral part of Shimano's new 12-speed road line, the FC8100 crankset is based on the legendary efficiency of Shimano's shifting and drivetrains. With new refinements for smooth 12-speed shifting, the ULTEGRA crankset is now offered in lengths from 160 to 175 mm and provides more performance and compatibility for smaller riders, triathletes, and cyclists with specific biomechanical needs.
