Shimano Ultegra FC-R8100 Crankset – 52-36T

The Shimano Ultegra FC-R8100 crankset offers the same fast and precise chainring shifting and efficient power transfer that Shimano cyclists love, but with even more crank arm length options. With lengths from 160 to 175 mm, the ULTEGRA crank arms now cater to smaller cyclists, triathletes, and those looking to try shorter crank arms. An integral part of Shimano’s new 12-speed road line, the FC8100 crankset builds on the legendary efficiency of Shimano’s chainring and drivetrain. With new refinements for high-flow 12-speed shifting, the ULTEGRA crank arm is now offered in lengths from 160 to 175 mm and provides more performance and compatibility for smaller cyclists, triathletes, and cyclists with specific biomechanical requirements.
