The FC-R8100 crankset is an integral component of the Shimano Ultegra 12-speed road lineup, elevating front shifting and transmission efficiency. Designed with new refinements for seamless 12-speed shifting, it now offers a range of lengths to accommodate smaller riders, triathletes, and those with specific biomechanical requirements. This crankset strikes an optimal balance in stiffness, strength, weight, and rotational performance. Its Hollowglide structure effectively reduces weight while maintaining strength, ensuring improved power transfer and quicker, more precise front shifting. With a 148mm Q-factor and a 44.5mm chainline, the Ultegra FC-R8100 crankset delivers enhanced performance and an improved fit for a diverse range of riders.
