More Information

The Ultegra FC-R8100 keeps the quick, precise front shifting and efficient power transfer Shimano riders know, with an optimal balance of stiffness, strength, weight and rotational performance. It is an integral part of Shimano's 12-speed road lineup, with refinements for seamless 12-speed shifting.

The big news is the choice of crank arm length. Spanning 160 to 175mm, the Ultegra crankset now suits smaller riders, triathletes and cyclists curious about shorter crank arms, bringing better fit and comfort for specific biomechanical needs.

Compatibility

Shimano 12-speed HG chains and 12-speed road drivetrains. A HOLLOWTECH II crankset needs a Shimano HOLLOWTECH II bottom bracket – we stock the Ultegra BSA threaded (SM-BBR60) and press-fit (SM-BB71-41B) versions. Not sure which fits your frame? WhatsApp us.
