An integral part of Shimano's new 12-speed road lineup, the FC8100 crank builds on Shimano's shifting and drivetrain efficiency. With the application of improvements to achieve a perfect 12-speed shifting, the ULTEGRA crank is now offered from 160 to 175mm, with improved performance and fit for smaller cyclists, triathletes and racers with specific biomechanical requirements.
・Optimal balance of stiffness, strength, weight, and rotational performance.
・HOLLOWGLIDE construction reduces weight but maintains strength for better power transfer and faster, more precise front shifting
・52-36 and 50-34 chainring options and 160, 165, 170, 172.5 and 175mm crank arm lengths.
