FC-R8100 Crankset Shimano 12s 52-36t

An integral part of Shimano's new 12-speed road line, the FC8100 crank builds on Shimano's shifting and drivetrain efficiency.

With improvements made to achieve perfect 12-speed shifting, the Ultegra crank is now offered from 160 to 175mm, with improved performance and fit for smaller riders, triathletes and riders with specific biomechanical requirements. 

• Optimal balance of stiffness, strength, weight and rotational performance.
• Hollowglide structure reduces weight but maintains strength for better power transfer and faster, more precise front shifting
• 52-36 and 50-34 chainring options and crank arm lengths of 160, 165, 170, 172.5 and 175 mm.
