Shimano Ultegra 12 Speed Cranks | FC-R8100 |

ULTEGRA's new FC-R8100 crank maintains the same fast, precise shifting and efficient power transfer that Shimano riders have become accustomed to, but with even more crank arm length options. Ranging from 160 to 175mm in length, the ULTEGRA cranks are now targeting smaller riders, triathletes, and those curious about shorter cranks.

An integral part of Shimano's new road 12-speed lineup, the FC8100 crank builds on Shimano's shifting and drivetrain efficiency. With the application of improvements to achieve a perfect 12-speed gearing, the ULTEGRA crank is now offered from 160 to 175mm, with improved performance and fit for smaller riders, triathletes and runners with specific biomechanical requirements.

• Optimum 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
• Chainring options of 52-36 and 50-34 and crank arm lengths of 160, 165, 170, 172.5 and 175mm.
