An integral part of Shimano's new 12-speed road lineup, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency
ULTEGRA's new FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. With new refinements for seamless 12-speed shifting, the ULTEGRA crank is now offered in lengths from 160 to 175 mm, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements.
- Optimal balance of stiffness, strength, weight and rotational performance
- HOLLOWGLIDE structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting
