SHIMANO Ultegra Di2 12-Speed Groupset

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. Spanning 160 to 175 mm in length, ULTEGRA cranks now cater to smaller riders, triathletes, and cyclists curious about shorter crank arms.

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. 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.

FEATURES
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
52-36 and 50-34 chainring options. 160, 165, 170, 172.5, and 175 mm crank arm lengths.
