An integral part of Shimano's new 12-speed road line, the FC8100 crankset builds on the legendary efficiency of Shimano chainrings and drivetrains. With new refinements for high-fluidity 12-speed shifting, the ULTEGRA crankarm is now offered in lengths from 160 to 175 mm and provides more performance and compatibility for smaller riders, triathletes, and cyclists with specific biomechanical requirements.
- Optimal balance of stiffness, durability, weight, and rotational efficiency.
- HOLLOWGLIDE construction reduces weight while maintaining durability, for better power transfer and faster, more precise shifting
- Chainring combinations 52-36, 50-34, and 46-36. Crankarm lengths 160, 165, 170, 172.5, and 175 mm.
