ULTEGRA's new FC-R8100 crankset offers the same quick, precise chainring changes and efficient power transfer that Shimano riders love, but with even more crank length options. With lengths from 160 to 175 mm, ULTEGRA cranks are now also aimed at smaller cyclists, triathletes and those who want to try shorter cranks.
An integral part of Shimano's new 12-speed road line, the FC8100 crankset builds on the legendary efficiency of Shimano chainring and drivetrains. With new refinements for smooth 12v shifting, the ULTEGRA crank is now offered in lengths from 160 to 175mm and offers more performance and compatibility for smaller riders, triathletes and riders with specific biomechanical requirements.
Characteristics:
- Optimal balance between rigidity, robustness, weight and rotation efficiency.
- HOLLOWGLIDE construction reduces weight but maintains strength for better power transfer and faster, more precise chainring changes
- Chainring combinations 52-36, 50-34 and 46-36. Crank lengths 160, 165, 170, 172.5, and 175 mm.
