DESCRIPTION
The all-new SHIMANO ULTEGRA R-8170 groupset delivers the power transfer that Shimano riders love, but with even more crank length options.
COMPOSITION
SHIMANO ULTEGRA HOLLOWTECH II FC-R8100 172.5mm 2x12-speed crankset
The new ULTEGRA FC-R8100 crankset offers the same fast, precise chainring shifting and efficient power transfer that Shimano riders love, but with even more crank length options. With lengths from 160 to 175 mm, ULTEGRA cranks now also appeal to smaller riders, triathletes, and those looking to try shorter cranks.
Part of Shimano's new 12-speed road lineup, the FC8100 crankset builds on the legendary efficiency of Shimano's chainrings and drivetrains. With new refinements for smooth 12-speed shifting, the ULTEGRA crankset offers more performance and compatibility for smaller riders, triathletes, and cyclists with specific biomechanical requirements.
- Optimal balance between stiffness, strength, weight and rotation efficiency.
- HOLLOWGLIDE construction reduces weight but maintains strength, for improved power transfer and faster, more precise chainring shifting
