The new Ultegra FC-R8100 crankset offers the same quick and precise crown gearbox and the efficient power transfer that the Shimano cyclists love, but with even more options for the length of the pagbella. With lengths from 160 to 175 mm, the Ultegra rods now also turn to smaller cyclists, triathics and those who want to try more shortcrumbs.
An integral part of the new 12V line from Strada Shimano, the FC8100 crankset is based on the legendary efficiency of the crown gearbox and Shimano broadcasts. With new improvements for a high fluidity 12V gearbox, the Ultegra cavella is now offered in lengths from 160 to 175 mm and offers more performance and compatibility for smaller cyclists, triathletes and cyclists with specific biomechanical requirements.
Characteristics:
- Optimal balance between rigidity, robustness, weight and rotation efficiency.
- The Hollowglide structure reduces the weight but maintains robustness, for a better power transfer and a faster and more precise crown change
- Corone combinations 52-36, 50-34 and 46-36. Pedesty lengths 160, 165, 170, 172.5, and 175 mm.
