Shimano Ultegra FC-08 HTII cranks

The Shimano Ultegra FC-08 cranks are the successor to the R6800 and R8000 Ultegra cranks and offer the same benefits as the R8000 model. They belong to Shimano's new Ultegra R8000 series, which includes many of the features of the Dura-Ace series in a more affordable package. The crank arm is larger and provides significantly better power transfer compared to previous versions. In addition to technical improvements , the design has also been redesigned for an elegant and attractive appearance.
