Shimano Ultegra FC-R8000 11 Speed ​​Bike Crankset 53/39T 172.5mm IFCR8000DX39

The Shimano Ultegra FC-R8000 11-speed crankset is characterized by its outstanding power transfer efficiency and can be easily used on road bikes with disc brakes and over 135mm nut size. With a uniform bolt circle diameter of 110 mm, four different chainring combinations can be mounted on the asymmetrical 4-arm spider, providing a wide range of uses. As a Hollowtech crank with hollow forged aluminum arms and Hollowtech II construction, the FC-R8000 offers an optimum stiffness-to-weight ratio. The hollow-shaped outer chainring also contributes to this. Finally, your road bike will also be visually enhanced with the Dura-Ace-like aesthetic of the Ultegra crankset.
