Product Description The Ultegra FC-R8000 crankset by Shimano - elegant and powerful The Shimano Ultegra FC-R8000 11-speed crankset is characterised by its outstanding power transfer efficiency and can be easily used on road bikes with disc brakes and 135 mm over locknut dimension. With a uniform bolt circle diameter of 110 mm, four different chainring combinations can be mounted on the asymmetric 4-arm spider, resulting in a wide range of uses. As a Hollowtech crank with hollow-forged aluminium arms and featuring the Hollowtech II construction, the FC-R8000 offers an optimal stiffness-to-weight ratio. The hollow-shaped outer chainring also contributes to this. Last but not least, your road bike will also be visually enhanced by the Dura-Ace-like aesthetics of the Ultegra crankset.

It is based on an integration of the bottom bracket and the right crank arm and works with a 24 mm axle or bearing diameter, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside so that the load is better distributed. High-quality precision seals ensure a long service life.
