The Ultegra FC-R8000 crankset by Shimano - elegant and powerful
The Shimano Ultegra FC-R8000 11-speed crankset features outstanding power transmission efficiency and can easily be used on Road bikes with disc brakes and an 135 mm over locknut dimension. With a uniform bolt circle diameter of 110 mm, four different chainring combinations can be mounted on the asymmetrical 4-arm spider, resulting in a wide range of applications. As a Hollowtech crank with hollow forged aluminium arms and Hollowtech II construction, the FC-R8000 offers an optimum stiffness to weight ratio. The hollow outer chainring also contributes to this. And last but not least, your Road bike will also be visually enhanced by the Dura-Ace-like aesthetics of the Ultegra set.

A lightweight crankset not only reduces the bike's weight, but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity. Shimano's advanced forging technology has solved the problem through the Hollowtech crank. Just like high quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at very light weight.

Hollowtech II
What matters is the overall balance of the crankset. With regard to the entire crankset, an optimum ratio between the strength of the crank arms, the stiffness of the axle, the bearing position and other features is very important. During the development of the crankset, the overall balance of all individual elements was carefully considered in order to ensure maximum stability.
Outer bearing: On most 68 mm bottom bracket housings, the Hollowtech II 24 mm axle can be mounted outside the frame for better weight distribution and stability.
High-quality precision seals: The Hollowtech II set also features high quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency over time.
The axle and the 24 mm diameter bearings ensure optimum balance of the crankset and optimum transmission of power to the bicycle.

Hollow outer chainring: The extremely stiff hollow structure reduces the weight while maintaining the same strength. Better power transmission and faster, more precise front shifts (not with 46 tooth).
