Hollowtech II: Shimano Hollowtech II is a crank bottom bracket system designed to achieve an ideal ratio of stiffness, weight and rotational efficiency. 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.;

The Ultegra FC-R8100 Crankset by Shimano - For highly efficient power transfer The Shimano FC-R8100 crankset converts the power you put into your Ultegra 2x12-speed road bike groupset into propulsion with high efficiency. Thanks to the proven Hollowtech II design, it meets all your requirements for stiffness and stability. You also benefit from the precise and fast shifting processes you are used to from Shimano drives. The crank arms are hollow-formed, as is the large chainring, which is partly made of carbon, resulting in significant weight savings. Apart from the axle, all essential parts were made of lightweight metal. FC-R8100 has an asymmetrical 4-arm bolt circle diameter of 110 mm. It produces a chainline of 44.5 mm and has a Q-factor of 148 mm.
