Technology:

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 lower bearing and the right crank arm and works with a 24mm diameter spindle or bottom bracket, which has proven to be optimal in terms of stability. In many cases, the bearing cups are on the outside for better load distribution. In addition, high-quality precision gaskets are added to ensure a long service life.
