- 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.
