Technologies

Hollowtech II

It is a crank inner bearing system designed to achieve an ideal ratio of rigidity, weight and rotational efficiency. It is based on an integration of the lower bearing and the right crank arm and works with an axle or with a 24 mm diameter inner bearing, 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. In addition, high-quality precision gaskets are added to ensure long service life.

Includes:

1 x Right cup with Shimano SM-BB71-41B bearing

1 x Left cup with Shimano SM-BB71-41B bearing

1 x Shimano inner bearing bushing
