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 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.

Works great but keep in mind the old Shimano Hollowtech wrench does not work on this. It needs a smaller diameter one (Shimano TL-FC37 or Park Tool BBT-590). You can also buy an adapter for the old wrench, but it comes in plastic: TL-FC-25. Pretty uncool to have to buy a new tool.

Обычная хорошая каретка, на замену дефолтному трешу - самое оно.
