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.

It's light, cheap and durable. Spins smoothly as well.
Excellent product.

Gut solange es funktioniert. Im Radkuriereinsatz hatte ich aber deutlich zu viele davon verschliessen. Werde das nächste Mal das XT Lager versuchen und hoffe, dass das zusätzliche Gewicht / Material auch zu verbesserter Haltbarkeit beiträgt.
