Hollowtech II

The concept of Hollowtech II technology was designed to produce an optimized crankset that minimizes the amount of power the rider needs to pedal. The high stiffness of the crankset ensures the efficiency of power transmission when pedaling, while its light weight relieves the rider, especially on longer distances. The crankset was developed with an optimal balance between stiffness, rotational efficiency, light weight and attractive appearance in mind. Hollowtech technology allows for extremely lightweight, hollow crank arms that are manufactured using Shimano's exclusive forging technology to achieve maximum stiffness. In addition, the Hollowtech II crankset has the right crank firmly connected to the axle of the bottom bracket, achieving an optimal balance between maximum stiffness and minimum weight. The externally mounted bottom bracket offers a better weight distribution and more stability, which ensures a more efficient power transmission.
