What matters is the overall balance of the crankset. With regard to the entire crankset, an optimum ratio between the strength of the crank arms, the stiffness of the axle, the bearing position and other features is very important. During the development of the crankset, the overall balance of all individual elements was carefully considered in order to ensure maximum stability.
Outer bearing: On most 68 mm bottom bracket housings, the Hollowtech II 24 mm axle can be mounted outside the frame for better weight distribution and stability.
High-quality precision seals: The Hollowtech II set also features high quality precision seals in the bearing area to extend durability and maintain excellent rotation efficiency over time.
The axle and the 24 mm diameter bearings ensure optimum balance of the crankset and optimum transmission of power to the bicycle.
