Technology:
Hollowtech II
In the Hollowtech II crankset, the right crank is firmly connected to the bottom bracket axle, achieving an optimum balance between maximum stiffness and minimum weight. The externally mounted bottom bracket offers better weight distribution and stability for more efficient power transmission. Why a 24 mm diameter bottom bracket? The diameter of the bottom bracket axle and the bearings was an important factor in the development, as the bottom bracket axle has a significant impact on stiffness, stability, weight and rotational efficiency.
