Application: Cross Country, All Mountain, City & Touring Type: BSA Shell Width: 68/73 mm Axle Diameter: 24 mm (Hollowtech II)
Hollowtech II is using 24 mm axle and bearings. After studying all factors and testing, Shimano made the decision to adopt the 24 mm diameter axle and bearings to provide the best balance of rotating performance / stiffness / strength / sealing / weight in Shimano Quality.

The outboard bearings offer better weight distribution and more stability that provides a more efficient power transfer. The diameter of the bearing axle (24 mm) was an important factor in development because the axle has a positive effect on stiffness, stability, weight, and rotating efficiency.
