Shimano manufactures a large assortment of different cranksets and bottom brackets. For every bike and discipline there is a matching system available. Press-Fit bottom brackets use axles and bearings with a diameter of 24 mm because it is the best combination of rotation efficiency, stiffness, load bearing, sealing, and weight that there is. The Hollowtech technology offers the follow: 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.Factory Number: I-SMBB7141A
