Bottom Bracket SM-BB72-41B

Thanks to the reliable bearing and sealing elements from SHIMANO, the SM-BB72-41B bottom bracket has a particularly long service life. Press-Fit bottom brackets have axles and bearings with a diameter of 24 mm, because this results in the best combination of rotational efficiency, stiffness, load capacity, tightness and weight, even with press-fit bearings.
