The Shimano BB MT500 Bottom Bracket has outboard bearings offering better weight distribution and more stability providing a more efficient power transfer. The diameter of the bearing axle was an important factor in development because the axle has a positive effect on stiffness, stability, weight, and rotating efficiency. It is a press-fit Hollowtech II BB. It allows Hollowtech II-compatible cranks with 24 mm axles to be mounted on MTB frames with bottom bracket widths measuring 89 to 92 mm.
