Description

Some parts of this page are translated automatically, so please excuse any imperfections.

When you're grinding up a climb or pushing the pace on gravel, you want your cranks to spin smoothly without any annoying play. Shimano BB-MT501 bottom bracket cups help keep the drivetrain quiet, protected, and ready for more miles. Off-road, you’ll appreciate the confidence that your energy goes into pedaling—not into friction.

OEM product in non-original packaging.

Main benefits

The external-cup design with sealed bearings supports smooth crank rotation and stable power transfer when riding off-road.

Improved bearing sealing increases resistance to water, mud, and dust, helping the bottom bracket stay in good condition for longer.

Included are the right and left cups, an internal plastic sleeve, and spacers for precise fitment depending on the frame.

The unboxed version is practical for servicing and bike builds when you need a functional part without unnecessary extras.

Technical specifications

Model technical designation: BB-MT501.

Intended for MTB and trekking bikes with a bottom bracket for HOLLOWTECH II cranks.

The frame bottom bracket thread is the BSA standard with a diameter of 34,7 mm.

Compatible with a frame bottom bracket width of 68 mm or 73 mm and a 24 mm crank spindle diameter.

Conclusion

Shimano BB-MT501 is an external-cup bottom bracket that makes sense anywhere you want reliable performance and sensible maintenance. Thanks to its sealed bearings, it handles the dirt and damp from trails and roads better. If you’re building or servicing a bike with a BSA thread and HOLLOWTECH II cranks, you’ll get a solid foundation for smooth, confident pedaling.

Key features

  • External cups with sealed bearings
  • Compatibility with 24 mm crank spindle
  • BSA standard thread 34,7 mm
