Parts and adapters for bottom brackets

Adapters and spare parts of the bottom brackets are designed to improve their compatibility and functionality. In the MTBIKER shop, you can choose from spare parts for central components such as:
  • Bottom bracket cups: These are threaded cups that screw into the frame and hold the bottom bracket in place. They come in various sizes and thread standards.
  • Bearings: Bearings are used for the smooth rotation of the crankset.
  • Washers/“Spacers” : A washer - “Spacer” is often used to fine-tune the chain line and ensure the correct setting of the cranks.
  • Adapters: Adapters are useful when you need to change the standard or sizes of the bottom bracket and adapt it to different types of cranks and frames.
Whether you need to replace worn components, achieve the correct chain line, or adapt to different frame standards, you will find the necessary parts and adapters here.
