Wheels Manufacturing Bottom Bracket Adaptor

This adaptor is specifically engineered to fit 24mm spindle cranks. It is primarily designed to allow you to run these cranks in frames that use the BBRight bottom bracket standard.

Installation is generally straightforward and typically does not require specialized proprietary tools, though you should have standard bottom bracket tools on hand. Because it acts as a shim, it presses or slides into place to bridge the gap between your frame's shell and the crank spindle.

While this adaptor is designed for precise fitment, creaking is often caused by tolerance issues or contamination. If your current setup is creaking, ensure your bottom bracket shell is clean and properly greased before installing the adaptor to minimize the risk of noise.

The compatibility is determined by the spindle diameter rather than the discipline. As long as your crankset utilizes a 24mm spindle, this adaptor will function correctly regardless of whether it is a road or mountain bike component.

In most cases, the adaptor is designed to fit without extra spacers, but it depends on your specific crankset's chainline requirements. Always check your crank manufacturer's instructions to see if specific preload spacers are required on the drive or non-drive side.
