Wheels Manufacturing Bottom Bracket Spacer

This spacer is designed to fine-tune your drivetrain setup. It is primarily used to adjust your chainline for better shifting performance or to eliminate unwanted side-to-side play in your bottom bracket bearings.

While this spacer is built to standard specifications, compatibility depends on your specific crankset and bottom bracket shell width. It is designed for standard systems, but you should verify your current setup's clearance requirements before installation.

Aluminum offers superior durability and compression resistance compared to plastic alternatives. This ensures that the spacer maintains its precise thickness over time, preventing your bottom bracket from developing play or creaking under load.

You typically need a spacer if you are experiencing chainline misalignment or if your crankset has lateral movement after installation. If you are unsure, measure the gap between your crank arm and the bottom bracket cup to determine if 1.8mm is the correct thickness to close that space.

Yes, you can stack spacers if necessary to achieve the correct width. However, ensure that you have sufficient spindle length on your crankset to safely engage the non-drive side crank arm after adding the extra width.
