Wheels Manufacturing Chainring Spacer

These spacers are designed to fine-tune your drivetrain's chain line. They are specifically used to adjust the position of the middle chainring, which helps ensure smooth shifting and optimal drivetrain efficiency.

These spacers feature a 10mm inner diameter and are specifically engineered for the middle chainring position. While the inner diameter is fixed, they are compatible with any crankset setup that utilizes a 10mm bolt interface for the middle ring.

While they are precision-machined from durable 6061 aluminum, they are specifically designed for chainring alignment. Using them for other components may not provide the necessary fit or structural integrity required for those specific applications.

Each bag contains 20 individual spacers. This bulk quantity is ideal for mechanics, frequent tinkerers, or anyone building up multiple bikes who needs a reliable supply of spares.

A 2.0mm thickness is a common standard for fine-tuning chain lines, but it is not universal. You should measure your current setup or consult your crankset manufacturer's specifications to confirm that a 2.0mm adjustment will achieve your desired chain line alignment.
