Wheels Manufacturing Inner Chainring Spacer

These spacers are designed to adjust the chain line for your inner chainring. They provide the necessary clearance to ensure your chainring is positioned correctly, which helps improve shifting accuracy and drivetrain efficiency.

These are designed for standard applications requiring an 8mm inner diameter. Before purchasing, verify that your crankset mounting hardware utilizes an 8mm bolt or post diameter to ensure a proper fit.

The 4.3mm thickness is a specific measurement intended to provide precise spacing for inner chainring alignment. It is crucial to match this thickness to your specific drivetrain requirements to avoid chain rub or misalignment issues.

6061 aluminum is chosen for its excellent strength-to-weight ratio and durability. It provides a secure, rigid interface that won't compress or deform under the torque of pedaling, ensuring your chainring stays firmly in place.

No, the 20-pack is intended to provide enough components for multiple installations, replacements, or custom builds. You only need to use the specific number of spacers required by your crankset's configuration.
