Wheels Manufacturing Inner Chainring Spacer

These spacers are designed to fine-tune your drivetrain's chain line. By placing them behind the inner chainring, you can adjust the ring's position to improve shifting performance and ensure more efficient power transfer.

These spacers feature an 8mm inner diameter, which is standard for most chainring bolts. However, you should measure your existing setup to ensure the 3.5mm thickness provides the specific adjustment you need for your drivetrain geometry.

6061 aluminum is chosen for its excellent strength-to-weight ratio and durability. It provides the necessary rigidity to withstand the torque applied during pedaling without deforming, ensuring your chainring remains securely in place.

Not necessarily, but it is recommended to maintain consistency across the entire chainring. If you are adjusting your chain line, it is best practice to use identical spacers on all bolt positions to ensure the chainring remains perfectly parallel to the drivetrain.

Each bag contains 20 spacers. This quantity is ideal for shop mechanics or riders who are experimenting with multiple custom builds and need a reliable supply on hand.
