The original Shimano 12-speed quick link may be too narrow for this chainring.

We recommend replacing the original Shimano 12-speed quick link with another compatible 12-speed quick link, such as:

• Other compatible 12-speed quick links

This helps ensure smoother installation and better chain compatibility.
