Shimano 12-Speed Quick Link Notice
If you are using a Shimano 12-speed chain, please note:
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:
- KMC
- YBN
- SUMC
- Other compatible 12-speed quick links
This helps ensure smoother installation and better chain compatibility.
