Important Usage Notes
Quick-Link Requirement for Shimano 12s Road Chains
When using a Shimano 12-speed road chain, you must replace the original Shimano 12s quick link with another brand of the same 12s quick-link type. Shimano 12s quick links are too narrow for this chainring.
Compatible examples include KMC, YBN, SUMC, and other brands.
AXS 12s Flattop Chain Compatibility
This chainring does not support the SRAM AXS 12s flattop chain. If you need a custom tooth profile for SRAM AXS 12s flattop chains, please contact us to discuss customization (an additional surcharge applies).
