FAQ

Can I reuse a quick-link after removing my chain?

No. Shimano quick-links are single-use only. Each time the chain is removed and reinstalled, a new quick-link must be used. Reusing a quick-link risks premature failure during riding.

Is the SM-CN910-12 compatible with 11-speed chains?

No. The SM-CN910-12 is specifically sized for 12-speed chain widths. For 11-speed chains, use the SM-CN900-11 quick-link. The inner plate dimensions differ between speed counts.

Do I need special tools to install a quick-link?

Installation is tool-free -- feed the quick-link through the chain and snap it closed with a firm pedal stroke or gentle pull. Removal is easier with Shimano quick-link pliers or a chain breaker in reverse, though careful hand removal is also possible.
