Overview
What Is the Shimano SM-CN910-12 Quick-Link For?
The Shimano SM-CN910-12 is the 12-speed chain quick-link (master link) for connecting and disconnecting Shimano 12-speed chains tool-free. Quick-links make chain removal for cleaning or replacement significantly faster than traditional chain pins. Snap the link together for installation. Quick-link pliers make removal easier. The SM-CN910-12 is sized specifically for 12-speed chains and is not interchangeable with 11-speed or other speed quick-links. Each link is single-use. Replace with a new quick-link every time the chain is removed.
Compatible with Shimano HG 12-speed chains: XTR CN-M9100, XT CN-M8100, SLX CN-M7100, and Deore CN-M6100. Dura-Ace R9200 uses the CN-M9100. Sold as 2 pairs for on-hand redundancy during maintenance.

FAQ
Good questions
Get to know Shimano

There's more to Shimano than this one product. Our Shimano page has the full Shimano lineup we carry and more about the brand.
Visit the Shimano page →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. Shimano lists the SM-CN910-12 for HG 12-speed chains only. For 11-speed chains, use the SM-CN900-11 quick-link. Shimano lists that link for HG 11-speed and LINKGLIDE chains.
Do I need special tools to install a quick-link?
No. Installation is tool-free: fit the quick-link and snap it closed with a firm pedal stroke. Removal is easier with quick-link pliers.
