Why does the CN-M8100 ship with 138 links instead of 126?

Shimano ships this chain at 138 links to accommodate a wider range of bike configurations and crank/chainring combinations. You will shorten it to the correct length for your specific setup during installation.

Is the CN-M8100 compatible with XTR or SLX 12-speed?

Yes. All Shimano 12-speed MTB chains are cross-compatible within the HYPERGLIDE+ ecosystem. The CN-M8100 works with XTR M9100, SLX M7100, and Deore M6100 12-speed groups.

Does the Quick-Link allow the chain to be reused after removal?

Shimano Quick-Links are designed for single use. If you remove the chain for cleaning or maintenance, replace the Quick-Link before reinstalling.
