Shimano CN-M8100 Deore XT 12-Speed Chain

Shimano chain for the named speed count (11- or 12-speed) — the wear-part in your drivetrain that determines both shifting quality and how fast the rest of the drivetrain wears out. A stretched chain eats cassettes and chainrings; running fresh chain matched to your cassette speed is cheap insurance. Deore XT is Shimano's second-tier MTB group — race-capable performance at a more accessible price than XTR; standard spec on high-end trail / cross-country builds. This is the Shimano CN-M8100 Deore XT 12-Speed Chain.
