The Shimano SLX CN-M7100 12-Speed Chain for all 12-speed. This chain has been thoroughly redesigned and is a central part of the SLX M7100 groupset. Precisely formed contact surfaces with the chainring and cassette teeth ensure fast, but also precise and smooth shifting up and down. Shifting with the CN-M7100 chain works perfectly even under load.
