Shimano SLX Dyna-Sys CN-HG74 Chain - 10-Speed Component Group

Product Description

Shimano designed the SLX Dyna-Sys CN-HG74 10-speed chain to match perfectly with its new 10-speed mountain drivetrain. This narrow chain shifts more smoothly than chains designed for 9-speed systems because of the tighter spacing on the 10-speed cassette.
