The Shimano CN-M8100 is designed for modern Shimano 12-speed drivetrains and combines precise shifting with excellent durability.
Its dedicated HYPERGLIDE+ design guides the chain precisely across the cassette and chainring during shifting. This allows smooth and controlled gear changes even when high pedalling loads are applied.
The extended inner plate design improves engagement with Shimano 12-speed chainrings and cassette sprockets and provides stable chain retention on rough terrain.
Although the CN-M8100 is part of the Deore XT M8100 family, it is also used with several Shimano 12-speed road and gravel groups.
