The Deore M6100 Shadow Plus 12-speed rear derailleur is awesome value for money and offers dependable shifting performance and durability.

Shadow Plus uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting. The single tension spring prevents contact with the chainstay resulting in a silent ride
