SLX Shadow plus 12-speed double rear derailleur for the ultimate in shifting performance and durability.

Shadow plus features a super low profile design and optimised slant angle for super light shifting action. It uses a chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting.

Single tension spring prevents contact with the chainstay resulting in a silent ride. Rubber bumper on pulley cage for added silent drive.
