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

Shadow plus features a super low profile design and optimized slant angle for super light shifting action.

Shadow Plus 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. 13T pulleys and decreased derailleur tension prevent high chain tension in low gears.
