Deore M593 SGS 10 speed Shadow Rear Derailleur

Shimano's Deore line has always meant reliable performance at a price that still left money in your pocket. For 2012 the Deore line gets a Dyna-Sys 10 speed option. The Dyna-Sys system is just upgraded by adding the additional gear, but also a revised cable pull for smoother quicker shifting.

• Shimano Shadow rear derailleur technology reduces chain slap and jockey wheel roll resistance
• Works with all Shimano Dyna-Sys shifters
• Does not work with Shimano 8/9 speed or any Sram shifter.
