Shimano Alivio Rear Derailleur RD-M4000-SGS

The Shimano Alivio Shadow 9 speed rear derailleur is intended for more aggressive riding. Because of it's low profile and single tension construction, the derailleur does not hit the chainstay in rough riding conditions. The result is smooth and silent performance.
