The Deore rear derailleur RD-M4120 has been designed by Shimano for both 2x10-speed and 2x11-speed drivetrains in MTB and City & Touring applications. The largest cassette sprocket must have 42 teeth and the difference between the chainrings must not exceed 10 teeth. Thanks to its flat " Shadow" design and simple pre-tensioning, the rear derailleur does not hit the chainstay even on rough surfaces.
