Shimano Deore RD-M5120 10/11-speed Shadow Plus Rear Derailleur

Shimano Deore rear derailleur RD-M5120 - can take 10-speed sprockets up to 46 teeth

The Shimano Deore RD-M5120 rear derailleur can be combined with 2x10-speed and 2x11-speed drivetrains as well as 1x10-speed drivetrains. It is designed for 42 tooth on the largest cassette sprocket when using a drivetrain with two chainrings, and can handle up to 46 teeth on the largest sprocket when using a 1x set-up. The rear derailleur features Shadow+ clutch technology, where a stabilizer counteracts chain sag, slap and drop. RD-M5120 is either mounted via a standard derailleur hanger or directly.

Features:

• low-noise drivetrain in all switching positions
• reduced tension of rear derailleur and chain in low gears
• compact profile limits damage from rocks and roots
• chain stabilizer (Shadow+) against chain drops, chain slaps and noise
• painted cage plates
• 4 pivot bushings, fluorine-coated

Technology:

Shadow RD+
Shadow Plus rear derailleurs are just as low-profile as Shimano's Shadow rear derailleurs. In addition, a stabilizer with on/off switch is used to reduce chain slap and thus counteract chain drop. At the same time, this results in a quieter drive. Weight is also saved compared to other chain restraint devices.
