Shimano XTR RD-M9120 12-speed Shadow Plus Rear Derailleur

The XTR RD-M9120 Rear Derailleur by Shimano - Double Drivetrain

The Shimano XTR RD-M9120 rear derailleur offers the perfect solution when you want to ride a 2x12-speed drivetrain. This derailleur stands out with its large pulleys with 13 teeth that improve shifting performance, as well as an additional stop on the rocker for quiet operation. It also features Shadow+ clutch technology, where a stabilizer counteracts chain sag, slap and drop. Several pieces of the RD-M9120 are made out of a lightweight carbon. The XTR rear derailleur with its long cage (SGS type) is compatible with 10-45 cassettes.

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.
