Shimano XT RD-M8120 12-speed Shadow Plus Rear Derailleur

XT RD-M8120 rear derailleur by Shimano - smooth and safe shifting everywhere

The Shimano XT RD-M8120 rear derailleur lets you shift a 10-45 cassette in a 1x12-speed or 2x12-speed system. It stands for precise and fast gear changes within a huge transmission range. Special features of this rear derailleur include 13-tooth sprockets and a rubber damper, which minimises noise and improves comfort. In addition, Shimano Shadow RD+ technology significantly increases chain retention.

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.
