Shimano XTR RD-M9100 12-speed Shadow Plus Rear Derailleur
Item number: 62127
The XTR RD-M9100 rear derailleur by Shimano - For 1x drivetrains
The XTR RD-M9100 rear derailleur was designed by Shimano exclusively for 1x12-speed drivetrains. It has enlarged 13-tooth derailleur pulleys for smoother operation and an additional stop on the swing arm that reduces noise. Of course, the Shadow+ damping technology is also used here, where a stabiliser counteracts sagging, slapping and dropping of the chain. Several pieces of the RD-M9100 are made out of a lightweight carbon. The XTR rear derailleur is available in two versions, namely with a shorter cage (GS) for 10-45 cassettes and with a long cage (SGS), which can shift 10-51 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.
