Shimano - XTR RD-M9100-GS Shadow RD+ Rear Derailleur - 1x12-speed
In the small gears, a lower preload ensures that excessive chain tension is avoided. An additional stop on the rocker arm ensures a low-noise drive. The XTR 9100 rear derailleur's medium version features 28 mm more ground clearance than the long version. Unlike the RD-M9120 rear derailleur, the RD-M9100 is designed to work optimally with the XTR 1-speed drivetrain.
