The Shimano XTR RD-M9100 derailleurs are, like the other components of the XTR M9100 series, adapted to the respective Einsatzbreich: Enduro / Trail, XC or Marathon. So there are the rear derailleurs in versions with a long or medium cage for the use of a 1-fold or 2-fold drive. All rear derailleurs are distinguished by an elegant, yet aggressively angled design and attractive anodized aluminum surfaces. Among other things, large guide and tension rollers with 13 teeth ensure improved shifting performance. In addition, these also contribute to improving the chain stabilization as the Shadow RD + design with friction damper.
