Shimano XTR FD-M9100 2-/12-speed Front Derailleur

The XTR front derailleur FD-M9100 by Shimano - compatible with different chainlines

The Shimano XTR FD-M9100 front derailleur for 2x12-speed drivetrains impresses with its special side-swing design and the associated front-pull routing with large tyre clearance, maximum shifting efficiency and low operating forces. It can be used for cranks with standard chainlines as well as for cranks with chainlines 3 mm further out. In addition to an E-type and a direct mount version, there is also a version with a mid-clamp position to choose from.

Technology:

Side-Swing
The Shimano Side-Swing front derailleurs are controlled from the front (Front-Pull), which allows for much more efficient cable routing. This significantly improves shifting performance, especially when shifting to the large chainring - with lower operating forces. Other advantages include increased tyre clearance thanks to the slimmed-down design and noise reduction thanks to the optimised chainstay angle. In addition, Side-Swing technology favours the construction of frames with shorter chainstays, which simplify the control of the bike.
