Shimano Deore FD-M6020 / FD-M6025 2-/10-speed Front Derailleur

The Shimano Deore front derailleurs FD-M6020 and FD-M6025 offer a wide range of choices

The Shimano Deore front derailleurs FD-M6020 and FD-M6025 ensure smooth chainring changes in 2x10-speed MTB drivetrains. The FD-M6025 is available with conventional down swing and top swing construction as well as cable routing from below or from both directions. In contrast, the FD-M6020 is a side-swing model with a novel design for even more tyre clearance. The front-pull cable routing ensures maximum efficiency with minimum operating forces. The mounting options are not only high clamp , low clamp, E-type and direct mount, the FD-M6020 for the first time also uses the mid-clamp option. This optimises the weight-function ratio and improves the optics.

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.
