The Shimano XT front derailleurs FD-M8025 and FD-M8020 - from classic to innovative


The Shimano XT front derailleurs FD-M8020 and FD-M8025 shift two chainrings in the 11-speed Mountain bike drivetrain and contribute significantly to the DynaSys11 performance. The FD-M8025 is a model with classic cable routing (dual-pull or down-pull) and conventional construction (down-swing or top-swing), while the FD-M8020 features innovative side-swing technology and the associated front-pull routing. These provide a higher shifting force and even more tyre clearance. Mounting options include clamp mounts, direct mount and E-type for both models.

Technology:


Dyna-Sys11
The real advantage of the 11-speed drivetrain is that the entire range of ratios is available without having to give up the usual rhythm. Dyna-Sys11 ensures an optimal rhythm both in the flats and in the ascents with " Rhythm Step" gears in the most frequently used range. Drive efficiency is a critical performance indicator for the drivetrain. Dyna-Sys11 means more speed with the same effort.

Side-Swing (FD-M8020 only)
The so-called Side-Swing technology delivers 90% better shifting performance. Developed with particular regard to modern bikes, the Side-Swing derailleur offers 15 % more space between seat tube and tyre, while the completely new and optimised cable pull and cable routing drastically reduces the force needed to operate the shifter.

Super Qualität, einfach u. exakt einzustellen. Schaltperformance an XT-M 8000-2 Kurbel mit 24/36. Hatte nach Umrüstung von 10-auf 11-fach den 10 fach Umwerfer FD-M 786 gelassen. Funktionierte auch, war aber schwerer einzustellen mit schmalem Grenzbereich zum "Überwerfen". Mit dem FD-M 8025-D um Welten besser. Einstellung passt auf Anhieb u. die Schaltkräfte sind deutlich geringer als mit dem 10-fach Umwerfer. Die 12 Zähne (24/36) wechselt er problemlos, spüre keinen Unterschied zu 26/36. Noch nie so schnell u. leise die Kette "umgeworfen". Tolles Produkt bekommt von mir volle 5*.
