Technology:

Side-Swing
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.
