Taiwanese patent 201520126 - FSA main image

This 2013 Taiwanese patent developes the work done in Taiwanese Patent # 201121842 and Taiwanese Patent # 201136802. This particular patent adds electronics to the mix, in a style very reminiscent of the Tiso electronic derailleur. As such it provides the foundations for the FSA K-Force WE electronic derailleur.

The drawings depict a derailleur with an 'aero' pulley cage very similar to that used by FSA's sister brand Vision on the Vision Metron derailleur.
