DISRAELI DOCUMENTS
This leaflet was handed out at Eurobike 2010, promising an electronic derailleur system for model year 2011. It is a rather stylish system with an angular facetted look and interesting digital readouts on the tops of the brake levers.
I believe the system was to work with Shimano and Campagnolo 11 speed cassettes and with Tiso’s own 12 speed cassette, which would be available for both Shimano and Campagnolo hubs.
This early prototype rear derailleur uses a parallelogram layout. This was replaced on later designs by a system more like that used by the SunTour Superbe Tech. I have a vague belief that this Tiso electronic derailleur is one of the grand parents of the FSA K-Force WE - you can trace the lineage through the relevant stream of patents.
