Sugino VIC

Sugino VIC derailleur main image

Designed to be a mass market indexed derailleur, the VIC is a steel monster vaguely reminiscent of the Huret Allvit. Unlike the Allvit, its parallelogram is made up of ‘three dimensional’ arms (like a SunTour Honor) rather than made up of flat plates (like a Huret Svelto), and the guide pulley moves forwards as it moves inwards. The basic geometry has many elements of a design of the SunTour Love (LV00) that SunTour patented (US patent # 4,789,379) in 1987. This geometry is quite interesting, promising the advantages of a slant parallelogram, without the torque across the parallelogram pivots. The VIC should have changed as well as a SunTour V and lasted as long as a Campagnolo Nuovo Record.

The price to pay for this sophistication is a lorra, lorra metal, as Cilla would say. Not a good way to keep down the weight on a low end steel gear. I believe it was a commercial disaster.

Finally the VIC is one of a select band of derailleurs which have the logo upside down for easy reading from low flying helicopters.
