DISRAELI GEARS

Super JIC Course bronze

Super JIC Course derailleur main image

This derailleur was amazingly innovative. It is a proper parallelogram design, mounting on the drop out, with a low gear stop screw. With all this technology it came on to the market 8 years before Campagnolo’s Gran Sport.

Why is it a forgotten irrelevance? Probably because it was a single pulley design - and so doomed to uselessness.

The Super JIC Course is exceedingly similar to the Super-Inax Sport in this collection. They are clearly from the same manufacturer.
