That Suntour had been rewarded for their fair business practices and brilliant products... and didn't go bust:
'In 1975, SunTour introduced the Cyclone derailleur, which was a lighter, polished version of the SunTour V. SunTour's policy was to add a markup to production cost to set a "fair" price. They did not charge what the traffic would bear. In 1975, a Cyclone cost $16.00, a Campagnolo Nuovo Record or a Huret Jubilee cost $40.00 and a Shimano Crane cost $20.00. The Nuovo Record and Crane both weighed about 200 grams and the Jubilee weighed 140 grams. The Cyclone weighed 175 grams and it shifted best.
The result of SunTour's pricing policy was that their top derailleurs were specified for medium-priced bicycles, while their competitor's top derailleurs were found on top-of-the-line bicycles. With 20-20 hindsight, SunTour should have charged more for their top lines and invested more on research and development. SunTour never had more than twenty people working on research and development and this was simply not enough to design and develop and test new products for the 1980s marketplace.'*
