What is "suntour"

SunTour® (Maeda) was the most important Japanese manufacturer of bicycle components based in Osaka until 1988, when Sakae Ringyo Company (abbreviated S.R.), a major Japanese maker of aluminum parts, particularly cranks and seat posts, bought what was left of the bankrupt SunTour, and the combined companies are now known as SR-SunTour. SunTour reached a zenith of sales and commercial success from the late 1970s to the mid-1980s. Its products range from suspension forks to derailleurs.
