Suntour could trace its origins to 1912, when the then-named Maeda Iron Works began making bicycle sprockets and then freewheels.

Suntour's business really took off with its introduction of the slant parallelogram rear derailleur in 1964. This innovation, upon which all modern derailleurs are based, allowed the derailleur to maintain a constant distance from the sprockets and vastly improved shifting.

Suntour thrived and expanded, eventually producing complete groups, all well-designed and beautifully made. But upon the expiration of Suntour's slant-parallelogram derailleur patent, arch-competitor Shimano, adopting this design, became a relentless and dominating force in bicycle components, crushing the weaker Suntour company.

In 1988, the now-struggling Suntour company was purchased by the a Taiwan firm and by 1993, once-dominant Suntour owned only five percent of the U.S. market.

SunTour GPX Aero Brakeset. New, $300.00/set
