1990 Koga Miyata Ridgerunner Alloy

In the late 80's and early 90's, bike companies were pushing the boundaries and challenging the preconceived notion that a mountain bike had to be built in the classic double diamond shape. The Japanese manufacturer, Koga-Miyata was among the companies challenging the norm. Other brands experimented with elevated chainstays but the unsupported bottom bracket created an incredibly flexible frame. Koga-Miyata approached the problem with a sizable gusset welded from the bottom bracket to the down tube. This gusset made the Ridgerunner Alloy one of the sturdiest alloy elevated chainstay designs.
