Sugino is a Japanese manufacturer of road and track bicycle components, founded in Nara, Japan, in 1910. It made a variety of cycling components, including cranksets and chainrings. After flagging in popularity due to Shimano's increased dominance of the Japanese bicycle component industry in the 90s, the company has recently become more prominent, due to the rising popularity of fixed-gear bicycles and the cache associated with the "Sugino 75" track racing equipment.
