Despite its dominance in the mid-1980s SR (Sakae Ringyo), has left only a faint historical footprint. It looks like the firm began in the mid-1960s. As Japanese bikes began to dominate the American consumer market in the 1970s, it seemed that most of the bikes were SR crank-equipped. The firm earned it business. From the least expensive to the top-of-the-line, SR cranks were well-made.

Hammered by Shimano's market dominance, the once powerful SR was acquired by Mori industries in 1987. The next year, the new SR purchased another formerly mighty Japanese component maker, SunTour. The resulting firm was renamed SR-SunTour.

In 1994, faced by ever-declining sales, Mori contemplated closing the firm. Instead, it was purchased by management and now SR and SunTour parts are made in Taiwan.

SR Custom 170mm crankset with 42-52 rings. Used, $75.00

  • This crankset uses 144 BCD (traditonal Campangolo diameter) rings.
  • It is designed to be mounted to a 122.5mm spindle with a JIS taper (as opposed to the ISO taper which works on Campagnolo, Nervar & T.A.).
  • SR made a number of different cranksets in the 1980s named "Custom". This is one of the nicest.

SR Silstar Motobecane 170mm crankset, 42-53 rings. Used, $50.00

SR produced the Silstar crankset for a long time, make small changes every few years. We believe this version, made for French bicycle maker Motobecane, was produced sometime in the late 1970s or early 1980s.
