SR - Sakae Ringyo tandem cranksets

On this page: Apex 170mm right captain's crank arm | SR Sakae 170mm right captain's crank arm

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 Sakae 170mm tandem captain's right crank arm. Used, $25.00/each

This plain crank should go with whatever maker's cranksets are on your tandem.

It was nice of SR to stamp this arm right so that it is obviously a tandem arm.
