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 Royal 10 cm x 26.0mm bar diameter. New, $60.00

Part# 31108

  • We date this stem to the mid-1970s. The design of the SR Royal stem evolved over the years, but we believe this is the original design. It is very much like a Cinelli 1A.
  • Quill diameter: 22.2
  • Weight: 310 grams

Though new, the stem does have a small scratch on the top. See second picture.

And the other side. Most of the scuffing is below the quill insertion limit line, so it will not show.


SR high-rise 6cm quill stem for 25.4mm diameter handlebar. Used, $35.00

This stem has an extra-long 135mm quill.

We measure this stem thus:

  • 60mm horizontal extension, center-to-center
  • 135mm vertical rise from the minimum insertion mark to the center of the handlebar.
  • The stem angle is -6 degrees.
