As promised...The "final word" from SR Suntour itself....
Thank you for your inquiry.
Sorry, our office does not have any information regarding SR, Suntour, or SR
Suntour products prior to 1998.
Sakae Ringyo has been a well recognized component parts manufacturer in
Japan from 1950's through 1985.
They changed their name to SR Suntour after 1985 take over of the Suntour
We are aware that some frames were built for Sakae Ringyo and offered in
their catalog as late as 1988.
These were listed as "Litage" model.
Made with 5056 aluminum tubing and aluminum AC4C Accurad lugs.
These were thermal bonded together.
As far as we know, SR did not offer fully equipped bicycles.
(Does not look good for component suppliers to compete with the major
bicycle brands they are selling parts to.)
And the frames were not available after the factory moved from Japan to
We did "hear" about some nice road frames made in California during the late
1980's with SR name.
We do not have any data on that.
