S.R. ®
A slippery abbreviation, with two different meanings:

* As a trade name, it is an alternate form of Sakae Ringyo, a major Japanese maker of aluminum parts, particularly cranks and seat posts. In the 1990's, S. R. bought what was left of the bankrupt Sun Tour, and the combined companies are now known as SR-Sun Tour.

* The abbreviation "S.R." is also commonly used in want ads for older racing bicycles, where it refers to the old top-of-the-line Campagnolo Super Record gruppo.
