SunRace was originally the brand of a company called Roots Enterprise, then the company became SunRace Roots Enterprise (or possibly sometimes Sun Race Roots Enterprises) and then Sun Race Sturmey-Archer (or possibly sometimes SunRace Sturmey-Archer). This application indicates that in 1994, during the middle period, it used the brand S.R. Roots. That must have gone down well with SR SUNTOUR.
