Sunrace was formed in 1972 in Taipei City, Taiwan, just as the Taiwan cycling industry was taking off. Mr. Tony Hsu saw an opportunity for producing derailleurs in Taiwan, since at that time there were no domestically made derailleurs and the import of derailleurs were very limited in supply. Initially they sold friction 10 and 12 speed derailleur sets to local Taiwan cycle manufacturers. After over 20 years of producing high quality cycle components they were involved in a joint research and development project between Sunrace and Taiwan Government (Largest Research Centre in Taiwan with over 6,000 in staff and 1,000 PHDs). Since then they have numerous patents and began producing high-end completion level components after working with the Santa Cruz race team. If you want quality products at a low price, you know where to look.
