In which decade did practical and reliable multi-speed derailleur systems begin appearing consistently on racing bicycles?
Answer
The 1930s
Although the chain drive made gearing possible earlier, the first practical, reliable derailleur systems for multiple ratios matured and began appearing consistently on racing bicycles, notably in the Tour de France, during the 1930s.
