In 1969, SunTour was the first Japanese gear and shifter manufacturer to introduce indexed shifting on bicycles (indexed shifting appeared at least as early as the Funiculo derailleur fitted to 1935 Schulz bicycles). Although their system, called "Five-Speed Click", worked well, it proved an idea ahead of its time and did not catch on with the riding public. Another design innovation was the first practical Japanese freehub — the "Unit-Hub" - which combined freewheel and hub in one component (unit hubs were available at least as early as the 1938 Bayliss-Wiley, probably earlier). The freehub greatly increased the strength of the rear wheel, but the idea was not pursued.
