General Information

Suntour Sprint became Sprint 9000 in 1987 and received a re-designed parallelogram and cage, along with index ability for 6 and 7 speed Suntour Accushift Winner Pro freewheels.  Supposedly, later models include support for 8-speed Accushift freewheels

Suntour introduced the Sprint gruppo, price between Superbe Pro and Cyclone, to compete with Shimano 600 Ultegra. Suntour Sprint was splendid value, everything looked expensive and the finish was superbe.

Nobuo Ozaki, the head of product development at Maeda, invented the slant parallelogram rear derailleur in 1964 and Maeda obtained worldwide patents on the design. For the next 20 years, Suntour produced technically superior derailleurs. Suntour's slant parallelogram broke the image of Japanese components as being cheap copies of European components.

Sources report that this derailleur can handle no more than about a 23T when used with indexing, but at least a 26 in friction mode.  Who knows what you may be able to coax out of it though.

SunTour (Maeda)

SunTour derailleurs have a two-letter date code. On rear derailleurs the code is stamped on the back side of the inner parallel arm. On front derailleurs it is stamped on the back side of the inner cage.

The first letter represents the year. Larry Osborn and I believe O (Oh) is 1972, V is 1979 and A is 1984. As with Shimano, the second letter is the month code, where A is January and L is December.

The earliest Suntour derailleur I have found with a code is marked OF. A rear derailleur marked OD (corresponding to April of 72) was reported by Leighton Walter. I have a bike that dates from between 1970 to 1972 that has the original SunTour derailleurs. These derailleurs do not have date codes on them, so I believe the coding started sometime between 1970 and April of 1972.
