Suntour New Winner Freewheel - Versatility is the biggest feature, versatility which lets you build custom five, six or seven speed freewheels with ranges of 12 to 32 teeth, all on the same fully serviceable freewheel body.
Like all Suntour freewheel bodies (except the all alloy MicroLite), the New Winner is made from heat treated CrMo steel. It features full adjustability to make the toughest, most reliable freewheel body on the market.
As a seven speed freewheel, the New Winner body is assembled with 2.7mm to 3.2mm spacing, as in the Ultra six mode, an additional sprocket, which can be as small as twelve teeth, is screwed into the outermost sprocket. This mode provides seven gears within the 126mm dimensions of a standard six speed hub. The U-6 chain must be used - range is 12 to 32T.
7 Speed Assembly:-
Sprocket Codes (smallest to largest sprocket):- U - L - T/P - R - R - A - A
Spacing (smallest to largest sprocket):- 3.2mm - 3.3mm - 2.9mm - 2.9mm - 2.7mm - 2.7mm |

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.
