Where to look for these sold out chainrings: Note: The splined chainrings above are Suntour freewheel cogs.  Suntour is out of business and the cogs are no being made.  These cogs were used in the 'A' position on the following freewheels: Winner, New Winner, Winner Pro, Perfect, Ultra, Pro Compe.  There may have been others. These are the ones I'm sure about. The 'A' position is that of the two largest cogs on the freewheel. I haven't found many sources for individual cogs, but there are several sites on the web selling freewheels. Search on 'Suntour freewheel' to find them. For some excellent photos and drawings of the freewheels see YellowJersey The threaded chainrings are Normandy-Mailard or Sachs-Mailard cogs.  They are the 'MR' or 'GY' position. The only site I found was http://the-bici.com

BD spacer for Mountain Tamer QuadPlus $2.00
Wave spring for Mountain Tamer Triple or Mountain Tamer Quad Plus  $2.50
Retainer for Mountain Tamer Triple or Mountain Tamer Quad Plus  $1.50

The wave spring applies the proper force to always ensure a tight fit         of  the chainrings allowing for tolerance variation.         The retainer holds the chainrings securely and will not come off even             in the most adverse conditions, yet can be easily removed with a                 small screwdriver or blade. Included with the adapters
