the 80s was the death of the freewheel cog board , as the distribution costs were making it hard to pull off any more

I think Sachs Malliard was the last to offer a build by selecting cogs freewheel,

and SRAM threw the Malliard division over the transom when they bought out the Fichtel-Sachs group

Regina used to have LH thread cogs on the back side of the body and RH thread for the rest,


others mixed spline and screw cogs .. usually the plan was exclusivity each brand was incompatible with its competitors.

as FB says A French company may have several brands , an Italian one another ..

Sun tour had th winner and the winner pro and the perfect line ... little interchangeability ..
