Sorry, I got nothing. I know that around the mid to late '80s Modolo was working with Mavic. Mavic used rebadged Modolo brakes to complete some of their gruppos, as they didn't make brake calipers. I'd guess that the deal worked both ways and Mavic could have supplied all the other components to Modolo to make up a gruppo. Just a guess...how about some pics of this stuff?
