DISRAELI DOCUMENTS
As Huret is a French bike component manufacturer, you can expect some weirdness when it comes to model names. Here we have two derailleurs called 'Competition' and 'Route Leger'. I would call them 'Course Compétition' and 'Touriste Léger', respectively, but variety is the spice of life.
