General Information
As a part of a all-white city-bike-group from 85 with Simplex, Clb, Nervar and Lyotard, this illustrates the sad end of the formerly glorious French component industry. This derailleur was available in metal (standard), grey, white and black according to the catalogue from 1989. The clamp size was indicated with 28 - 28.6 mm. The black model that I found is exactly the same except for color and that the inner plate was additionally marked with the model type SXA 32. Regarding quality and design I agree, the construction of sheet metal and overall design and quality is poor.
