Cycles GANOLO is a French company based near Versailles, at St Germain-en-Laye, to the east of Paris. It is owned by the family of former Pro rider Maurice Archambaud. The GANOLO name was conjured up in the late 70s and early 80s in order to market the frames at a time when Italian brands such as COLNAGO, Pinarello, Guerciotti etc were attacking the French market and depriving French builders of sales.
The GANOLO brand was part of a larger wholesale company based in the same premises, called Europe Cycles.
The company also had and still have a large retail shop, CYCLES LAURENT in the centre of Paris, at 9 Boulevard Voltaire from which it sells Casati, Pinarello and a full range of other frames, including their own brand Cycles Laurent. The GANOLO name is no longer used.
No one is seems to know whether the company actually built its own frames, but there are strong reasons and arguments for thinking that Edmond Polchlopek built at least some of the frames.
