It's not thought thatb the Ganolo sellers, Cycles Laurent/Europe Cycles had their own in-house frame-builder. The firm is thought to have used Edmond Polchlopek instead who had a workshop in the eastern suburbs of Paris (see Cycles Polchlopek), although when the former top amateur roadman opened his first shop in the Paris suburb of Pontault -Combault in 1975 he was known to have engaged the well-known jobbing builders BACO from Romainville to build his shop's frames. This Laurent Ganolo bears little resemblance to a BACO-produced frame, and it seems reasonable to ascribe it to Edmond.
This design is for all intents and purposes a simpler form of his Rigideole II, which used a more complicated and robust seat tube configuration.
