Idéal is the brand of Les Établissements Claudius Jacquemard, based, almost inevitably, in St-Étienne, France. The company was founded in 1906 and specialised in the manufacture of hubs, freewheels and integrated cassette hubs with built in freewheels. In the tradition of Shimano and SunTour, this led Idéal to dabble in the manufacture of derailleurs.

I am aware of two Idéal derailleurs that made it into production. They are:

  • A 1931 three speed model that involved the guide pulley sliding along two angled rails (see French patent # 723,162). The angle of these rails means that the derailleur maintains a fairly constant chain gap, and as such, mirrors some of the features of SunTour’s slant parallelogram design.
  • A similar, but slightly different, two speed model that may also date from 1931, but was definitely in existence in 1935.

I do not know what became of the company, but I have seen adverts that indicate that a company called Établissements Jacquemard of St-Étienne was selling venetian blinds under the Ideal brand during the 1950s.
