During the 1980s and 1990s, EDCO, a Swiss company that made beautiful Swiss products with precision Swiss bearings - bottom brackets, headsets, hubs, all that good stuff - decided that it wanted to offer complete groupsets.

Its chosen approach was to buy in components like brakes and derailleurs. EDCO sold its high-end Swiss bicycle jewellery at high-end Swiss prices - so, coming from French-speaking Switzerland, it was looking for the very best derailleurs that the Francophone world could provide.

My knowledge is a touch sketchy, but I am aware of six generations of these EDCO derailleurs:

  • The first EDCO derailleur that I remember, possibly from 1984, was a rebranded Simplex SLJ6600 T. This was, arguably, the top of Simplex's range at the time.
  • Then, possibly in 1985, I think they used a rebranded Simplex SLJ5500 T. This was arguably a step down from the SLJ6600 T, but was marginally lighter, and possibly more 'racy'. Or they may have made the change because Simplex was in some chaos at the time.
  • In 1986? they dropped Simplex and adopted a rebranded version of Sachs-Huret's top-of-the range New Success (47.1D). This had a cleaner, more modern, look that fitted better with the EDCO aesthetic. At the time Sachs-Huret also made a lot of noise about how they were determined to build a top-quality technically advanced brand. Finally, I think that EDCO may also have offered a version of the long cage Sachs-Huret New Success Touring (47.1T).
  • In 1988? EDCO moved into the world of indexing with a rebranded Sachs-Huret New Success ARIS (47.2D). The EDCO version of this derailleur had something of a cult following, because it was anodised silver, rather than the grey colour of the Sachs-Huret original. Again, I think that EDCO may also have offered a version of the long cage Sachs-Huret New Success ARIS Touring (47.2T).
  • For 1990? EDCO moved up to the 8-speed Sachs-Huret New Success Sport (54.01D). I don't know if EDCO offered a long cage version.
  • And finally in 1994? moved on to the Sachs New Success Sport (RNS 00). This was offered in a choice of 'looks' - silver anodised for the 'racing' groupset and with a black & red outer parallelogram plate for the 'triathlon' groupset. EDCO additionally offered the long cage Sachs New Success MTB (MNS 00) derailleur both as part of a touring groupset and also as part of a mountain bike groupset.
  • ...

And there is probably more that I have forgotten (or never even knew) about.


This is a beautiful, unused, example of the third generation described above. It is a rebranded Sachs-Huret New Success (47.1D).

Some distinguishing features include:

  • It is all silver.
  • It is the short pulley cage version. This has shorter parallelogram plates (40mm) than the ‘touring’ version (which has 47mm plates).
  • The inner parallelogram plate is aluminium and has a oval depression in its centre.
  • The cable clamp bolt takes a 6mm Allen key.
  • The adjustment screws are labelled 'L' and 'H'.
  • The inner pulley cage incorporates a spoke protector at the tension pulley.
