Sachs-Huret New Success (47.1D 1st style)

Sachs-Huret New Success derailleur main image

Despite being the spitting image of the 1973 Shimano Crane, the 1985 Sachs-Huret New Success was a huge step forward from its Huret antecedants. Crucially, for Sachs-Huret’s new flagship derailleur, it sported lots of aluminium, only the rear parallelogram plate was a pressing, the other parts were castings, it had a dropped parallelogram (although without any slant). And, finally, real care and attention had been paid to finish, with silky anodising and well chromed small parts.

It was a demonstration by Sachs that they were no longer interested in the ‘French tradition’ of (mostly odd) derailleur design, and were determined to compete with the best in the world - the Japanese.

A good effort - but it is hard to catch up a couple of decades in a single bound.

As with any derailleur bearing the Huret name there are a bewildering number of tiny and meaningless variations of this basic design.

This example displays the following features:

  • 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 4mm Allen key.
  • The adjustment screws are NOT labelled 'L' and 'H'.
  • The inner pulley cage does not have a spoke protector at the tension pulley.
