The Sachs-Huret Super Success was a Huret Super Success with a new logo. It retained the amazing titanium knuckles and devatatingly low weight.

It also retains a number of features that are a little incongruous on a high-end derailleur in 1982. It still has the second threaded hole in the lower knuckle, to use if you want the capacity to handle a 28 tooth cog. It also has Huret’s adjustable ball bearing pulley wheels, with a toothless idler pulley - as found on an early 1960’s Huret Allvit.

This example of the Sachs-Huret Super Success displays these features (amongst many others):

• The logo on the outer parallelogram plate is black paint on a grey background.
• There is a 'T' in a circle on the b-knuckle. 'T' is possibly for 'Titanium'.
• The spring on the cable adjuster and the b-pivot adjuster plate are black steel.
• The, black, steel, 6mm Allen key b-pivot bolt locks into the dropout using a cunning 4mm Allen key expander screw. But it also has a conventional locknut. Odd.
