The Huret Super Success was a Huret Success with drilled pulley cage plates and a silver/grey look. It was (only just) even lighter than the Huret Success. The gear change remained at least as good (or not as bad) as Campagnolo’s Super Record.

It retains a number of features that are a little incongruous on what was, at the time, possibly the most technologically advanced derailleur in production. 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 is a mid-period example of the Huret Super Success. Some of its features are:

• The logo on the outer parallelogram plate is a metallic sticker with silver writing on a black 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.
