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, rather battered, early 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 NO 'T' in a circle on the b-knuckle.
• The spring on the cable adjuster and the b-pivot adjuster plate are titanium coloured steel.
• The, titanium coloured, steel, 6mm Allen key b-pivot bolt locks onto the dropout with a conventional lock nut.

Note that this example has its p-pivot bolt screwed into the '28T' hole - which is unusual for a Super Success.
