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 late example of the Huret Super Success. Some of its features are:

• 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.

Finally this example retains its much loathed ‘useless plastic part’ that plugs into the b-knuckle. This object could only be removed by taking the wheel off the bike and pushing it out through the hollow allen bolt. Even then it often broke, causing the poor bicycle shop mechanic to receive a torrent of abuse from the customer for spoiling the look of their bike. God, I hated that useless piece of crap!
