Huret Svelto (2000 1965 version 2nd style)

After the rampant complexity of their 1958 Allvit, Huret went all out for simplicity with the 1963 Huret Svelto. It was a pared-down, all-steel economy model that was cheap to manufacture, sold in millions and had any number of imitators.

It worked OK when new, but the parallelogram lacked the torsional rigidity of more three dimensional designs, and the pivots quickly loosened destroying any pretense at precision - not so much of a problem when your main competition is the 1962 Simplex Prestige - but a serious short coming when you are up against a 1967 Shimano Skylark.

Nick Wells, a correspondent of mine who admits to a youthful yearning to ‘marry that nice blonde lady from The Champions’, writes:

“My first 'real' bike was a heavy steel 'racer' from Grattons mail order catalogue. There were only two bikes in it, one was a Raleigh, which I think had Simplex gears, and the cheaper unbranded one that I had, which had a Huret Svelto set-up.

I loved that bike, and went miles on it, and, although after a few years my chainset used to clank a little, the gears never let me down. My brother had a Carlton (with Reynolds 531 tubing) which was much lighter than mine, and it had Campagnolo Gran Sport gears, which I envied immensely. He himself though, always craved a set of Campag Record gears, so I guess neither of us was fully satisfied!”

For me the Huret Svelto is as much a part of the late 1960’s and early 1970’s as men walking on the moon, the three day week, Frank Zappa’s Hot Rats and Lord Anthony snorkel parkas with rabbit fur around the hood. Was it all a strange dream?

There is a vast and bewildering range of different variants of the Huret Svelto. Over its 13 year life it enjoyed:

  • At least 4 different designs of b-knuckle.
  • At least 3 different designs of p-knuckle, changed at different times from the b-knuckles.
  • At least 4 different designs of parallelogram plates, changed at different times from the knuckles.
  • At least 5 different designs of pulley cage plates, changed at ....
  • At least 7 different guide pulleys and at least 7 different tension pulleys and untold numbers of combinations of these, all changed at ...
  • And so on...

Understanding all this complexity is made even more difficult because Huret does not, necessarily, use up-to-date images in its catalogues. So, for example, a 1975 catalogue may, or may not, depict the exact style of Svelto on offer in that year.

it reminds me of a conversation that I had with an engineer working in the bicycle industry in the mid 1980s. I was waxing lyrical about Toyota's Total Quality policy (religion?) of 'continuous improvement'. He (inevitably it was a he) was unimpressed.

He suggested that Toyota had excellent teams of design engineers producing excellent initial designs. These engineers were given time and resources to thoroughly challenge and develope their designs. These developed designs were then rigorously tested using formal and extensive test protocols. Finally, when the product hit production, the icing on the cake was the policy of 'continuous improvement'.

In his opinion, in the European bicycle industry, a single engineer, working alone, often initially produced a mediocre design. Virtually no attempt was made to challenge or develope this design. It was then subjected to a minimal amount of informal testing, much of it riding around the factory car park. Finally, when the product hit production, it enjoyed an endless series of desperate and slightly aimless 'improvements' in a hopeless attempt to solve fundamental problems. Both icing and cake were largely absent.

I am genuinely uncertain whether all the changes to the Svelto were desirable 'continuous improvement' or were worryingly 'desperate and slightly aimless'.


I think that this example is one of the second, 1965, versions of the Huret Svelto, with a slightly redesigned b-knuckle. In this case it is the option with a cable adjuster. Some key features may be:

  • The horizontal part of the b-knuckle has a curved shape.
  • The front of the vertical part of the b-knuckle has a squarish shape.
  • It has a silver Huret style hanger with nothing stamped on it.
  • The logo on the top parallelogram plate is stylised 'Svelto' and the word 'PATENTED' with no background.
  • The logo on the bottom parallelogram plate is 'HURET MADE IN FRANCE'.
  • The p-knuckle is about 23mm wide - perhaps indicating that it can be used with 5-speed freewheels.
  • The pulley cage plates are the first style of plates used on Sveltos with a riveted on, three position, ‘trap’ for the pulley cage spring..
  • The pulley wheels are black, round, have ball bearing races and are plain steel.
  • It has a cable adjuster.
  • The adjustment screws have slotted heads.

One odd feature of this particular derailleur is that the cable clamp washer has a large 'flange'. This may not be original as derailleurs from Sveltos before 1968 usually have a small 'peg'.
