Huret derailleur performance

[Drillium]

Does anyone know much about this 70's Huret derailleur please? Is it any good and how does it compare to Camp or others of the same era

No experience of that one, but maybe take a look here: https://www.disraeligears.co.uk/site/huret_derailleurs.html

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.

Looks like a Svelto, cheap and cheerful and graced many a Carlton and Raleigh. Worked OK until someone dropped the bike sideways on it lol

Spawned the lightest mech of the era and beloved of TT bods.

Are they quite easy to come by in good condition still?

Yes, they’re pretty common, so not hard to get on eBay for a decent price.
