This second JC model in this collection is an Argentinian copy of a late 1970s Huret Eco. Even though JC started with a design that is the very definition of banal normality, they couldn't resist the temptation to add their signature touches of lunacy:
- The b-pivot bolt has a screwdriver head - which is never a good idea .
- The adjustment screws have huge, 7mm, extravagantly domed heads. Cool!
- The cable is clamped with an 11mm nut - what are they expecting? The kind of hauser you use to 'make fast' a super-tanker?
- In contrast, the pulleys are charmingly petite 9 toothed items without dust covers.
It is always a pleasure when something, so comprehensively, lives down to expectations.
One, more sensible, feature of this derailleur is that it is designed to fit a Campagnolo (not a Huret) dropout.
As with all the JC derailleurs in this collection I have no real idea of the date of this product. I just made my best guess. This one is so shiny that it could have been made yesterday - and I wouldn't rule that out.
