The Mistral has its enthusiastic fans - who claim it is made of a ‘hi-tech polymer’ - not ‘plastic’ (like a despised Simplex). It is a genuine, high quality, precision, cycling product, not merely one of Darth Vader’s minor internal organs.

This particular Mistral has an adjustable cable outer stop, 52mm long parallelogram arms (note the large space between the adjustment screws), an aluminium hanger bolt and sprung pivot cover and weighs 177g. Perhaps the longer parallelogram arms give the capacity to take a bigger cog and to cover a freewheel with more cogs, but I have not been able to find any reference to an alternative spec.

The black Mistral was less glamourous than the other colours - but it was the colour that retained its youthful looks even after being pelted with corrosive oily slime - and it sold surprisingly well.

Genuinely stylish.
