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 a sex toy.
This particular Mistral has an adjustable cable outer stop, 52mm long parallelogram arms (note the large space between the adjustment screws) , a steel hanger bolt and sprung pivot cover and weighs 195g. 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 pink colour is fantastically cool in a Barbie kind of way, but is supposedly a homage to the Maglia Rosa (pink jersey) worn by the leader of the Giro D’Italia.
