Ofmega Mistral ‘Maillot Jaune’

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 fancy Italian type of orange sorbet.

This particular Mistral has an adjustable cable outer stop, 42mm long parallelogram arms (note the small space between the adjustment screws), an aluminium hanger bolt and sprung pivot cover and weighs 171g. This is my lightest Mistral.

The slightly alarming colour is supposedly a homage to the Maillot Jaune (yellow jersey) worn by the leader of the Tour de France.
