Simplex Prestige Cadet (1st style)

Simplex Prestige Cadet derailleur (1st style) main image

To celebrate their 1962 move from steel to modern space-age plastic technology Simplex launched a range that perversely included this living fossil. The Prestige Cadet is a single pulley derailleur - for those stick-in-the-muds who still dreaded the extra ‘drag’ caused by a second pulley wheel.

One pulley gave less drag, less weight - but no capacity and, more importantly, a gear change so imprecise as to be worse than useless.

This version has the early ‘thumb-wheel’ adjusters.
