Manufactured by the famous company Terrot, this racing bicycle has an odd-shaped transmission. The chain is not the typical “Galle”, but has “positive” grafts that insert into their negative positions on pinion and chain ring. This system patented by Terrot lowers the friction compared to the standard ones; it’s also quieter, wears more slowly and helps to not waste energy. Despite the validity of this innovation it wasn’t fitted on other bikes, probably for the high production cost. This bicycle price was 425 Francs.
