Hinault's steel frames were made by his mechanic, Alain Descroix. On page 16 of Ciclismo su Strada, it shows a picture of Decroix welding a frame and subsequent pictures show him finishing th frame and setting it up for Hinault. Hinalut 's book states he left Renault in 1983 and his mechanic Alain Descroix went with him to La Vie Claire. Descroix was Hinault's mechanic for six years.
