[4] Caput stopped racing in 1957 and went into the real estate business in Vincennes, an eastern suburb of Paris.

The French businessman, Jean de Gribaldy, took over sponsorship the following year with Frimatic, another maker of washing machines, as main backer.

The following year Antonin Magne retired from running the Mercier team, which had lost BP as secondary sponsor.

An incidental effect of Caput's arrival as manager is that Raymond Poulidor and the other riders were allowed zips at the necks of their jerseys, something Magne had always thought unhealthy.

Louis Caput died in Paris on the first day of 1985 and is buried at Ivry Cemetery, Ivry-sur-Seine.
