The bicycle above which does not bear any markings (re-enamelled?), is built on a Jacques Busset frame, with a VITUS Duralinox fork. Both the stem and seat post were internal expander type fixings. The chrome details are stunning.
The stem was handmade, in a similar style to Alex Singer of Paris. There was a great deal of friendly rivalry among constructeurs in this period and a lot of novel innovation because of it

CIM MARCADIER
C.I.M.
André Marcadier was a touring cyclist and an exceptional welder who brazed steel frames seamlessly, with virtually no brazing thickness, and, according to witnesses, without using a file.
In the early years, starting in 1948, in partnership with Mr. Joannès Imbert, he manufactured frames and assembled bicycles under the C.I.M. brand.
Touring cyclists used tires with sufficient cross-sections to ensure adequate comfort for long distances. To limit the weight at the periphery of the wheels, the rims became increasingly narrow. It was therefore difficult to ensure that the brake pads spread sufficiently to be able to remove or reinstall the wheel with an inflated tire.
André Marcadier had solved the problem with brakes whose pads were movable. The pads could be positioned vertically. This way, the tires were inflated when the wheel was removed and reassembled. They were returned by springs and it was not even necessary to lower them before getting on the bicycle. They instantly returned to the correct position as soon as the levers were touched, before coming into contact with the rim. A drawing of these brakes was published on 16-10-1948 in the magazine Le Cycle.
