About Ebykr
Ebykr celebrates classic and vintage lightweight bicycles through provoking imagery and opinion. Let's roll together!
The storied history of Cycles Mercier spans well over a century now, marked by rapid industrialization, a long-running racing dynasty, pioneering technical innovations (like the Méca Dural frame), and dramatic corporate collapses and revivals (note the use of plurals here).
From its humble beginnings in the manufacturing cradle of Saint-Étienne, the marque became synonymous with the “Purple Army’ of the peloton, propelling legends like Raymond Poulidor—France’s beloved “Eternal Second”—to eternal fame against rivals like Anquetil and then Merckx. Beyond the racecourse, Mercier displayed remarkable technical audacity. Their mass-produced Méca Dural frames utilized aviation-grade duralumin and mechanical assembly methods that predated the modern aluminum “fat tube” era by several decades.
Yet, this legacy has been fragile. Following a crushing bankruptcy in 1985, the brand navigated a labyrinth of ownership changes—from France-Loire to the Accell Group—before seeing new life in the 21st century through both family-led apparel ventures and ambitious industrial manufacturing reboots in the Ardennes.
Here is a chronological timeline of major corporate events at Cycles Mercier, spanning from 1919 to the modern era, based on the sources used for an accompanying Ebykr article on its remarkable history:
| Event Date(s) | Event Type | Event Description |
