Stronglight is a French company specializing in the design and manufacture of high-end bicycle components.
The origins of Stronglight go back to 1906 when Achille Haubtmann founded in La Digonnière near Saint Etienne in France the Haubtmann establishments specializing in the manufacture of cranksets and pedals. The company quickly diversified by offering headsets, chainrings, cranks and crank axles.
At the same time, the Vérot-Perrin establishments competing with Ets Haubtmann installed at La Fabrique in France design and manufacture steel cranksets under the Strong brand. Louis Vérot after numerous tests developed a Dural aluminum crankset which was tested and validated in competition in 1931, it would be marketed under the Stronglight model 49 brand. In 1935, Jean Aerts became world champion with this new crankset. In order to diversify The Ets Vérot-Perrin also offer crank axles, chainrings and headsets.
In the 1970s, a period of mergers and acquisitions of cycle equipment manufacturers appeared, it was at this time that Ets Haubtmann acquired Ets Vérot-Perrin. Subsequently, the Thun company specializing in the design and manufacture of cranksets (largest manufacturer in Europe) takes 25% of the capital of Ets Haubtmann in exchange for the use of a patent for cold upsetting of the cranks which makes it possible to reduce significantly the costs. At the beginning of the 1970s, the Haubtmann establishments also created a design office of 5 engineers.
At the beginning of the 90s, Haubtmann Stronglight was faced with strong competition due to globalization, in 1993 the company was placed in bankrut.
A new company was created under the name of Stronglight, it took over all the industrial ressources of the Haubtmann Stronglight company, and was then bought in 1997 by Ircos (previously Sram France, Maillard, Sachs, Huret). This merger allows Stronglight to offer hubs and derailleurs.
In 2001, Stronglight was bought by the Zefal group following the bankrut of Ircos. Zefal decides to stop manufacturing Stronglight derailleurs and hubs.
In 2003, Stronglight bought the company Hurrycat, which specializes in the design and manufacture of very high-end, high-performance forks and seat posts.
In 2009, the Zefal group was in difficulty and chose to separate from Stronglight which was taken over by Joël Glotin (former manager of Zefal).
In 2015, Stronglight is placed in bankrut but a continuation plan allows the company to continue writing its history.
