Lucien Juy
Lucien Charles Hippolyte Juy was a French industrialist who made derailleur gears. He is credited with making the first derailleur with a collapsible parallelogram. A hinged frame swung in and out from the frame and fed the chain to one of a number of sprockets attached to the hub. Juy's derailleurs, sold as Simplex derailleurs, were novel in having a jockey wheel to correct the tension of the chain as it moved across differently sized sprockets. History Lucien Juy owned a bicycle shop in Dijon, Côte d'Or, France. It was there that he made the first Simplex derailleur in 1928. The bicycle historian Hilary Stone said: "It used a single pulley to tension the chain and a pair of guide plates to push the chain to each one of two sprockets. The whole arm was spring-loaded in order to tension the chain – this was the first use of the sprung top pivot which was to become an essential part of the modern indexed derailleur as we know it today. The pulley and guide plates were moved side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derailleur Gears
Shimano 600 front derailleur (1980) A derailleur is a variable-ratio bicycle gearing system consisting of a chain, multiple sprockets of different sizes, and a mechanism to move the chain from one sprocket to another. Modern front and rear derailleurs typically consist of a moveable chain-guide that is operated remotely by a Bowden cable attached to a shifter mounted on the down tube, handlebar stem, or handlebar. When a rider operates the lever while pedalling, the change in cable tension moves the chain-guide from side to side, "derailing" the chain onto different sprockets. Etymology ''Dérailleur'' is a French word, derived from the derailment of a train from its tracks. Its first recorded use was 1930. History A modern road bicycle drivetrain with front and rear derailleurs Various derailleur systems were designed and built in the late 19th century. One example is the Protean two-speed derailleur available on the Whippet safety bicycle. The French bicycle to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The earliest archaeological finds within the city limits of Dijon date to the Neolithic period. Dijon later became a Roman settlement named ''Divio'', located on the road between Lyon and Paris. The province was home to the Dukes of Burgundy from the early 11th until the late 15th centuries, and Dijon became a place of tremendous wealth and power, one of the great European centres of art, learning, and science.

Many still-inhabited town-houses in the city's central district date from the 18th century and earlier. Dijon's architecture is distinguished by, among other things, '' toits bourguignons'' (Burgu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcyon
The Alcyon was a French bicycle, automobile and motorcycle manufacturer between 1903 and 1954. Origins Alcyon originated from about 1890 when Edmond Gentil started the manufacture of bicycles in Neuilly, Seine. In 1902, this was complemented by motorcycle production and in 1906, the first cars were shown at the fair "Mondial de l'Automobile" in Paris, France. Also in 1906 it founded the professional Alcyon cycling team which was active until 1955, including winning the Tour de France 6 times. Motorcycle racing In 1912 Alcyon competed at the Isle of Man TT races with a 348cc single-cylinder engine featuring two inlet valves and two exhaust valves. Both bikes failed to finish the Junior TT race. Alcyon had local success in France during the 1920s, with riders such as Marc Jolly, Marcel Mourrier, Jean Durand and Lucien Lemasson winning races. During this time too, this bicycle brand got its nickname "l'intrépide Alcyon". Voiturettes before the World War I Two models were sho ...

Paris–Roubaix
Paris–Roubaix is a one-day professional bicycle road race in northern France, starting north of Paris and finishing in Roubaix, at the border with Belgium. It is one of cycling's oldest races, and is one of the 'Monuments' or classics of the European calendar, and contributes points towards the UCI World Ranking. The most recent edition was held on 17 April 2022. Paris–Roubaix is famous for rough terrain and cobblestones, or pavé (setts),Paris–Roubaix is popularly known throughout the English-speaking world for its 'cobbled sectors', but this is a misnomer as the sectors are actually paved with granite setts, roughly hewn blocks, which are smoother and safer than true cobblestones (prominent rounded pebbles often used on inner city streets). This article maintains the misnomer 'Cobblestones' but attempts to clarify the misnomer where relevant. being, with the Tour of Flanders, E3 Harelbeke and Gent–Wevelgem, one of the cobbled classics.

Antonin Magne
Antonin Magne (; 15 February 1904 – 8 September 1983) was a French cyclist who won the Tour de France in 1931 and 1934. He raced as a professional from 1927 to 1939 and then became a team manager. The French rider and then journalist, Jean Bobet, described him in ''Sporting Cyclist'' as "a most uninterviewable character" and "a man who withdraws into a shell as soon as he meets a journalist." His taciturn character earned him the nickname of The Monk when he was racing. Professional cycling career Early career Magne became a professional cyclist in 1927. He was part of the Alleluia Team which, with Pierre Magne, Julien Moineau, Marius Gallotini, Arsène Alancourt, and André Cauet, won the 1927 GP Wolber, considered the unofficial world road race championship. Magne first rode the Tour in 1927, alongside André Leducq in the France team. 1931 Tour de France In 1931, defending champion André Leducq was not in good shape, so Magne took over the role as team leader.

Polyoxymethylene
Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. As with many other synthetic polymers, it is produced by different chemical firms with slightly different formulas and sold variously by such names as Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac and Hostaform. POM is characterized by its high strength, hardness and rigidity to −40 °C. POM is intrinsically opaque white because of its high crystalline composition but can be produced in a variety of colors. POM has a density of 1.410–1.420g/cm3. Typical applications for injection-molded POM include high-performance engineering components such as small gear wheels, eyeglass frames, ball bearings, ski bindings, fasteners, gun parts, knife handles, and lock systems. The material is widely used in the automotive and consumer electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
