History of the road bike :

The road or racing bike appeared in 1884 with the first bikes whose front and rear wheels were of equal diameter and whose traction was by chain. The vertical position of the cyclist was comparable to that of current cyclists. At the end of the 19th century, cycling races multiplied, they made it possible to make this sport popular and to professionalize it. Cyclists are sponsored by big brands.

At the end of the 19th century, road cycling was practiced on paths or tracks, then at the beginning of the 20th century with the development of the automotive, roads were created. At that time, the chain drivetrain sprocket was fixed with the rear wheel of the road bike, then the freewheel was designed, it made it possible to travel longer distances because it is now possible to benefit from the inertia of the road bike , when launched to save energy. Then comes the invention of the rear derailleur which further improves performance by using a development ratio adapted to the profile of the road, road cycling was born. The front derailleur was designd in the middle of the 20th century, the tubulars were glued to the aluminum rims which replaced the wooden models. the number of speeds will gradually increase thanks to the invention of the cassette by Simplex until reaching 12 speeds today. The shifters attached to the frame are replaced by indexed shifters fixed on the handlebar. The frame of a road bike has long been in steel, then in aluminum or titanium and since a few years in carbon for weight gain, comfort and rigidity.
