The Tour de France has existed for over 100 years. It is the most famous cycle race in the world, without exception, covering over 2,200 miles over 23 days. Well it takes place mainly in France, the route often passes through neighboring countries. This is a test of stamina, skill and bicycles technologically most advanced ever designed. The motorcycle used in the Tour de France bicycle racing are specially designed to meet multiple demands cyclists must make during a race. The requirements of a bicycle race is defined by the International Cycling Union (UCI), the Association of Cycling, which oversees all competitive cycling events worldwide.

Racing bicycles are designed to do one thing: going fast. For this purpose, two features significant of these bikes. First, is the light, which means that the pilot should put less effort into promoting the bicycle, and two, makeup is the most streamlined as possible, up to and including the position taken by the rider. It is the combination of these two attributes that allows the rider to race to reach the speeds that make by the amount of time required.

Each component of a racing bike is designed to weigh as little as possible. The tires, for example, are usually aluminum alloy, a very light material. In addition, some bikes have carbon fiber wheels, which weigh much less. Most of the tires of this type have a triangular section, which allows for greater aerodynamic efficiency. To further reduce weight and increase aerodynamic wheel bikes are few rays as possible. Some tires rays with high-end sheet sections, which further reduces wind resistance. The motorcycle racing tires are light, narrow and smooth, thin tread. They are inflated to very high pressure, which increases the potential speed of the bicycle.

The term "groupset" means that the mechanical components of a bicycle race, which exclude the frame, fork, wheels, bars, stems, pedals, saddle and seatpost. Change is an essential part of any groupset. These devices consist of a chain, multiple sprockets (gears), and a mechanism that moves the chain from one sprocket to another. This system is what allows the pilot to adjust your speed and effort depending on the terrain. The transfer mechanism can be found in the stem of the bicycle, the handlebars or framework, but systems to fully integrate the use of the brakes and shift levers that allow the combination of driver changing gears without moving his hand. Derailed and were developed in the 19th century and beyond the introduction of full integration, which have changed little since.

There are a number of different manufacturers produce groupset complete bicycle, including Shimano, Campagnolo and Mavic, although the first two are probably the best known. Different companies have different philosophies, concepts, and cyclists are usually loyal to one brand over all others. As for not groupset components, mechanical components of a race bike should weigh as little as possible. Therefore, the carbon fiber has become popular in the manufacture of such items. They are used for levers, brake levers, cranks and parts derails.
