The Tour de France has existed for over 100 years. This is the most famous bike race in the world, without exception, covering over 2,200 miles on the course of 23 days. Even if it takes place mainly in France, the route often passes through neighboring countries. This is a test of stamina, skill and some bicycles most technologically advanced ever made. The bicycles used in the Tour de France are in a race bike, and specially designed to face many demands of cyclists must make during a race. The requirements of a bicycle race is defined by the Union Cycliste Internationale (UCI), the Association of Cycling which oversees all the events of competitive cycling in the world.

Racing bicycles are designed for make a thing go fast. To this end, there are two important features of such bikes. One, which is lightweight, which means that the cyclist needs to less effort to stimulate the bike, and two, its composition is as aerodynamic as possible, up to and including the position taken by the runner. It is the combination of these two attributes allows riders to reach speeds that make the amount of time required.

All components of a road bike is designed to weigh as little as possible. Tires, for example, are usually aluminum alloy, very light material. Moreover, Some bikes have wheels carbon fiber, which weigh much less. Most tires such triangular cross sections, which allow greater aerodynamic efficiency. To further reduce weight and increase aerodynamic bicycle wheels have many spokes few races as possible. Some high-wheelers have end radii, with a weathervane articles, which further reduce wind resistance. The tires of racing bikes are lighter, have a narrow, smooth, thin tread. They are inflated to a very high pressure, which increases the speed potential of the bike.

The term "groupset" means mechanical components of a bicycle race, which excludes the frame, fork, wheel, bars, stems, pedals, saddle and seatpost. Changes Speed is an essential element of any groupset. These devices consist of a chain, multiple sprockets (toothed wheels), and a mechanism for changing a sprocket to another. This system is what allows the rider to adjust the speed and effort according to the field. The mechanism of change can be found in the stem of the bicycle, the handlebars or frame, but the full integration of systems use combined brake and shift levers that allow riders to change gears without moving his hand. Change of speed have been developed in the 19th century and, apart from the introduction of full integration, have changed very little since.

There are a number of different manufacturers to produce cassettes 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 often loyal to a mark on everyone else. As no component groupset, the mechanical elements of a road bike must weigh a minimum. Consequently, the Carbon fiber has become popular in the manufacture of these elements. They are used for levers, brake levers, spare cranks and gears.

I actually Trek 1.2 is listed below would be the best bike with the price tag at $ 879. One reason is the wheels. IMO Bontrager tires are better than me and Alex and Bontrager are we better conduct. As Sora Group, not a bad group. And I run it in one of my tricycle and since 1998 and have never had a problem with him, his great state. So if you upgrade or something rather not worry about the Tiagra go at least until the 105S earnings between Sora and Tiagra is minimal at best, and that the update would be a waste of money. Also with the Trek, you will receive an FSA (Full Speed Ahead) no Sora crank and cassette Sram is better than Sora, I would consider an update on their own.
