TYPES OF BICYCLES
A lot of people around the world uses the bicycle as a very convenient (and sometimes primary) means of transportation. And if countries such as China and India for this purpose are used the most basic bike, in European countries can be used and the most modern (though no surprise, and bike around in the road for decades). Also, a bicycle - is excellent for leisure and travel. And it could be as short trips out of town at the weekend, and about long-term autonomous transcontinental travel. On land there are virtually no places where it had not passed bicycle wheels. Also, a bicycle is actively used in the sport. If the road race are widely used since the beginning of XX century, some types of bicycles appeared little more than 20 years ago, but in spite of its short history, they have many supporters and fans, invented various accessories for the bike.
Road bikes
Road bikes are designed for high-speed movement on quality asphalt. These bikes you can see during the Olympics broadcasts or multi-day bicycle races such as Tour de France. With their design optimizes speed performance bike. Thus, they are easy with a small base frame, tightly-pumped thin wheels, for example, 700x22 mm, or with fine clincher (clincher - a special chamber with a lid) (up to 700x28 mm), wheel drop (rudder-horn ") . Ax manufacturing frames typically used carbon, aluminum, titanium and various types of high-alloy steels (eg chrome-molybdenum or magnesium). The design of bicycles for road racing team fixed rules UCI (Union Cicliste Internationale) in 1938, which later only adjusted, remaining essentially the same. Used to have a star can have a large gear ratios, usually a big star of the front has 53 teeth, and lower back - 12. This bike weighs 10.09 kg or even less. Typically, such bicycle ride trained people, beginners may have trouble because of his strength and agility (perceived untrained person as instability). Good road bikes and equipment for them are very expensive. Bicycles are used by professional cyclists, can cost from $ 10-20 thousand dollars. Just good roadies who use trained athletes cyclists, typically cost U.S. $ 1500-4000. Bicycles entry-level cost about $ 300. Among the manufacturers of quality road bike, for example, the company - Merida, Bianchi, Colnago, Look. Very close to road bikes is adjoined by two sub-types, firstly, that bike for a triathlon (do not fall under the UCI regulations), and, secondly, - bicycles for CycloCross (allow you to set a wider-road tires).
MTB (mountain bike)
In the mid 70'yh years in the U.S. became widespread biking in the mountains. Existing bike not suitable. For ease of driving in such conditions parties have make special bicycles. Primarily distinguished by their wide (about two inches, instead of the usual 20-40 mm) wheel slightly smaller than the road bike, the diameter (26 inches instead of 700 mm). The company also produces a special frame geometry, they were slightly less than normal, carriage (the axis around which the rotation of the pedals) to ride over rough terrain has been raised and they are distinguished by increased strength. Later, handicrafts moved to mass production of multimillion-modern mountain bike. Due to the fact that mountain bikes are operated in very difficult conditions, many new items, such as hydraulic brakes or suspension fork appeared exactly in MTB. Variety of solutions used in these bikes is impressive.
At present there are four main subtypes MTB:
Downhill bikes (Downhill)
Downhill - it is downhill from the mountains, that is, here we are not talking about that would just come down from the mountain bike, but whether that would come down as quickly as possible. In this regard, a bike designed for this type of a number of specific features. The main thing that distinguishes them is the increased reliability, that is, any failure could lead to the most unpredictable and therefore gives priority to construction of the fortress. They are equipped with very strong rudder, suspension fork, reliable brake (usually disk). The second group of features related to the fact that they were going down, respectively, the problem of minimizing the weight should not be used wide tires, the center of gravity shifted back.
Trial bikes (Trial)
Trial is to overcome obstacles. Bicycles are used in the Trial frame small size, light weight. Sometimes they have a front suspension fork, is sometimes used as a rigid fork. Brakes usually hydraulic, these brakes provide the best control.
Cross Country Bikes (Cross-Country)
High-speed cross-country. There may be as hard and with the suspension fork, the weight is minimized. Are made of carbon fiber or aluminum. Have much in common with bicycles CycloCross.
Friraydernye bikes (FreeRider)
The essence of these bikes as the name implies, they are designed for driving on rough terrain. They are not intended for any of the races and was in this context is not a pure subtype. Solutions are very diverse, can be as polnopodvesami, and have only a front suspension fork.
Road and mountain biking have in common is that both of these types have been developed to achieve maximum speeds in different conditions. When operating the mountain or road bikes cyclist is ready to sacrifice the simple operation of a bicycle and ride comfort in the name of a high velocity. I would like to note that the specific characteristics of each of these types most strongly manifested in older models. For younger models this applies only in part, that is, it is customary for riding bikes with some features (on inexpensive roadies, you will feel comfortable first and foremost on the asphalt, on inexpensive MTB - on dirt roads). Most other types of bike racks are located between the highways and mountain and took something from one of the types, and something - from each other and as they appear one more parameter - the comfort of the rider. For example, a tourist bike (touring) - is actually a variant of road bikes, adapted for long journeys. A bike class hubrid you'll often indistinguishable from MTB only slightly larger and less wide wheels.
Urban Bikes (city bike)
This is another extreme in the world of bicycles. From the name can be seen that these bikes are designed for riding around town. Here, priority is given to comfort of movement and ease of maintenance. City bike is very similar to well-known "road". Typically they use multi-speed planetary hub (eg type Shimano Nexus), almost maintenance free and allow the transfer switch in any state, not necessarily to pedal. There are multi-speed hub with the brake pedal, which makes such a bicycle while riding almost indistinguishable from the road. There are also designs with semi-and fully automatic transmission, which further make life easier for a rider.
Hybrids, hybrid bikes, hybrid bike (hybrid)
Even the name shows that this type of bikes combine the concept of both mountain and road bikes. They are designed for comfortable motion in different conditions, it is primarily a question of traffic on any roads in the city and the countryside there. If you look at some of these bikes in the directory that it has little distinguishable from MTB, they could just have the wheels, which makes them more elegant. The main difference between them on the MTB is the wheels, used 700 mm diameter wheels and tires with a width of 38-40 mm. These wheels allow quick movement. Typically used in hybrid'ax components / mounting of the mountain groups, sometimes specifically designed for these bike components such as Shimano Nexave. There are options such as with a rigid fork and with a specially designed bicycles for this type of depreciation. Despite many similarities, under this type of fall is very, very different bikes, for example, there are also bikes are very close in spirit to touring'am and bicycles are used in training athletes Triathletes. In general, the chrome-molybdenum or aluminum frames, sometimes even carbon fiber. Are the bikes in this class of approximately U.S. $ 300 to about $ 1500 U.S..
Hiking / touring bikes, travel bikes (touring)
Bikes in this class designed for tourism, and we can talk about how suburban trips to one or two days, and on multi-day trans-autonomous travel. Outwardly, they look like normal road bikes, but also have some differences from them. First, a frame developed for touring'ov are some differences in the geometry of the standard frames roadies, for example, have a large base, it makes these bikes more stable and allows you to comfortably move them to the goods. Also, the frames have greater strength and stiffness, usually at the expense of larger pipes, it is especially important when driving with the load. It's not that the frame of conventional roadies not hard or strong, just that they are designed to move on good asphalt roads. Frames are made of aluminum. It is possible to install roof racks (front and rear). Second, touring allow you to set the wheels with wide tires, up to 700x38 (roadies usual - up to 700x28). Ability to vary the width (and hence profile) rubber allows you to customize your bike under the proposed route. For a strong and heavy braking, especially important when driving with load, apply the brakes from the mountain groups (sometimes even hydraulic). Some companies for completing their touring use front shosseynye stars, and the rear - mountain, in some models use only highways stars, and some - just mountains. Each of the concepts has its pluses and minuses, so the combined mounting allows you to have a maximum range of gear ratios from 52/11 to 30/30, pure mountain headstock makes it comfortable to move in the mountainous relief. Bikes in this class do not come cheap, cost from $ 700-800 to $ 2000.
