Comparison AZIMUT Voltage FR-D 26 vs AZIMUT Blaster 26

The presence or absence of a depreciation system on a bicycle, as well as the type of this system.

— Without depreciation (rigid). In such models, the wheels are fixed directly to the rigid elements of the frame; there are no depreciation devices. Due to this, the design of the bicycle is simple, the weight is small, the cyclist feels all the features of the road topography as much as possible, and the maximum efficiency of pedaling is also achieved, which is important, for example, for road models (see "Destination"). At the same time, structural rigidity is a "double-edged sword". On the one hand, "feeling for the road" is important for BMX and some mountain models (see "Purpose"); on the other hand, the lack of shock absorption significantly increases the load on both the structure and the rider himself, leads to increased wear, fatigue and some risk of injury on rough roads.

— Depreciation of the front fork (hard tail). The most popular type of cushioning in adult bikes (see "Age Group"), especially urban and mountain types (see "Purpose"). In accordance with the name, in such bicycles, the shock-absorbing device is installed only on the front fork, while the rear wheel is rigidly fixed. The presence of a shock absorber somewhat increases the weight of the structure and complicates its maintenance, however, the advantages of such a scheme significantl...y outweigh the disadvantages: hard-tails combine good handling, “road feel” and ride comfort, including and on rough terrain.

— Rear fork. Bicycles in which only the rear wheel is damped, while the front wheel is rigidly fixed. The rear shock absorber is designed to provide additional comfort when hitting various bumps, and the absence of a front shock absorber reduces the overall cost of the machine. This option is found mainly in urban models, including electric bicycles (see "Application"); in other varieties, the use of rear shock absorption is not practical.

— Two-suspension (full suspension). Bicycles equipped with shock absorbers on both wheels — a fork in front and a special suspension in the back. Such models are as comfortable as possible for driving on rough terrain, because. They dampen the vibrations felt by the cyclist best and provide the best grip on uneven tracks. At the same time, the presence of a rear shock absorber "eats" part of the energy coming from the pedals, and you have to spend more effort to ride. To avoid this, many two-suspension bikes can be provided with front and rear suspension lockouts (see below), but full suspension complicates the design anyway, increases its weight and price. Therefore, this type of cushioning is relatively rare, mainly in certain varieties of mountain bikes (in particular, for cross-country and freeride; see "Purpose").

Type of rear suspension damping in full suspension bicycles (see "Suspension"). To date, there are such options:

• Spring-elastomer.
• Spring-oil.
• Air-oil.
• Air.

The first three options are described in detail above in the "Type of cushioning (fork)" section above. In air systems, as the name implies, the working element is air, which acts as both a damper and a shock absorber. This is very convenient due to the ability to change the stiffness of the suspension by adjusting the pressure in the system — the higher the pressure, the harder the damping. However, such shock absorbers are prone to rapid failure due to wear of the seals and require more careful maintenance than similar air-oil shock absorbers in many respects.

Tyre model supplied with the bike as standard. Different tyres have different purposes and characteristics; knowing the tyre model, you can clarify these points and check how they correspond to your wishes. This is especially important when choosing a machine for serious cycling.

Model of a cassette — a system of rear wheel gears — mounted on a bicycle. Cassettes of different models differ in characteristics and can belong to different classes — from entry-level to professional. Knowing the cassette model, you can get acquainted with its features in more detail (according to official documentation, reviews, user reviews, etc.). This is especially important when choosing a bike for professional cycling.

Model of the derailleur (derailer) installed on the carriage with pedals as standard on the bike. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".

Model of the derailleur (derailer) installed on the rear wheel cassette as standard on the bike. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".

The model of the shifters (see “Shifter type”) that are fitted to the bike as standard. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".

Additional equipment supplied with the bike.

— Wings. Protective devices in the form of shields that are installed over the wheels and protect the cyclist and others from water and dirt flying from the wheels while riding. Usually, they are made removable — in case you need to minimize the weight of the car.

— Saddle with springs. A saddle equipped with springs that make it softer and provide cushioning. Note that soft spring-loaded saddles are designed mainly for a calm, leisurely ride — for high-speed bikes (including advanced road bikers), narrow hard saddles are considered more suitable.

— Shield on the chain. Protective shield covering the bicycle chain. Note that the dimensions and design of such a shield can be different: in some models it covers the entire upper section of the chain from the front to the rear sprocket, in others it protects only the front sprocket itself from the outside. Anyway, the main task of such a device is to protect the chain from foreign objects, primarily the edges of the cyclist's clothing. The shield can be made removable — in case you need to reduce weight.

— Footboard. A device in the form of a small folding pin that provides additional support. With a footrest, the bike does not need to be leaned on a pole, wall, fence, etc. — it can be placed vertically on an...y relatively flat surface. Note that many bikes without a kickstand allow you to buy and install it separately.

— Peggy. Special devices installed on the axles of "stunt" bikes — BMX or mountain bikes of the corresponding specialization (see "Application"). Pegs look like extensions of axes pointing in both directions. The standard size of one such "continuation" is 11 cm in length and 4 cm in diameter. They are used for a variety of acrobatic routines, ranging from riding on pegs to sliding on edges, railings, etc.

— Boot. A classic bike rack is a platform for carrying various cargoes, mounted above the rear wheel. It is found mainly in city bikes (see "Application"), as well as some relatively simple mountain and road models. Separately, we note that it is at least highly discouraged to carry passengers on the boot, and in many countries it is expressly prohibited by traffic rules.

— Front boot. Boot (see above), located above the front wheel. The advantage of this arrangement is that the transported luggage is constantly in front of the cyclist's eyes. On the other hand, the front rack is usually attached to the steering wheel and turns with it; thus, the additional load can significantly complicate management. Therefore, this feature is relatively rare, usually as an addition to the traditional (rear) boot; the exception is tourism models (see "Application").

— Basket on the steering wheel. A basket for transporting various goods, installed in front of the steering wheel, above the front wheel; a kind of analogue of the front boot described above. At the same time, on the one hand, the basket is more massive, on the other hand, it is better suited for transporting large items or numerous small items. In addition, the cargo on the boot needs to be additionally secured, while this is not always required for the basket.

— Signal / call. A bell or other sound signal — for example, a horn — usually mounted on the steering wheel, at the cyclist's hand. This equipment is very useful for warning other road users of an approaching bicycle. And in some countries, the presence of a sound signal is mandatory according to traffic rules.

— Lighting equipment. In this case, the presence of a headlight, a taillight, and in some cases, both at once, may be implied; specific configuration should be specified separately. Anyway, such equipment is indispensable for riding at night: it makes the cyclist visible to other road users, and the headlight also illuminates the road. In many countries, traffic rules expressly prohibit driving at night without lights.

— Bottle holder. Dedicated water bottle holder, usually mounted on the frame. It is more convenient to carry a supply of water with you on such a mount than to keep a bottle in a backpack, bag, on the boot, etc. Some bike models with this function are immediately equipped with a bottle, for others it needs to be purchased separately.

— Pump. The presence of the pump in the delivery set eliminates the need to buy it separately; in addition, the “native” pump initially fits the existing mounts, while problems may arise with a third-party one. Note that most often the kit comes with relatively simple and compact hand pumps; they are not designed for large volumes of work, but they can quite cope with everyday tasks like pumping a flat tyre.
