Frame size

Frame size refers to the distance from the saddle attachment point to the bottom bracket attachment point (axles with gears and pedals). The main parameters that determine the choice of a bike for frame size are the height of the user, the purpose of the bike and the intended riding style.It is also worth considering the female frame, which is lowered, which allows you to ride comfortably even in a skirt or dress.

User height is the most significant factor. In general, the taller the user, the larger the frame should be. The universal formula that allows you to calculate a specific size is as follows: the length of the leg from the groin to the heel in centimeters must be multiplied by 0.6, and then divided by 2.5 — you get the approximate size of the frame in inches. But in the characteristics of brands, the frame can also be indicated in the usual form for measuring size XXS, XS, S, M, L, XL and XXL.

However, note that this value is very arbitrary and approximate, it can only be used for simple bicycles not intended for extreme driving (for example, city bikes, see "Destination"). If you choose a more specialized model (mountain, road, BMX) — it is better to refer to the tables for th...e appropriate type, because. sizes for one height can vary significantly depending on the destination. In addition, different manufacturers have different frame geometry and measurement methods, and therefore, for the most accurate selection, it is recommended to use the manufacturers' own tables.

Note that the optimal frame size is not absolute — in most cases, for the same height, “neighboring” sizes are quite suitable. And here it is worth paying attention to the intended driving style. It is believed that small, well-controlled frames are better suited for extreme variant, and larger and more stable ones are better suited for long-term calm movement.

Recommended height

The user's height recommended by the manufacturer is calculated according to several parameters. One is the wheel diameter, and the second and more important is the frame size. If everything is simple with the wheel size — it is round and always the same, then the frame size complicates the choice. Different types of bicycles have their own frame shape, so even the same size can be suitable for different heights. And this is not to mention the features of the manufacturer, who like to do everything for themselves, and not in a general manner. Therefore, the size of the frame of each bicycle has its own size and it is still better to choose a bicycle by personally “saddling” it. If this is not possible, then our point will tell you what height, according to the manufacturer, this configuration (frame + wheel) of the bike is designed for.

Size

In this case, we mean the French marking of the size of bicycle tires. It is recorded in the “700x35C” format. The first number determines the outer size of the tire in millimetres, the second — is the width of the tire, and the letter of the Latin alphabet from “A” to “D” indicates the internal (landing) size. “A” is the smallest size, “D” is the largest. The marking is found on tires for road, hybrid and city bicycles, but tires for mountain bikes are not marked with it.

Tyre

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.

Front brake model

Model of the brake used on the front wheel of a bicycle.

Knowing a specific brand of brake system components, you can find technical documentation for it or, for example, study brake reviews on the Internet. For more information about the types of brakes on the front wheel, see "Front brake".

Front rotor

Front rotor.

The front disc brake rotor is a perforated metal plate attached to the wheel hub. The reduction in speed of the bike occurs as a result of the compression of the brake disc by the pads, which are driven by cable tension (in mechanical type systems) or by means of a hydraulic circuit (in hydraulic disc brakes). The diameter of the front rotor can vary from 140mm to 220mm. The higher the number, the more efficient the brake is.

Rear brake model

Model of the brake used on the rear wheel of a bicycle.

Knowing a specific brand of brake system components, you can find technical documentation for it or, for example, study brake reviews on the Internet. For more information about the types of brakes on the rear wheel, see "Rear brake".

Rear rotor

Rear rotor.

An element of a disc brake system mounted on the hub of the rear wheel of a bicycle. It is to him that the pads are pressed when the brake lever is pressed. The use of a rotor ensures high braking efficiency. And it is higher, the larger the diameter of the rear rotor. Disc rotors are available in sizes 140, 160, 180, 185, 203 and 220 mm.

Front hub model

The model of the hub used in the front wheel of a bicycle.

The hub is the central part in the wheel through which the axis of rotation passes. Features of the behavior of a bicycle depend on its characteristics, in particular, “rolling” (the ability to move by inertia, without pedaling). Knowing the model of the front hub, you can clarify its characteristics according to the manufacturer's documentation, find reviews from other users, etc., in order to determine how this model suits you.
