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.
Fork travel
Front fork travel on bicycles with damped suspension (see "Suspension"). Roughly speaking, the travel of a fork is the maximum distance that its size can be reduced by compression during shock absorption. The longer the fork travel, the better the shock absorption and “soft” ride it provides, but not all bikes require a lot of travel. Even within the same type (see “Purpose”), depending on the specific application and riding style, the optimal fork travel will be different — for example,
freeride mountain bikes need good shock absorption, and for cross-country, on the contrary, a long fork travel will be redundant.
In general, if you do not plan on extreme cross-country riding or doing cycling tricks, this parameter is not critical. However, when choosing a bike for serious cycling, it is worth checking the recommended fork travel values (according to specialized literature or from professionals) and making sure that the desired model corresponds to them.
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 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.
Rear hub model
Model of the hub used in the rear wheel of a bicycle. See Front Hub Model for details.
Bottom bracket model
Model of the carriage installed on the bike as standard. The bottom bracket is the part that connects the system (front sprockets with pedals) and the frame; roughly speaking — an axle with bearings.
For details on the meaning of the model of a particular part, see "Cassette Model".
Front derailleur
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".
Rear derailleur
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".
Stem
Features of the handlebar stem (see "
Stem Adjustment ") installed on the bike. Here, both the offset model and its individual characteristics, most often the length and diameter, can be indicated. The stem itself can be either a separate part or an integral part of the steering wheel itself (the so-called integrated stem); the latter option is convenient in that the steering wheel cannot be skewed (unless broken), respectively, there is no need for centering.
As for the parameters, the rider’s landing depends on the length — the longer the takeaway, the more you will have to lean forward (ceteris paribus); strength and resistance to loads are directly related to the diameter; See “Cassette Model” for details on why the model name may be needed. It is worth noting that these parameters are important primarily for keen enthusiasts who pay attention to the smallest details in the characteristics of the machine; for most users, even advanced ones, such trifles are unlikely to be useful.
