Max weight
The maximum load allowed for a bicycle is, in other words, the maximum weight that it can normally carry in normal use. Of course, when calculating the load, the weight of both the cyclist himself and the additional load that he carries with him is taken into account.
The permissible load must definitely not be exceeded: even if the bike does not break down immediately, off-design loads can weaken the structure, and an accident can occur at any time. Also note that it is desirable to have a certain weight margin — at least 15 – 20 kg: this can be useful in case of transporting heavy loads and will give an additional guarantee in emergency situations (for example, when a wheel gets into a pit). Considering that the average weight of an adult is about 70 – 80 kg, bicycles with a permissible load
of up to 100 kg can be classified as "lightweights",
from 100 to 120 kg — to the middle category,
more than 120 kg — to "heavy trucks".
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.
Freewheel/cassette model
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.
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".
Chain model
Model of the chain supplied as standard with the bike. For details on the value of the Model parameter for any part, see 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.
Handlebar model
The model of the handlebar supplied as standard with the bike. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".
Pedal model
Model of the pedals supplied with the bicycle. See Cassette Model for details on why you might need the model name of a particular part.
