Parts of a gear bike
The frame parts are the basic structure of the bicycle, and also the skeleton and main body of the bicycle, and other parts are also directly or indirectly installed on the frame. There are many structural forms of frame components, but they can be generally divided into two categories: men's frames and women's frames. The frame is generally welded and combined with ordinary carbon copper tubes.
To reduce tube weight and increase strength, higher-end bikes are built with low-alloy steel tubes. In order to reduce the resistance of fast driving, some bicycles also use streamlined steel pipes. Since the bicycle is driven by the human body's own driving force and riding skills, the frame becomes an important structure to withstand the impact load generated by the bicycle and whether it can carry the human body comfortably and safely. The quality of the ride will directly affect the safety, stability, and lightness of the ride. Generally speaking, the spokes are of equal diameter. In order to reduce gravity, there are also variable-diameter spokes with large ends and small middle ones, and flat and streamlined spokes in order to reduce air resistance.
Chains, also known as car chains and roller chains, are installed on even wheels and flywheels. Its function is to transmit the pedaling force from the crank and the sprocket to the flywheel and the rear wheel to drive the bicycle forward. Sprocket: Made of high-strength steel to ensure the required pulling force.
Divided into soft rim tires and hard rim tires. The soft-side tire has a wider section, can fully wrap the inner tube, and has a relatively large landing area, which is suitable for a variety of road driving. The hard-side tire has the advantages of light weight and small landing area, which is suitable for driving on flat roads, and has the advantages of low resistance and light driving. The pattern on the tire is to increase the friction with the ground. The tire width of mountain bikes is particularly wide, and the deep pattern is also suitable for off-road mountain use.
