What Types Of Mountain Bike Parts Are There?

Called by the ideas of "building a healthy body" and "energy saving and emission reduction", more and more people have become cyclists. I ride a bike to buy groceries at work, ride a bike for leisure on weekends, and occasionally have to go for a long-distance ride. For them, cycling has become a part of life.

Stepping into the cycling circle, how can you not have a car of your own? Before deciding to buy a car, you must have a preliminary understanding of the bicycle!

Next, take a mountain bike as an example, and teach you how to identify its structure and main accessories

1. Bike frame

Generally speaking, the frame of a car includes components such as frame, front fork, stem, handlebar, vice handle, seat tube, seat and headset. Since other parts are installed on the frame formed by these parts, it can be called the soul of a car.

For cyclists, when buying a bicycle, you really need to take a good look at the frame and choose its material carefully. Generally speaking, frame materials are divided into: aluminum alloy, carbon steel, titanium alloy, carbon fiber, etc. You can choose the appropriate one according to your own needs and budget.

2. Wheel system

The wheel system consists of hub (axle), spokes, rim, inner tube and outer tire. Among them, the hub, spokes, and rims form the wheel set, which is the key to determining whether the bicycle rolls smoothly. In addition, when you replace these accessories, you must pay attention to the size so that the two ends do not fall.

In addition to the wheel set, everyone should pay attention to the tires. Thick tires and good grip are the main characteristics of mountain bikes, and the material of the tires, the arrangement, shape and depth of the tire patterns and grains determine the performance of the tires. The pattern on the tire is to increase the friction with the ground. The tire width of the mountain bike is particularly wide and the pattern is deep, which is also suitable for off-road mountain use.

3. Transmission system

The transmission system of a bicycle includes a pedal, a crank, a chainring, a central axis, a chain, and a flywheel. Among them, the most well-known ones are the crankset and the flywheel. Next, Xiao Di will talk about them.

The flywheel is a wheel-shaped accumulator with a large moment of inertia installed on the rotary shaft of the machine. When the speed of the machine increases, the kinetic energy of the flywheel increases and the energy is stored; when the speed of the machine decreases, the kinetic energy of the flywheel decreases and the energy is released. Flywheels can be used to reduce speed fluctuations during mechanical operation.

Chainset, the part connected to the crank. The crank is driven by pedaling, and then the crankshaft is driven to rotate, and finally the rear wheel is driven to rotate through the chain and flywheel to provide power and complete the entire transmission chain of the bicycle.

In addition, the ratio of the number of teeth to the number of teeth of the flywheel is called the transmission ratio. The higher the transmission ratio, the easier it is to ride and pedal. The better the rigidity of the sprocket and the more precise the production, the higher the pedaling efficiency.

4. Speed change system

The transmission system includes the transmission (finger or handle), front and rear derailleurs, and transmission lines. The grade and adjustment of the transmission system affect the smoothness of the transmission. There may be compatibility issues between different brands. This factor needs to be considered when matching.

The function of the mountain bike transmission kit is equivalent to the transmission system of the car. By matching different gears, that is, by changing the cooperation of the chain and the gear plates of different front and rear sizes, the speed of the vehicle can be changed to cope with riding up and down slopes and headwinds. Cycling environment.

The size of the front chainring and the size of the rear chainring determine how hard the bike spins the pedals. The larger the front chainring and the smaller the rear chainring, the harder it is to pedal. The smaller the front chainring and the larger the rear chainring, the easier it is to pedal. Riders can adjust the speed of the bicycle by adjusting the size of the front and rear chainrings according to their own abilities, or cope with different road sections and road conditions.

5. Brake system

The braking system is respectively the brake handle, the brake line and the brake. Generally speaking, the commonly used brakes are V brakes and disc brakes. The specific advantages and disadvantages are as follows:

The characteristics of V brakes are light weight, cheap price, mature technology, and easy maintenance. The disadvantage is that it has requirements for the environment, the effect is not good in rainy days, and it wears the rim.

Disc brakes are relatively heavier, more expensive, and not easy to maintain, but they don’t wear the rim, and the braking effect is better. They are not afraid of the impact of sand, gravel and muddy water. When it rains or snows, its braking effect can be clearly reflected come out.
