Everyone in the cycling circle knows that mountain bikes are equipped with transmission system, which also brings great convenience to our cycling. But do you think the transmission of mountain bikes simply increases speed? In fact, the role of the transmission is to help riders maximize the power of trampling, which is directly reflected in the speed increase.
Of course, for beginners, it may be too difficult to adjust the transmission, and it is difficult to find the best gear ratio for themselves. However, if you spend a long time and master certain skills, you will surely achieve unexpected results!
What is the role of mountain bike transmission?
Generally speaking, the most intuitive function of the transmission is to adjust the gears to adapt to different road conditions, so that the rider can get the best riding effect with the smallest force. In addition, the transmission can also help cyclists to reduce energy consumption effectively in the case of poor physical strength.
If you suddenly feel that trampling is very hard and the pedal seems to be very heavy, you can adjust the transmission at this time, and you can easily trample by changing to lighter gears. Conversely, you need to transfer to heavier gears.
In addition to the above description, the transmission can be divided into external and internal transmission, as follows:
A large range of transmission ratio can be obtained by using multi-stage tower-shaped teeth and matching different numerical teeth with chains.
Advantages: Easy maintenance, clear transmission effect
Disadvantage: The structure is basically exposed to dust and foreign matter, causing damage.
Internal speed change
The variable speed structure is integrated into the bicycle flower drum, and the transmission ratio is changed by the transmission between gears with different teeth.
Advantages: Structural seal, not affected by the outside world, generally without frequent maintenance.
Disadvantages: Complex structure, thicker shell, heavy quality.
What is the principle of mountain bike transmission?
Many people are curious: Is the transmission really so amazing? What is its working principle? Next, Xiaodi will elaborate on the principle of the transmission to help riders understand its regulation more clearly.
When a cyclist tramples, the force is amplified by the “chains” and then transmitted to the “flywheel” by the chains. The “flywheel” then drives the rear wheels to rotate, thus driving the bicycle forward. In short, the transmission changes the forward speed by making use of the different teeth ratio between the chain disk and the flywheel.
When the “big plate” of the chain disc is combined with the “small fly” of the flywheel, the “big plate” rotates once and the “small fly” rotates many times, so the “small fly” will drive the rear wheel forward for a long distance, so the speed of the car is the fastest at this time, of course, the rider will pay more power.
When the “small disc” of the chain disc and the “big fly” of the flywheel are combined, the “small disc” rotates one circle, and the “big fly” rotates a few circles, so that the “big fly” will drive the rear wheel forward a little distance, so at this time the speed of the car is the slowest, while the power of the rider is the smallest.
These misunderstandings should be avoided when cyclists change gears!
When a novice enters the cycle, he may not know enough about the transmission, so that he can not keep the pedal frequency through the gearshift in time and correctly, which is also unable to really understand the wonder of the speed change. Next, Xiaodi will come to check the errors that may arise when a novice changes speed, and you will remember to avoid them.
Fixed Tooth Ratio Riding
Mountain bike riding process, may encounter different road conditions, cyclists need to use a reasonable speed change, so that they can trample more effectively. If the mountain bike cross-country, cyclists need to use the transmission more reasonably, sometimes in a very short time to switch gears several times.
If the fixed teeth ratio for a long time cycling, not only will make the rider spend unnecessary energy, resulting in muscle soreness, physical fatigue and other symptoms, but also make flywheel, disc, chain wear and tear increase, and may have irreversible damage to the knee joint!
