the variable speed system is actually composed of dial, forward dial, rear dial, and transmission line. It refers to the controller. The forward dial controls the position of the chain on three tooth disks on the tooth disk, and the back dial controls the position of the chain on the flywheel. by adjusting the position of the chain on the tooth disk and flywheel, change the tooth ratio to produce a variable speed effect.
after the ratio of teeth changes, the feeling of the cyclists pedaling on their legs may change. This change is more powerful or less powerful. Many new people think that if they want to ride fast, they must step on hard, so we often see that riding with very large teeth ratio (front with a large plate, followed by a small flywheel ). In fact, this is wrong. Riding speed is affected by two factors: 1 is the frequency, 2 is the power. Both are indispensable.
the frequency indicates the number of times the leg is trampled in one minute. The reasonable frequency is about 90 per minute. The cycle drivers generally ride in a large group at this frequency. The frequency of cross-country cycling is slightly higher than this. If you want to ride faster, increasing the frequency is the first priority. During the sprint, professional players can step on 140 of the terrorism.
many new TX do not have the concept of stepping frequency. If you want to ride faster, you can directly use the super-large ratio of 3x8 and 3x9. Because your legs are not powerful enough, you cannot step on a 90-foot frequency. Therefore, the speed is more than 30, and the average speed is difficult to maintain. Riding the same speed will lead to fatigue than people with the correct frequency. I use 2x8 teeth to speed up to 52 on a flat road, but I cannot ride 3x9.
therefore, the correct frequency setting is the most critical pedaling Technology for our amateurs.
Some people may say that after reading the above frequency setting content, what should I do if I keep a 90-foot-rate, but I feel a little empty and too light? I want to ride faster?
In fact, you need to change the tooth ratio at this time, indicating that your strength can adapt to a larger tooth ratio. After the speed change, the leg strength felt increased, but it was still able to maintain a 90-foot frequency, and the speed of riding was significantly improved.
how can we ride faster and maintain a longer time? At this time, the frequency and strength should be both taken into account. For example, when I climb the Longquan mountains and ride together with daqiang, the frequency of the two of us is the same, but the ratio of the teeth used by daqiang is 2*8, because my leg strength is not as powerful as my heart and lung ability, I can't step on this position. I only use 2*6, so it took 21 minutes for the strong to open the mouth, and I used 25 minutes. He can have more than 25 AVS, and I only have about 20.
After talking about this, our amateurs should first exercise to maintain a reasonable frequency and improve the strength of their legs.
To maintain the frequency, you need to use multiple variable speeds. The Olympic contestants frequently use variable speeds to maintain the best efficiency of pedaling. We are not athletes. We ride for fitness and for more fun, so we also need to adjust the tooth ratio with variable speed to make the muscles feel less tired and more comfortable. At this time, the 9-speed system is relatively 8-speed, and the advantage of the 7-speed system is reflected. The 9-speed system is not as simple as a flywheel with an 8-speed system. The 9-speed system is more than the 8-speed system, so the tooth ratio can be more delicate, so that you can more easily find the most suitable tooth ratio during the speed change, it is not easy to return a block, you may feel tired when you step in. Road vehicles are very frequency-conscious, so now the road car entry kit uses 10 speed.
Except for activities, several dingtalk users who climb the hill will basically not correctly use the variable-speed Tx. The speed change on a sports bicycle is different from that on a general civil vehicle. It is durable and designed to be stable and used normally. It can be used for many years. You can use the speed change with peace of mind to give full play to its expected functions.
My skills are limited and I can only write them at the entry level. If you have any mistakes, please correct them. I hope you can discuss them and improve the pedaling technology together.
