1. What is the timing of using the front and rear brakes and how to allocate them?
Front and rear brakes should be a topic that many friends and many knights have been discussing, as long as there is an Internet connection, that is, when should front brakes be used? In other words, should I use the front and rear brakes together, or, when I use the front and rear brakes together, should I use the rear brake first and then the front brake? Or there are many sayings that when I ride on the track above the stadium, do I only use the front brake? In other words, whether GP riders or riders over the years only use the front brakes, this is really too much to say.
First of all, a concept. The locomotive factory will try to reduce the cost and reduce the weight to help you steal light. It is not to make your car very light. It is not because you know that you will steal the weight and help you reduce the weight. It saves costs, so he will definitely remove the things that shouldn’t be there or don’t need them. That’s good for braking. If the rear brake is not needed, he definitely removes it, because the first one saves costs. So on the BOM list, if he thinks that this thing shouldn’t be there, he will definitely remove it, and he will definitely help you get rid of it, saving costs.
As for how to use the front and rear brakes? You have to think about one thing first, why you need it, there is a rear brake, because if you don’t need it, the car factory will remove it for you, so according to the above statement, the rear brake is absolutely necessary, so use it. In fact, when we decelerate, most of the brakes will be used before, because it can support the inertia of the whole car forward. Why is this? For example, we have seen a more extreme example. The front brake must be dual-disc on a publicly upgraded imitation racing car, and the front calipers must be better, but will it remove the rear brake? No, it will also have brake discs and calipers behind it, but it’s just saying that it may use a smaller brake disc, and it must be a single disc. Then its caliper form is relatively simple and very The simple idea is that the ratio of its braking force is probably the front big and the back small, so when we operate the force, we also operate according to the principle of big front and small back. We also operate according to the big front and small rear. The principle is to do proportional deployment.
Generally speaking, I think that on the road, your possible strength will be 6 to 4 or 7 to 3. It is probably this kind of strength to adjust your brakes, which also depends on whether you have people Or the load has some relationship. For example, if we have a man in the back seat today, so you can imagine that there will be a person’s weight on the rear wheel. So at this time, the ratio of you using the rear brake will increase, and the ratio of the rear brake will increase. For example, it might be 7 to 3, or 8 to 2, so we have people in the back at this time. Adjusted to 6:4 means that the rear brake needs to be used more. So when there are people and loads, your concept is that the rear brake must be used more because it carries a heavier weight. In addition, this is also the same as It matters how slowly you brake.
In addition, the brake ratio will also have something to do with your braking force. We are in the safety drive. For example, the stationmaster has been to Suzuka safety drive twice. His requirement for the brake is that you must use the rear brake, not excessive The front brake is used, so we just mentioned that in terms of strength, it must be that the front brake is used more and the rear brake is used less. But in terms of driving safety, if we need to stop the vehicle safely today, that is to say, if we are not going to brake suddenly, but to practice stopping the vehicle safely, then you must rely more on your rear brake. Technology. In other words, in our operation, you will press the front and rear brakes together, and when you are about to stop, you will slowly release the brakes again, so as not to cause excessive sinking of the front fork. This is the first level, the first level of practice is to brake, we first slow down is the practice of the first level of braking, we use a stable braking force, while using the front and rear brakes to make the vehicle stop steadily. This time is not in a panic situation.
So when you come here, you must know that the front and rear brakes must be used together, and in terms of braking force, the front will be heavier and the rear will be lighter. But according to the fact that you are carrying more and more people or carrying more and more people, then the rear brake will be used more, and then it is what we just said, and then it is what we just mentioned, if you are slowing down more gently, Your front and rear brakes must be used together so that your center of gravity will not shift to the front wheels excessively.
If it is a more extreme braking, we need to slow down the vehicle quickly. The station master will tell you at this time that most of the force in the operation will be on the front wheels, because when the brakes are urgently braked, the center of gravity will actually shift to the front wheels. Go, that means you have to rely on the front wheels to support the weight of the whole car. Another one mentioned here is that the grip of your front wheels is very important. If your grip is not enough, even if you brake harder, the front wheel may not be able to catch the ground and cause you to crash, so this is not a question of force distribution, but how about you, not exceeding the tire limit. Of course, if your tire limit is too low, it will easily be exceeded and will lock up. When we use most of our strength on the front brake, your mastery of strength is very important at this time. Generally speaking, the rear wheel brake will be an auxiliary force at this time, probably 9:1, because we are on a normal road, if you want to make an emergency brake, you must focus on the front wheel brake. Power control, but the rear brake is probably slightly, stepped slightly with a steady force, and let the front wheel do the main braking force. This is when we have to do a sudden deceleration or emergency situation. The method used, for example, I am currently on the track, I actually use the front and rear brakes together, and the main force is placed on the front wheel, the rear wheel just maintains a certain force, about 10% of the force is stepped on, and steady Step on the ground, so that it can maintain some stable power of the rear wheels. In this situation, the grip of the front and rear wheels are used together. In this case, your braking force will be more stable, and you can make a deceleration movement relatively quickly, which is probably the case.
Actually, I think there are a lot of details in it. I will ask readers to ask more in-depth words. Let’s talk about it separately, but the general idea is that the front and rear brakes must be used together. There is a problem of force distribution. Then you will have more in the general situation, maybe six to four or seven to three. If in an emergency situation, probably most of your attention will be transferred to the front brake to use, probably the strength can be said to be nine to one. How about this ratio on the track? I myself currently use nine front brakes and one rear brake to make a sharp deceleration before entering the corner.
2. What are the effects of using the front brake and the rear brake during cornering?
The brake is a tool that allows you to adjust the speed. When do you adjust the speed? Of course, you have to adjust the speed before entering the corner. You have to remember that the brake is a tool to adjust the speed. You must adjust the speed before entering the corner. For example, if we are above Beiyi, you might add a little throttle on the straight line to increase the speed. When you see a curve, you know that you should slow down, lower the speed again, and then enter the corner. Basic rhythm.
Whether it’s on the track, our general road, or even the mountain road, the truth is the same. When you encounter the intersection ahead today, of course you should lower your speed first, and then lower it to a proper speed before you make the turn. This is the basic principle. You must lower your speed before entering the turn. Do the brakes only after hitting, for example, if you enter the corner today, you find that the speed is too fast, and then you do the brakes. This is absolutely very dangerous. Because your tires are already starting to provide you with lateral grip, it may have used 70% of its grip. At this time, if you add a little braking force, it is very likely that the first one will lose the grip. If it is the previous brake, you are likely to stop and the body will stand up and it will have a natural Reaction, it may stand up, and then it may run out, so the original line may be able to corner without any problem, but if you suddenly increase the braking force, you may stand up and throw out .
Of course, there are also some actions that will do the rear brake, that is, you will bring a little rear brake in the corner. To put it simply, it means that you continuously reduce your speed when you are in a corner, so that your vehicle can turn a relatively small corner. It is such a simple idea. However, if you have already adjusted your speed before the corner, then you don’t actually need to continuously adjust your speed during the corner, you can already be ready to exit the corner, so whether it’s on a mountain road or on a track Inside, when you are in a corner, you are generally ready to exit the corner. You can bring a little throttle to make the vehicle more stable. If you are still slowing down at this time, on the track, you must lose others, on the mountain road, you must be dangerous. Simply put, it is better to slow down and go into the corner. practice.
Especially for novices, this is definitely something you must remember, control the speed before going into the corner. Of course, if we talk more carefully, if you bring in a little rear brake today, it is true that you can make your corners smaller and smaller because you lower the speed. So if you bring a little rear brake The brakes will be like this, but if you use the front brakes, especially when you enter a corner, you suddenly slow down. First, you may lose your grip, or in other words, your vehicle will float slightly. After the righting, you may throw it out, so if you are a novice, know this first. Don’t brake suddenly in a corner. There will definitely be bad consequences. Even if you brake suddenly on the rear wheels, you may suddenly lock up. , Causing the rear wheels to slip out.
3. Regarding the shift of the center of gravity, how should the buttocks move so that the body does not shake?
Before entering the corner, for example, if we are good on the track, we will not mention the general road. For the track, we will definitely make a shift of focus, which is to turn people’s buttocks and knight’s buttocks into the curve. Move inside. We actually see this on the GP. How do you move your butt today is a logical question. Do you twist your butt with your waist? In other words, you use your ass to twist the muscles on both sides like this. This sounds strange, so the only reasonable thing is that you use your thighs to move your ass. If you twist it with your waist, you will cause friction, or if you move your buttocks with muscles today, your car will twist and twist like this, and every time you twist it, it will sway.
A better way is to clamp the fuel tank with your thighs and move your butt over. Everyone can try it on the car. After you clamp the fuel tank, use the strength of your thighs to move the butt out. You also need to do more compliant movements. Twist vigorously, the car will go in the opposite direction, which is the force and reaction force. If you twist to the right, the car will sway to the left. At this time, if your tire grip is not so good, if you say If you use GoPro to shoot the rear wheel, you may see that the rear wheel will shift, so use the strength of your thighs to move your center of gravity inward first. At this time, generally speaking, we will move in a straight line. So in a straight line, you will be less affected. Even if you really use too much strength at the beginning of the practice, you will still keep going straight with a slight stroke on the straight line.
But if you only move in a bend, then you have already started to fall. At this time, if you move suddenly, it may be that moment to make your rear wheel slide out, and at this time the tracking system It can’t save you, because you have used up the grip, not because the power is too strong, you can limit the power to save your rear wheels. In fact, it is because the grip has reached its limit, especially in the lateral direction. Even if the power is limited, it is useless and cannot be saved.
Pay special attention here. Just before entering the corner, you should slightly shift your center of gravity to the inside. This will help you to corner. As I mentioned last time, this is actually a basic idea of cornering. If you want to bend inward or to the right, then your person must also follow to the right, so of course it will be on the inner side, whether it is you doing a lower body movement, or we just put the upper body slightly inward This is a very basic idea, that is, if we go this way, the human body will bring a little bit inward to help the car go through the corner together. This is like a philosophy. Of course, we don’t say that the car goes to the right. It’s weird if we walk in the opposite direction. This is a philosophy that I think, a bit like riding, that is, we bring the car together. It will be smoother to get in.
4. How to adjust the riding posture for long-distance travel so that you won’t be tired?
To be honest, this question is very practical. The station master thinks that it is better in terms of the type of vehicle. In fact, you have to avoid long-term fatigue. First, you must train your muscles and endurance well, because if you try to escape, you will have nothing. After playing, you must have the most basic endurance. The sore muscles are the muscle groups nearby. I think the most important thing for cycling is your core. It will help to exercise the abdominal and back muscles.
Of course, if you are already on the road, how to avoid fatigue? Simply put, you have to change postures, that is, you have to find a few postures whether you can still maintain a basic riding posture. Keep your hands bent, and keep your back arched a little, don’t be too straight. During this, you can still change a little bit to ride. Generally speaking, the fastest way to change the riding position is the position before and after you sit, because it is difficult for you to adjust the handle quickly unless you have a strap. Tools, or in other words, it’s difficult for you to adjust the position of the pedals right away, but what you can change in time when you are in the car is the position of your buttocks, so you find it easy to ride in front of you, and sit a little behind. It’s also easy to ride. Just change your posture during the journey, and the muscles can be relieved. That is, you might use the front muscles, but now you might use the back muscles, or the angle of your entire back. A little change can be made.
Actually speaking, Scooter is the best way to change posture, because the cushions are usually full. You can sit a little bit in front and a little bit behind. Then the position of your feet is also good. It usually has flat feet. Position, there will be a rest pedal in front of the pedal, that is, your feet can be stretched slightly, then you can step on the back a little bit, or even step on the foot pedals of the back seat, although this is not very good, but just let You can change your posture a bit, and his cushion is relatively long. You can ride a little bit in the middle, a little bit in front, and a little bit behind. You can still maintain a position that you can control with ease. In fact, I think it’s probably a change of posture. The same reasonable riding action in a reasonable posture. But you make a little change to adjust.
Of course, I think before going on the road, if you say that you are riding an imitation car, your pedal position, if you can adjust it, maybe you usually have higher pedals on mountain roads or on the track. Remember to lower it when you go to the roundabout, so that your feet have more space and will not bend for a long time. Even I think the helmet is the same. For example, we will be used to wearing tighter helmets on the track, and the head support will be better. But if it is such a helmet, you usually wear three consecutive times. In ten minutes to an hour, you will start to feel a little stressed, so this is to say that, in fact, the hats we wear on the track may be a little different from the hats used for riding. Otherwise, frankly speaking, you will not be able to stand the pressure and go cycling with a painful head. This is also unreasonable. Although we want to say that there is a certain degree of tightness, the strength that everyone can bear is still different. Then you may be able to ride for 30 minutes to an hour with such a force, but after an hour you will definitely hurt, you My head hurts, how do I ride a bike? There is really no way, so some of your tightness, or the position of your feet, is to make some adjustments according to your long-distance riding conditions. This is inevitable, and there is no way, because people’s endurance is limited.
5. The choice of the cornering route is always poor. Where would you suggest to start to improve?
I think the basic idea of choosing a route is the so-called outside, inside, and outside, which is back to what I just mentioned. In fact, I don’t think it’s a technique, it’s more like a riding philosophy, because you turn. When you turn in, of course you turn in from the outside to change into the inside, and then in the process of centering the body, it becomes the so-called outside again. So outside, inside and outside it is not a way of drawing lines, it is when you are turning, you Put the car in from upright and straighten it. I think this in itself is a so-called outside, inside and outside.
In fact, if we apply it to route selection. I think it’s generally safer to ride outside, inside, and inside on mountain roads, because we are in judgment, and it’s hard for you to judge. After I cut from outside to inside today, it’s safe for me to return to the outside. Yes, you may find that you have entered the corner, but it hasn’t finished the turn. You have started to straighten, and you may be riding outside, so many people rush when exiting the corner. In the opposite lane, generally speaking, you will not be in the corner, nor will you enter the corner. When you enter the corner, it may be that your speed is too fast and you can’t turn in at all, so you rush toward the opposite direction.
This brings us back to what we just said that you must lower your speed when you enter the corner, but when you adjust the speed or the line, there may still be what I just said, even if you control the speed of the corner. , But because you are not familiar with this corner, it hasn’t finished turning and you’re already on the inside of the corner, you will rush to the opposite side, and when you exit the corner, you rush to the opposite side, because you find that your car can’t turn at all In the past, it is better to be more conservative and inside. For example, when you enter the corner, you may be slightly outside, so that you can see the entire corner better, and you probably know the corner well. How will you go? You start to dump and stick in, and then maintain this inside line to continue to exit the corner, you will not have to exit the corner, and then you will ride in the middle to the opposite lane, or in addition to the opposite lane, there are also doubts It may be a mountain wall. The other side may be a mountain wall. If it is a left turn, then if the right side is a mountain wall, you may be thrown outside in the second half of the turn, so conservative riding on general roads or your line idea It is better to go outside and inside. In other words, if we walk outside and inside the center, it means that when you exit the corner, you have a certain amount of leeway, that is, you will not find it as soon as you exit the corner and you will immediately walk to the opposite side.
In other words, we have to be more conservative when riding, that is, the speed of entering the corner, and then a little bit slower, so that the speed of the entire turn is within your ability or within the limits of the so-called car. , Don’t exceed the limit easily. If you are not lucky, you may hit a mountain wall, hit an oncoming car, or ride down a mountain slope. When you have been walking on the edge, this situation is easy to occur. So I think this is the basic idea of a curve, that is, you have to make sure you are optimistic on the outside and understand how the whole curve will go again. Sticking in is dumping. It is a process of going in, then going out. When cornering, try not to stick out quickly, but take an outside, inside, or inside or outside, inside and center, so that you can accelerate out of the corner smoothly. I think this is the safest and fun way to do it. It’s like this.
