6 reasons causing hydraulic brakes to rub against the disc: 1. you have to make sure your wheels are installed in place. For non-bucket axle wheels, first, confirm whether your wheels have been installed in place. Open the quick release, press the frame with your body, and then lock the quick release in place. Incorrect installation will cause the disc to tilt against the disc. For the barrel axle wheelset, before adjusting the position of the brake caliper, the barrel axle rod must be locked to a predetermined torque and then adjusted to prevent the disc position from changing after disassembling the wheelset. 2. Confirm whether there is any play in your wheel axis. Special attention should be paid to the wheelset of the ball structure. Once the bearing has a play, no matter how you adjust the position of the caliper, the disc will always be rubbed. So before adjusting the calipers, move the wheel frame to make sure that there is no play on the left and right sides of the wheel. If the bearing hub has a clearance or shaking, deep maintenance and bearing replacement are required. 3. Confirm whether the disc has large yaw. Although the discs are more or less swaying, if your bike has a disc after being transported or crashed, you’d better check whether the disc is deformed first. If the deformation is not very large, just rub the disc without being stuck, you can use the disc correction wrench to adjust. First, find the position of the deformation, use the correcting wrench to insert it along the disc support rib, and correct it in the opposite direction of the deformation. Note that you can make multiple corrections according to the situation, and avoid doing miracles with great effort. 4. Make sure that the calipers are up so that there is enough gap between the disc and the disc. This situation often occurs in brake systems that use DOT Brake Fluid oil. Because DOT Brake Fluid oil has water absorption, it will cause the gap to become smaller when the oil expands. This situation can be solved by replacing the dot oil with a new one. On the brakes that use mineral oil, it is mostly caused by excessive oil injection or excessive thickness of the disc. Depending on the situation, the piston reset wrench can be used to withstand the brake pad and discharge excess brake fluid from the oil filling port on the brake lever, thereby increasing the gap between the brake pad and the caliper. In addition, on some high-end brakes, you can slightly adjust the piston clearance by adjusting the preload of the brake lever piston. 5. Confirm that the movement of the pistons on both sides of the caliper is synchronized and that there is no immobile or sticky piston on one side. 6. Confirm the cause of the abnormal noise. Not all rubbing discs appear in the left and right positions, they may also appear in the up and down positions. Because the edges of different discs will have different textures, coupled with compatibility problems of different discs and calipers, and the fixing position of the mounting screws or the disc itself, there will be radial jumps and rubbing against the top of the calipers. The solution is simple: add a 1-2mm spacer between the frame mount or adapter and the caliper and fix it with screws again. Method of adjusting disc brake caliper (oil pressure): After you eliminate the above six reasons, if you still rub the disc, it will be a good solution. For hydraulic brakes, only the fixed position of the caliper needs to be adjusted. We have mentioned that the fixing screw hole of the caliper is oval and has the ability to adjust left and right. Regardless of the fixing method, including flat-mounted calipers, direct-mounted calipers, the way of installing through the adapter, the adjustment method is the same. My most common method is to first loosen the two fixing screws so that the caliper can move freely and then tighten the caliper fixing screws while pinching the brake lever. Generally speaking, this method has a half chance of success for calipers with tapered spacers. For ordinary direct-fixed calipers, the general situation at this time is that the disc will be close to the incoming film on one side. Next, loosen one of the fixing screws and gently loosen the other fixing screw until the caliper can rotate around it. Then adjust the position of the caliper on the side of the loosened screw, adjust it to the center, and then tighten the screw. The same method to adjust the other end. This method is relatively easy to control the adjustment range, and it is not easy to cause the caliper to shift again due to the fixing screw. It should be noted that if the caliper is not supplied with a tapered washer, do not add it to the caliper. This aspect will cause the caliper to rise, resulting in a reduction in the contact surface and the weakening of the braking force. Another point is that some calipers will aggravate the situation that the disc is not centered. Method of adjusting disc brake caliper (mechanical): For mechanical disc brakes, the method is the same as that of hydraulic brakes. The difference is that the pads on both sides of the mechanical brake have a more free adjustment range. Most of the mechanical brakes are single-piston motions, such as the MD-M300 of Yanhao TEKTRO, the position of the discs can be adjusted on both sides of the brake. The movable side can be adjusted by the tension of the brake cable, and the non-movable side can be adjusted by the fixing screw. I usually make the movable side of the film stick out less, and the inactive side to make the film stick out more. The position of the disc is closer to the movable piston side, and the left and right gap ratios are about 1:2. If it is a bilateral piston motion mechanical brake, such as trp’s spyre. It can be adjusted according to the same left and right gap. The angle and spacing of the brake lever Generally speaking, the angle of the brake lever is the extension line from the arm to the handlebar to the back of the hand under the normal cycling posture, and the first joint of the brake finger is the most suitable place to put the brake lever on the brake lever. Of course, this is just a basic adjustment angle. If some cyclists have other hobbies, then comfort prevails. Regarding the distance between the brake lever and the finger, it can be adjusted by the fine adjustment screw on the brake lever. For the more high-end brakes, the adjustment knob is directly equipped, and most of the low-end brakes need to be adjusted from the position of the brake lever and the piston link through a 2mm hexagon wrench. The relative position of the brake lever and the fingers is to maintain the grip posture, and the first joint of the index finger is just right on the turning point of the end of the brake lever. If it is a two-finger or three-finger brake lever, the position of the outermost finger shall prevail.
Cycling and running are both popular aerobic exercises. In fact, compared to running, cycling can achieve better results. Why? Let’s take a look together! First, Comparison of body changes between running and cycling 1. Number of heartbeats Although riding a bicycle is relatively easy, in terms of changes in the number of heartbeats, the heartbeat of a bicycle has a greater change. The greater the change in a heartbeat, the greater the burden on the body, so the greater the amount of exercise. Therefore, the advantage of cycling is that it feels very relaxed, but the amount of physical exercise can be achieved quickly! 2. Calorie consumption On the surface, it seems that the calorie consumption of running is more than double that of a bicycle, but because of the different time spent, if the average calorie consumption per minute is used, the calorie consumption of the two is similar. The data of the two are very close, but relatively speaking, cycling is much easier. (Because the speed is faster, it feels windy, the body temperature is easy to drop, and you will not feel tired.) Second, Important findings of cycling exercise Experimental results: 1. Running can strengthen the muscles of the calf 2. Cycling can strengthen thigh muscles, psoas muscles (iliopsoas muscles) The main function of the thigh muscles is to weigh and lift the feet, so they must be exercised well. The unfamiliar psoas muscle (iliopsoas muscle) is also used to support the body, but its importance is not lost to the thigh muscle, because if the psoas muscle is weak, people will not be able to stand for a long time and will be easily ill in bed. In addition to cycling, the other exercise to exercise the psoas muscles is to climb stairs. However, climbing stairs will allow the knees to bear the weight of the whole body, which is not suitable for the elderly. Therefore, if the elderly want to train the psoas muscles, riding a bicycle is the most suitable. Third, Use small slopes for muscle training Muscle strength training in recent studies has found that more than 30% of your own maximum muscle strength must be used to improve muscle strength. Without this level of strength training, the muscles may still weaken. So how do you ride a bicycle to use 30% of your own maximum muscle strength? Experiments have found that 1.25% of the slope can be reached by riding 50 meters. Fourth, cycling can make blood vessels younger After exercise, the speed of blood flow increases, and nitric oxide is produced. The function of nitric oxide is to soften the muscles surrounding the blood vessels. The faster the blood flows, the more nitric oxide is produced. Experiments have found that cycling can speed up the flow of blood ten times. Therefore, friends with vascular diseases, you can consider riding a bicycle to improve blood vessels! Fifth, expert advice Running and cycling are both aerobic exercises, which can make blood vessels younger, lose weight and prevent diseases caused by lifestyle habits. However, running does not improve muscle strength. How long does it take to ride a bicycle to make blood vessels really younger? Expert advice: Cyclists under 40 need to ride 180 minutes+ a week; 40-year-old cyclists need to ride 160 points+ a week; 50-year-old.cyclists need to ride 150 points+ a week; 60-year-old cyclists need to ride 140 points+ a week.
In the morning, at noon, or at night, when would you choose to exercise? Of course, your exercise time is limited by your work and study. However, if you can choose arbitrarily, is there an optimal exercise time? Experts say: Yes. But this time depends to a large extent on yourself. In recent years, scientists have been constantly exploring the relationship between the biological clock and exercise, in order to find a time that can consume the most fat every day. It turns out that changes in body temperature will affect the quality and effect of exercise to the greatest extent. In other words, when you exercise, the higher your body temperature, the better the effect of your exercise. Usually, the body temperature is the lowest within 1 to 3 hours before waking up, and it will rise to the highest in the afternoon. Therefore, it can be said with certainty that the best time for exercise is in the afternoon. During this time, your muscles are warm, full of energy, steady heart rate, and have low blood pressure. But scientists also warn that don’t think that the law of the biological clock determines everything. The best time for your exercise depends on whether you can do it on time. To arrange the time in a time that will not affect normal work, and don’t always think about the body’s biological clock. Before deciding when to exercise, you’d better ask yourself two questions. First, what is your work and rest time? Are you busy in the afternoon or evening? Is morning exercise more suitable for you? Or, is it necessary for you to adjust your morning, afternoon, or evening exercise? Second, when do you feel your best? Do you have trouble getting up in the morning? Are you the kind of procrastinator? In that case, you will definitely be ranked last for exercise. You may think that you are more active in the morning, you are in the best state and you are willing to exercise in the morning, but have you ever thought that you still have a whole day to do and you still need more energy to deal with the day’s affairs. But ironically, early morning exercise has one of the biggest advantages over afternoon exercise: it is easier for people to persevere. Because at this time, there will be no scheduling conflicts in exercise, and people will not be distracted by other things. Perseverance is a very important factor in exercise. However, no matter what time you choose, follow the suggestions below to make your exercise more effective and more fun. Exercise in the morning: 1. Put away the clothes for the next day at night. When the alarm goes off, you can jump up directly instead of looking for clothes and shoes everywhere. 2. Set up two alarm clocks, one by the bed and one in the room, which can prevent you from being lazy. 3. Find a partner. Usually, it’s fun to work out with a partner, so why not add this to your exercise plan? When you want to be lazy or give up, your partner will remind you and urge you to persevere. Exercise in the afternoon or evening: 1. Determine the exercise time and stick to it. Don’t let other things distract you and give up exercise. Try your best to schedule the time for Sunday night. If you have any small adjustments, you can, but it must not affect the achievement of your goals. 2. If you exercise outdoors, pay attention to safety. Prevent heatstroke and dehydration in summer. Drink plenty of water.
Why do some bicycle enthusiasts switch mountain bikes to road bikes? I think it may be caused by two factors: changes in personal interests and hobbies and actual cycling. First, look at the advantages and disadvantages of mountain bikes and road bikes. Mountain bikes, as the name suggests, are more suitable for cycling on mountainous and rugged roads. The frame of mountain bikes is more rugged, strong, and has better shock absorption performance. Mountain bikes have front fork shock absorbers, and some have rear shock absorbers. Wide cycling comfort is higher, generally wider straight handles are used, and the handling is better, but the resistance is relatively large and the speed is relatively slow when cycling. Road bikes are mainly used for cycling on highways or on relatively flat roads. In order to increase speed and reduce wind resistance, the frame is relatively slender. Generally, there is no shock absorption mechanism. The bending handles are used. When cycling, you need to lean down, the seat is narrow and long, and the cycling comfort is Slightly inferior to mountain bikes, but cycling faster and faster. Secondly, it depends on factors such as the cycling environment and daily use frequency of mountain bikes and road bikes. Mountain bikes can ride on rugged roads such as mountains or on roads, while road bikes can only ride on roads or flat roads, not off-road. It should be said that the cycling environment of mountain bikes is more extensive.Daily commuting to and from get off work, regardless of whether the pipeline conditions are unobstructed, the general cycling distance is not too large, and the cycling comfort of mountain bikes is higher. It is also easier to park temporarily. Road bikes are inferior to mountain bikes in many aspects such as comfort and temporary parking. However, there are not many people who really ride mountain bikes to cross-country cycling, and most places do not have a really suitable cycling environment. If you go to professional venues or “wild” venues to ride, either you need to pay, or there is a great danger. From a safety point of view, the risk of cycling a mountain bike off-road is significantly higher than cycling a road bike. And cycling a mountain bike off-road requires learning more off-road skills and mastering more relevant knowledge. Most people ride on ordinary roads or relatively flat places, and very few people go for real off-road cycling. The shock absorption performance of mountain bikes is almost useless. There are also very few places suitable for cycling in the city. It is not easy to ride where there are many steps. Third, one of the biggest disadvantages of mountain bikes compared to road bikes is speed. The mountain bike frame is rough and heavy, and the cycling posture is mainly sitting or standing, resulting in greater wind resistance during cycling. The width of the mountain bike tires causes the resistance to increase, and the number of teeth and front and rear gear ratios of the chain wheel is slightly smaller than that of the road bike, leading to cycling There is a big difference in speed. There is not much difference in speed between mountain bikes and road bikes when cycling in the city. Once cycling on an open road, the speed difference will be very obvious. It is very normal for a road bike to reach a speed of about 30 kilometers per hour. The average speed of a frequent rider can even reach about 40 kilometers or even higher, and the instantaneous speed can even exceed 60 kilometers or even higher. Professional cyclists ride at an average speed of about 40 kilometers per hour. If they ride a TT time bike, they will be faster than ordinary road bikes. The picture below is the TT time bike, because the seat tube angle is slightly larger than that of ordinary road bikes, and the body position and center of gravity are more forward, which is more conducive to the force of the thigh and avoids excessive force of the calf. In addition, the special design of the handle makes cycling speed is faster. Fourth, many cyclists choose road cycling rather than off-road cycling when cycling outdoors. Because of the obvious speed advantage of road bikes, mountain bikes have obvious disadvantages in speed when cycling on the road. And many people ride with other people, and few like to ride alone like me. When we are together, we can’t keep up with others, so we can only rely on physical strength to make up for the disadvantages of mountain bikes. Over time, many people gave up mountain bikes and chose road bikes. I rode a road bike with my classmates on a mountain bike. It was nearly 50 kilometers back and forth. When I reached a speed of 30 kilometers per hour, I didn’t feel too tired. My classmates felt a bit difficult to ride a mountain bike.I think it is the disadvantage of cycling speed that makes many people who ride mountain bikes switch to road bikes. Although the road bike itself has a slight disadvantage in terms of comfort, it can completely make up for this disadvantage by replacing more comfortable seats and cycling clothes. Leaning and cycling while cycling may make people who are just starting to ride feel uncomfortable, but as long as you adapt to a stage and exercise your core strength and other muscles, you can adapt. The feeling of cycling a road bike is very refreshing. You can feel the wind blowing over your body and the scenery on both sides passing by. Mountain bikes can’t give this feeling. Under normal circumstances, riders choose mountain bikes and road bikes. I recommend choosing road bikes instead of mountain bikes. There is now a model that is between mountain bikes and road bikes. It basically uses a reduced version of the mountain bike frame, plus front fork shock absorbers, and some also add rear shock absorbers, plus road bikes or The width of the handlebars of mountain bikes is between that of mountain bikes and road bikes, taking into account the comfort and speed of long-distance cycling. This kind of bicycle is more suitable for cycling, and it is better to choose a pure road bike for people who do not have this need.
“How heavy is your bike?” This question may have been asked by many people, but does a mountain bike be good if it is light? Does the weight of the bike really mean that the bike is poor? Does the quality of your ride depend entirely on the weight of the bike? Or should we completely stop pursuing the stupid behavior of lightweight? Light means it is a good bike, and a heavy one means it is a low-end bike. This is a saying that bicycles have been circulating for decades. Since the 1990s, this situation has continued for quite some time, and many drivers have spent a lot of time or even their lives for this, and even the handlebars will break due to daily punctures. Fortunately, due to continuous testing and production process improvement, the problem of strength and safety for many years seems to have been resolved. However, the importance of the weight surface has not diminished. With the hollow rear derailleur and the slender handlebars, everything was losing weight in the 1980s, and the quality of cycling has long been forgotten. This is the fact, mountain bikes have indeed become heavier in the past two years This sounds like a paradox: weight has long been the decisive factor in mountain bikes, so it seems that technology is undoubtedly regressing. But the fact is that in recent years, Lindau and Enduro models have become heavier and heavier. But does this ruin the mountain bike? Not at all! As the weight increases, the handling becomes easier and the cycling becomes more fun. Since the emergence of mountain bikes, the speed of their development has surprised you. In the beginning, suspension forks and disc brakes were used, which slightly increased the weight. Then came the lifting seat tube, larger wheel diameter, wider handlebars, and so on. Don’t we need these changes? Of course not! Over the years, mountain bikes have changed from boring bikes to the forest to a tool for descending the mountain, providing the greatest pleasure for various routes. Now, you can easily use a 140mm travel mountain and spend a day on the bike park-which was unthinkable a few years ago. What used to be a track that only DH could control has become a road that is easily crushed by modern forest road bikes. The frame has also become heavier, but it has also become more complex, stiffer, and more reliable The ever-improving performance of bicycles causes cyclists to ride on increasingly rough roads at higher and higher speeds. The increased stress on the frame may increase wear and tear due to the selection of accessories. It goes without saying that the frame and bearings must adapt to such changes. This is the case with the new Canyon Spectral, Canyon’s product manager Daniel Oster said: The frame does become heavier, but now Spectral and Strive to have the same characteristics. And thanks to the new connecting rod design, integrated internal wiring, frame protection device, and improved seat tube clamp, it becomes more durable and reliable. For Canyon, durability and low maintenance, and customer safety are much more important than those few grams of weight. To give another example, Specialized can completely give up SWAT to make the Enduro or Stumpjumper frame lighter, but why not? Because it is more convenient, don’t you think it’s easier to go out and ride a bike without having to carry a backpack? Reliability should be the first priority. For the time and money spent on replacing the bearing of the turning point, why not choose to ride more? DH accessories appearing on forest roads and Enduro bikes With the development of technology, as long as you are careful, you can easily install a 12kg forest road or 13kg enduro mountain. But, who wants to use those soft, thin-walled tires? With this alone, you can save nearly 500g of weight on a single wheel, but is it necessary? Another example is brakes. Previously, Shimano’s saint brakes were only used for DH downhill bikes. Now, you will see more and more enduro mountain bikes with oversized calipers. Some enduro bikes even use 200mm discs to improve safety and braking power. This will undoubtedly increase weight, and likewise, the fun will increase. Powerful brakes, more gripping tires, and lifting seat tube all greatly increase the weight of the bike (the actual weight will increase by about 1kg). In the past few years, the manufacturing process should become more advanced, and the materials have become lighter and stronger, but the weight of mountain bikes is still increasing. What does this mean? Have you thought about it? Despite getting heavier, the climbing performance has become better There is a prejudice: a bicycle that is too heavy is not suitable for climbing, but what factors really need to be considered when climbing? Weight or the position of the cushion? Larger seat tube angle and shock-absorbing structure? Many models have proven that despite the heavy-duty frame and strong downhill performance, they can also have strong climbing performance as long as the geometry is right. With the right seat cushion, you will find that the weight of the bicycle is irrelevant. Improve downhill handling For many people, this sounds difficult to understand, but adding a little weight in the right place can actually improve the handling of the bike. eMTBs are a good proof, especially in real high-speed and demanding routes. Their weight gives you great confidence and provides excellent lateral grip. Visionary Chris Porter even put lead blocks in the frame to test. This is obviously an extreme example, but the thinking about bicycle weight is commendable. The weight of eMTB is not necessarily a disadvantage. According to my personal understanding, the key to electric power-assisted mountains is that the motors and batteries are mainly added to the bottom bracket and the down tube. The center of gravity of people and bicycles is moved down, which brings more stable handling and excellent lateral grip. This is not the same as simply adding weight to the bike. For a simple example, you can fill the tires with water to increase the weight. The increase is quite obvious, and you don’t have to think about it to know that the cycling experience is rubbish. This industry is self-adapted When a new product, such as a new suspension fork, is released, the weight should drop unless a reasonable reason is found to increase the weight. For product managers, weight is always a factor to consider when developing new parts, because the product has to face too many competitors. Brands always pay attention to the total weight when launching new models, so as to encourage suppliers not to make the kit too heavy. For this reason, the weights of bicycles with similar positioning and configuration are relatively close. What if modern mountain bikes are too heavy for you? What if you don’t need these so-called performances, safety, and durability? If you are just looking for a lightweight mountain that can ride on gravel roads, or climb as fast as possible, and you are not in a hurry to descend? The solution is simple: please buy an XC model. Many brands have launched XC-level soft-tail models, such as Trifox MFM100 Carbon Fiber Full Suspension MTB Frame, which are more suitable for you who are pursuing lightweight. For those who only ride gravel trails and junior cross-country trails, XC is a better choice The weight of the weight has dropped A few years ago, it was very simple to compare which bike was more powerful. However, with the different wheel diameters and the increasing differentiation of applicable uses, it becomes more difficult to judge the quality of mountain bikes. As mentioned earlier, different tire choices or suitable tubeless tires will increase the bike by hundreds of grams. Therefore, judging the quality of mountain bikes by weight has long been outdated.
Let's talk about wired and wireless cycling stopwatches. Many friends like to measure their speed per hour and the distance of long-distance riding through the cycling stopwatch. Of course, it is very convenient to download the cycling notes to record the usual trajectory. But according to personal needs to install the cycling stopwatch, the current cycling stopwatch is mainly divided into two types of wired and wireless, do you think is the wired cycling stopwatch is better or wireless? Wired cycling stopwatch Wired cycling stopwatches mainly transmit sensor signals through data cables, and are currently the most used type of cycling stopwatches. Advantages: The performance is relatively stable, the speed measurement is relatively accurate, and it is not easy to interfere. As long as a small battery can work alone, the power consumption is very low, and the price is usually relatively cheap. Some cycling stopwatches are waterproof, the sensor is more sensitive, and it also has a luminous effect. Disadvantages: The installation of a wired cycling stopwatch is relatively troublesome, and it affects the overall appearance of the bike. Wireless cycling stopwatch The wireless cycling stopwatch actually has an external sensor and magnetic head, but it does not need to use a data cable to transmit the model, and directly receive it wirelessly. Advantages: The installation of the wireless cycling stopwatch is relatively simple and convenient and does not affect the overall appearance of the bike, the sensitivity of the sensor is stronger, and the functional design is more diverse and intelligent. Disadvantages: Although the speed of a better quality wireless cycling stopwatch is accurate, the price is relatively high. For example, the wireless cycling stopwatches of Japan CATEYE. Generally, wireless cycling stopwatches whose price is less than USD 50 are inaccurate and their performance is unstable. Will often be disturbed during use. Which is better, wireless or wired? Through the above introduction, you can find that although the wireless cycling stopwatch is fashionable and beautiful, it is either relatively expensive or poor in quality, while the wired cycling stopwatch affects the appearance of the bike, but it has stable performance and strong anti-interference, and The price is cheap, so I can’t tell which one is better here. It depends on the individual. if you don’t want to spend much money, just download the mobile APP record directly, which is also excellent.
Want to make your cycling experience better every time? Then don't make low-level mistakes before cycling. Before cycling, make sure that the bicycle is clean and tidy and all functions are normal. If you want to make your next cycling experience better, you must prepare well before you go. Preparation means not only what you need to do, but also Including the things you can't do. Here are a few things you need to avoid before cycling: Excessive intake of high-calorie and high-fiber substances You should eat some easily digestible foods before cycling. High-fat and high-fiber foods are not a good choice. Ingesting high-fiber foods, such as salads or non-starchy vegetables, takes time to digest, so it will last longer in the stomach. Similarly, foods with high-fat content should not be taken. Because these foods will not be digested quickly, it is not good for you who want to maintain a good physical condition before cycling. This means that these things cannot be converted into energy transmission to your muscles immediately. Instead, you can consume some carbohydrates or lean protein. Filling too much water Water, of course, is a necessity, but nothing is too much. This is the unchangeable law. If there is no way to replenish water in time on the road, you may want to fill it with two or three bottles first. Dear, this is definitely a bad idea. Your stomach and kidneys can’t bear such a lot of “pressure” at once. Drinking too much water will only make you feel bloated, and you often want to go to the bathroom when cycling. And drinking too much water can cause hyponatremia. Although this happens rarely, the clinical symptoms it causes can appear to be dizziness, fatigue, and nausea. The best way is to slowly take in about 450 grams of water 1-2 hours before cycling so that it is almost exhausted before cycling. During the ride, just drink one or two sips every 15 to 20 minutes with a little supplement water will do. Don’t check the gear shift before cycling For those with long-distance cycling plans, it is really not a good thing to discover that the brakes are not working after 20 minutes of cycling. It is recommended to check your bicycle accessories quickly before cycling, such as whether the tires are broken, whether the brakes are still working, or whether the pedal lock shoe splint is broken, etc. these conditions will be dangerous to your cycling. ” he said. If you want to take a cycling trip, it’s best to check it a few days in advance. If there is a problem, you can also leave some time to go to the bicycle shop to find a technician to repair it. Make sure the chain is correct. Sensitive, your wheels are not scratched, and the brakes work. Do static stretching exercises Of course, stretching is not a bad thing in itself, but it’s not a good idea to do some static stretching before your muscles are fully active. However, there is still some controversy regarding this matter, but most studies have shown that doing static stretching exercises before exercise can actually weaken your muscle’s function. Do some simple pedaling exercises to warm up 10 minutes before cycling. Of course, the role of static stretching exercise is still very good for cyclists, but it is best to do it after the end of the ride. Do not tell others where you are going before cycling Imagine that you are injured or lost. Although it is not as effective as this situation, you need to take precautions in advance. Let your friends know where you are going before cycling, it’s best to bring your ID card. At the same time, you have to tell them how long you plan to ride. Needless to say, bring your mobile phone. Finally, the best way is to open social software. The most important point is that when you are really injured, the insider can quickly find you.
Not everyone can go downhill like a professional cyclist, but at least you can optimize your downhill movements through some tips, increase your confidence and speed when going downhill! If you can’t go downhill happily, why bother to ride up the top of the slope? When cyclists face downhills, many people will have an inexplicable sense of fear, but that’s okay, you might as well listen to our suggestions, then take your bike and try it out on a slope! 【Cycling Posture】 Imagine that you are cycling on a road bike. Lower your body as much as possible and try to get as close to your bike as possible. If you are not used to this posture and feel uncomfortable, then try a few more times. Until you get used to it. Because when you lower your body, the center of gravity will also become lower, so that when you go downhill at high speed, you can increase the stability of your bike. Of course, this posture is also easier to control the brakes, because the distance is closer, and the range of contact becomes larger. At the same time, try to keep your back in a straight line, and then lift your head slightly, so that you can more easily observe the field of vision in front of the bicycle. 【Route Selection】 If you want a better downhill experience, then choosing a suitable cycling route is very important. Of course, you can choose any mountain, any road is right, but the flatter the road means the faster the downhill speed will be, thus reducing the difficulty of the downhill. In addition, the rule of cornering is: take the outer road before entering the bend, take the inner road when entering the bend, and take the outer road when exiting the bend. According to this method, you can control the speed and ensure the maximum friction, so that you can pass smoothly when turning. 【Brake】 When it comes to speed control, it’s time to talk about braking and the timing of braking. When you are going downhill, remember to press the brake lever in advance before turning. In this way, when cornering, there is no need to brake to control the speed of the bike. This can increase the friction of the bike, because high-speed rotating wheels have better grip than slow-rotating wheels. In addition, when preparing to brake, you must remember to brake gently and continuously until you can feel the effect of the brake. Then gradually increase the force of the brake and slow down until you feel that this speed is sufficient for cornering, then release the brake, maintain the speed, and ride along the downhill route! The main precautions for cornering in the above manual. But on the smooth road between the curve and the curve, you have to change your cycling posture. At this time, you can straighten your body slightly and prepare for the next curve. Even at this time, you can still be lazy. Step on the pedal a few fewer times and slow down until you regain your confidence. Be sure to maintain a steady breathing rhythm during the process and try to relax as much as possible. This will ensure that you are in good control of the bike, both physically and psychologically. That’s almost it, let’s briefly summarize what I said above. 1. When going downhill, make sure that your posture is correct; 2. Press down the body as much as possible, keep your fingers within the controllable range of the brake at all times, and look forward; 3. When you pass the first turn, slowly ride to the outside road and prepare to brake. When braking, you must ensure that the speed is low enough to facilitate your cornering; 4. When entering a curve, release the brake and keep the outer pedal at a low position; 5. Ride on the outside road when exiting a turn. This will ensure your speed and preparation for the next turn. As for self-confidence downhill, I want to say that safety comes first. If you are not sure if you are doing this right, then put safety first. In short, it is important to control the speed of the bike downhill. If the speed is beyond your control, you should brake as soon as possible before turning. Hot tip: When the ground board is very wet, the bike’s grip will be weakened. When you are on duty, you must brake twice as early as usual, and the speed must be controlled at half the usual speed, so as to maintain your control of the bicycle.
The width, angle, and elevation of the handlebar directly affect the handling and comfort of the bicycle. So, is the width and angle of the handlebar really important? Below, we will talk about how to correctly choose the width and angle of the handlebar through the three most common types of mountain bikes. XC handlebar width and angle selection As the only mountain bike event in the Olympics, the current xc track is becoming more and more complex, the wheel diameter is getting bigger and bigger, and there are more and more types of handlebars, such as integrated handlebars. Compared with the other two models, the xc climbs more slopes. Now, most xc riders will choose a longer negative angle stem. The handlebar width is generally 640～740mm. The handlebar is generally 640~740mm in order to exert force and press the front wheel. Bring good support to the cradle. The angle of the handlebars is also relatively forward, but due to the increasingly rugged and complex terrain and the use of 29-inch wheel diameters, many professional drivers have chosen handlebars with a 5-10 degree lift, which can ensure the efficiency of climbing. At the same time, it brings a certain improvement to the stability of the downhill bike control and flying over the platform. Personally, I feel that the xc handlebars can now be selected from 680 to 700mm, and the angle can remain unchanged. If you are interested, you can try. Enduro handlebar width and angle selection The adjustment of the front and rear shock absorbers directly affects your position on the bike, so before choosing the handlebar height, make sure that the front and rear shock absorbers have been adjusted. Unlike roads, mountain bikes are more flexible, so there is no “recommended” absolute handlebar height. Handlebar lifting is subjective and depends on your own personal preferences, height, choice of bike, and terrain. However, the “extremely low” and “extremely high” heights of some foreign professionals often appear in the video, which may help you find a lift that suits you. For enduro models, the handlebar lift generally tends to be between 20 degrees and 35 degrees. Because this is not only conducive to uphill force but also can bring stable control to downhill. The 780mm handlebar width is more suitable for the shoulder width of our Asians. Now, most of the original handlebars are 800mm, and many people buy them and install them directly. This will lose your strength and control of the bicycle in climbing and downhill, especially cycling on a narrow forest road. It is also a big test for your control. As the current handlebars are somewhat drifting behind (the angle of the handlebar’s backward offset is about 5-15 degrees), the installation angle can be selected as far back as possible in the middle (there is a digital scale on the handlebar, and different brands of scales Mean different). Because of the offset of those few degrees, the feeling and confidence of lifting the front of the bicycle and controlling the bicycle will be greatly increased, but the installation angle should not be too backward, so it will be very strange when going uphill and it will not be sent. force. After confirming the width, try both the front and back angles to find the angle that suits you. DH handlebar width and angle selection In Red Bull Rampage (Red Bull Rampage), the various gods operate so smoothly, the choice of handlebars is also crucial. DH handlebars are mainly divided into two types, racing type, and action type. For racing type, you can choose a handlebar with a lower elevation (20-30 degrees). The same is true. The width of 780mm is more suitable for us Asians (if Your shoulder width is enough, you can use 800mm). The handlebars of downhill bikes are mainly for bike control, and the angle can be selected to be centered and rearward, and the center of gravity is relatively backward when going downhill to improve stability. If you are an action-type DH player, you can choose to raise the handlebars higher (about 30-40 degrees), and the width can also be relatively reduced, about 740mm~780mm, which is convenient for making “perfect” movements when flying bags in the chartered field.
