Riding a bicycle often encounters headwinds. The wind greatly hinders riding. So how to save effort when riding a bicycle against the wind? What are the techniques for riding a bicycle when headwind or uphill?When cycling on slopes and upwind:What to do if you encounter uphill and headwinds? Our experience is that we should first ride the bike at our original strength and rest several times when we are tired. Do not rest too long each time, just 5-10 minutes.When it is difficult to climb on a steep slope, you can walk along the zigzag line to reduce the slope. Sometimes I can't ride on a steep slope or even the car will back down.Don't be afraid at this time. People on variable-speed bikes can lower the speed and move up slowly. Riders don't have to worry. My experience is to lift the handlebar with both hands so that the legs can be pushed down more forcefully. Move your body's center of gravity forward, and move your feet forward from the pedals. Use the part near your heels to touch the pedals, which makes it easier to exert force. Then press your thighs and calves to pedal directly through the roots of your feet.In this way, with the help of bodyweight and thighs, the force can be directly transmitted to the bicycle pedal through the calf and the root of the foot (using the toes and soles will disperse the force and will also make the soles of the feet fatigue), thereby increasing the pedaling strength, and the bicycle will slowly get on. Po, won't retreat anymore.Of course, cycling is the most tiring in this situation, and everyone has to do what they can. Pay attention to safety when walking uphill in the "Zigzag" shape. The slope is often the steepest at the transition point. Pay attention to passing vehicles. When riding on steep slopes, you should get off the bike and rest for a while before getting on. The elderly and the weak should get off the bike. Climbing a hill is very tiring and requires people's physical strength and perseverance, but it can make bicycle travel more interesting and aftertaste. Once on the top of the hill, you can have a unique enjoyment.Cycling is the biggest headache when encountering headwinds. Although it is difficult to go uphill, the next step is to go downhill, which can be relaxing for a while. Sometimes when headwinds are downhill, it is not easy to ride. At this time, you can lower the handlebar, bend your arms and stay under the handlebars, and lower your head to lower your body's center of gravity to reduce wind resistance.When you lower your head, the field of view is narrowed. Always pay attention to safety, especially when encountering headwinds and headwinds. Be careful and pay attention to passing vehicles, because at this time, whether it is a car coming from the front or behind, especially a large truck, the bicycle will be left and right. Accidents easily occur.Moreover, at this time, due to heavy physical exertion, people are very tired, and their hands and feet are not usually flexible and easy to accidents. I hope that riders must pay attention to safety. Generally speaking, you can ride with a level 6 headwind, and you should consider taking a rest if you have a level 8 headwind.When cycling downhill and downwind:Downhill and downwind are the most comfortable enjoyment in a bicycle trip. At this time, the fatigue of the uphill has already been thrown away. Sometimes it is not necessary to kick a foot, but a few kilometers in a row. However, you must pay special attention to safety when you encounter steep slopes, bends, uneven ground, or the possibility of sudden escaping of vehicles and pedestrians.At this time, the brake should be tightened from the top of the slope, so as not to be caught off guard, at least the brake should be the underside. When encountering a steep slope, even if the road is wide and flat at first glance, be careful. I have encountered two situations.1. There may be small rocks on the road, and you can't see them at first. When you see it, it is too late to avoid it. At this time, the speed is very fast and sharp turns are more dangerous.2. When the bicycle came down the mountain, a crosswind suddenly blew across the mountain. The bicycle was fluttering from side to side at high speed, which was difficult to control. I hope that riders will be alert to this situation. Always check the brake pads. If the brake is defective, adjust or replace the brake pads in time. Don't wait until you fall down to know what you are afraid of. I hope that new riders on the road will not "keep their wisdom after a short period of time".
Judging from the current trend, there is no doubt that larger brake discs can give you more braking power. Under the same other conditions, you only need to increase the size of the disc brake discs. More braking force. This is because the larger disc allows the brake to obtain a larger brake arm or brake radius.Generally speaking, 140mm and 160mm discs are mostly used in road bike brakes. 160mm discs have stronger braking force, can better cope with certain situations, and can also ensure the best braking effect. In addition, a larger disc heat dissipation area is also larger, which can further improve the overall performance of the brake. The 140mm disc is the most aesthetic standard, but if many riders weigh more than 80kg, the braking force of 140mm discs is not enough for them, so you can use the front 160mm rear 140mm configuration, the overall center of the brake is The front brake is more dependent on the braking force of the front brake. If the rear wheel is relatively strong and the rear wheel locks and slips, it is not a good thing. Therefore, it is also a feasible solution to configure the rear wheel with 140 discs with weaker braking force. Weight reduction of the whole bike.The mountain bike takes into account the need for more braking power, and the tires can also provide more grip, so the disc size generally starts at 160mm. The current mainstream trend is that on XC mountain bikes, the front wheels use larger 180mm or even 203mm (200mm) discs to further improve braking power. On the heavier downhill or enduro, 200 or 203mm discs are generally used on the front and rear wheels. (The current mainstream mountain bike disc thickness is 1.8mm)But larger discs also bring some additional problems. For example, a faster line speed will speed up the wear and carbonization of the disc, and a larger diameter will reduce the rigidity of the disc. Under strong braking, the disc will experience jitter problems.
Today, let's take a look at what knowledge you need to know when choosing cycling pants, and how you can be a professional and fashionable biker.The importance of cycling pantsFor friends who are always clamoring about "cycling butt pain", in addition to changing a comfortable cushion, the best way is to wear a pair of suitable cycling pants.Generally speaking, cycling pants are tight-fitting, and a layer of sponge pad is sewn into the crotch. In addition to absorbing sweat and reducing wind resistance, it also reduces hip damage and improves riding comfort.The functions of cycling pants are as follows:• Wrap the leg muscles to reduce the energy lost by muscle shaking during exercise.• Reduce vibration, can ensure that it does not slide back and forth on the seat, and reduce energy loss.• Protect the perineum area but remember to choose a sponge pad. The silicone pad is hot and easy to hip bone.The material of the cycling pants is convenient to drain the sweat from the body to the outside and keep the skin dry.The inner thigh of the cycling pants and the part in contact with the seat bag are made of special materials, which can avoid friction between the upper tube and the inner thigh during bending.The bib cycling pants do not tie the waist, which can ensure the strength of the core muscle group while ensuring smooth abdominal breathing. If possible, you should try to buy bib cycling pants.How to choose cycling pants?Choosing cycling pants is very important. Picking the good ones will get twice the result with half the effort, and picking the ones that are not suitable for you can only be counterproductive.• Choose good qualityJust like buying clothes and shoes, cycling pants also pay attention to material and quality, at least to make them "value for money." Generally speaking, the mainstream materials of cycling pants are POLYESTER, POLYAMIDE, SPANDEX, and COOLMAX. Choose according to your own budget. It can be breathable and quick to dry.• Choose the right sizeIn addition to the material, everyone should also consider the size when choosing cycling pants.Cycling pants must be worn with the right size and elasticity. This will not only fix the cushion in the right position, and help your butt avoid torture, but also relieve muscle fatigue, reduce wind resistance, and move more easily. Oolong with trouser legs rolled into the chainring appeared.• Best reflectiveGenerally speaking, good cycling pants must have three major protective properties, the material is comfortable, the other is elastic enough for self-cultivation, and the third is reflective, which is especially important for night riding enthusiasts!Reflective cycling clothes and cycling pants can refract the light, giving a certain warning to nearby drivers, cyclists, and passers-by to prevent accidents due to being invisible.Something elseCycling pants are a good thing, but if you choose the wrong one or use it improperly, it is easy to backfire. One of the first is the cleaning of cycling pants.The trouser pads of cycling pants are easy to breed bacteria, so pay attention to cleaning and disinfection after each wearing. In order to avoid distortion of cycling pants, it is recommended that you wash them by hand. After washing, wring out the water by hand and let it dry. Never use a washing machine to spin dry.In addition, everyone knows the importance of sun protection when riding in summer. Many people have such thoughts, "I don't need sunscreen on my thighs if I wear pants anyway"?In fact, except for the expensive cycling pants, most of them use a coating on the surface of the fabric to resist ultraviolet rays, and this function will be weakened by continuous washing.When the sun is shining in the summer, go out for a ride. Don't be too troublesome and put on sunscreen all over your body~When wearing cycling pants, try to avoid the following:1. Wear underwear and cycling pants, which are very unfriendly to the ass.2. Wear silicone cycling pants. Although silica gel is a good material for shock absorption, it is not suitable for areas with more apocrine glands.3. Think of compression pants as cycling pants. Isn't the cycling pants just for the cushion?4. Buy cycling pants with waist rope, even elastic bands are much better than cycling pants with waist rope.5. The saddle is not adjusted properly, too high, too low, or level.
1. Body energyTo truly have good endurance, you need to use most of the energy reserves in your body.There is glycogen (carbohydrates) in the muscle and liver, glucose in the blood, triglycerides (fat) in muscle, and the largest energy reserve: body fat.This energy is your fuel tank to keep riding a bike. Excessive lactic acid or lack of oxygen supply will stop you. Conversely, when you run out of glycogen in your muscles, low liver glycogen or low blood sugar levels are the reason why you stop in the attack.2. Increase carbohydrate intakeIncreasing your endurance requires eating carbohydrate food every three hours one to two days before long-distance cycling, and drinking plenty of water to digest food.These carbohydrates can help store glycogen in your muscles, but only for these few days, you are only cycling lightly. If you are going to ride the bike a short, intense ride, not full of glycogen will make you feel better.3. Eat breakfast early before cyclingEven if your glycogen reserves are sufficient, you cannot guarantee maximum endurance. You need to eat breakfast early before cycling and eat a breakfast rich in carbohydrates, protein, and fat 2-3 hours before departure.If you eat too late, it will reduce rather than increase your endurance. Or, drink a carbohydrate-rich drink an hour before your departure.4. Maintain supplies during cyclingThe goal is to keep 200 to 400 calories of liquid or solid food (tested during training before the official ride) in the stomach.If you are convinced that you are at a high level, you can ride faster at the beginning, but you need to recharge every 20 minutes. Or, you will crash after 1 or 2 lack of supplies. The goal is to consume approximately 60 grams of carbohydrates per hour of cycling.Researchers in the United States explained that in a 64-kilometer ride, consuming 15 grams of honey or glucose per 16 kilometers can improve the riding level compared to drinking only water.Riders who maintain high glucose and low honey glucose can get home 2.75 minutes earlier. Compared with riders who only drink water, they have an average of 40W higher power output in the last 16 kilometers.If you find that you often crash late during cycling, and cycling is just drinking water, then this research is very useful for you.5. Train your physical enduranceMake your body really ready. Carry out regular riding in advance to ensure that your body can better use fat reserves, In this way, the rider can use more fat and effectively preserve carbohydrate reserves.You need to do 4-6 hours of aerobic cycling every week and not eat breakfast for 2 hours to ensure that you use the body fat.In conclusion:The most important thing to improve cycling endurance is to eat, eat, and eat. Eat a lot of carbohydrates 1-2 days before long-distance riding, eat 2-3 hours in advance on the day of cycling, and eat constantly during cycling.Of course, daily training must deliberately adapt the body to use fat as fuel, rather than precious glycogen reserves. As long as you pay attention to supplies, everyone can ride a bike a long distance.

The function of bicycle helmets to protect the lives of cyclists is beyond doubt. According to the report of the American Highway Safety Insurance Research: 98% of the deaths from cycling in the United States in 1999 did not wear a helmet, and those wearing helmets in collision accidents reduced their risk of serious head injuries by 85%. Not only does the helmet feel cool, but it's also really cool, at the same time, the ventilation holes on the helmet can make the head feel cooler. As an old saying goes, a clear head is easier to win the game.The principle of helmet protection for the head is that the person wearing the helmet can make the hit head stop relatively slowly. If the person without the helmet hits the head on the ground, the brain will swell and cause hemorrhage. The convergent spherical shape in the helmet Objects can absorb the impact and avoid these unfortunate events.Choosing a helmet that suits you can make you more handsome. What is suitable for you? Take the helmet with the rim of your forehead at the center of your forehead. The helmet will not circle around your head, and will not move around The shaking will not have the feeling of clamping, but it will protect your head easily and naturally. Naturally, the breathability cannot be ignored. The more pores, the better the breathability, but under the premise of ensuring safety, this is not a consistent rule, because some helmets do not have many vents, but the air permeability can be achieved in the design.Helmets are the first equipment to ensure human safety, so the helmets of regular manufacturers will have corresponding standard certification marks, such as the American Society for Testing and Materials (ASTM) or Snell Foundation, and there is usually some international, national or regional authoritative certification agencies Certification mark.It's right to choose a lightweight, sturdy, and breathable helmet. It has large vents and good ventilation. It has an alloy frame inside and is reliable in strength. It has a COOLMAX lining and is comfortable to wear. Some helmets have insect-proof nets on the front. , Is a very considerate design.[Texture] Helmets are generally made of foamed materials (ordinary or high-density, the difference between the two is its anti-collision effect) and has a smooth shell surface;[Weight] The thing that presses on the head should not be too heavy, which is why the riding helmet does not use alloy materials;[Inner lining] is the part of the helmet that is in contact with the head. It can improve the wearing comfort at ordinary times and produce a cushioning effect when the head is hit. A well-made helmet has a large inner lining coverage, better texture, and a stronger bond with the inside of the helmet;[Wearing Comfort] It is mainly due to the personal feeling of weight, lining, straps, and head circumference. Wearing a comfortable helmet can greatly reduce the pressure on the rider's head and neck and maximize the impact on the rider. Improve the protection effect;[Breathability] The long-term airtight state of the head will have a bad effect on the scalp and make the rider feel uncomfortable. Therefore, a good helmet has more holes or a larger hole area, which is to improve the breathability;[Wind resistance effect] The helmet puts the human hair in the helmet, which reduces the wind resistance of the head. For those who are keen to increase speed, the influence of the helmet shape on the wind resistance is also worthy of attention.[Types of bicycle helmets] Half helmet bicycle helmets are divided into road-specific (no brim), road bike and mountain bike dual-use (with detachable brim), etc. Some friends also use helmets similar to those used for baseball or roller skating. Full-face cycling helmets are similar in shape to motorcycle helmets and are generally used by speed or climbing bike enthusiasts.
Regarding the service life and maintenance of the chain, I believe many cyclists will have questions, so we have compiled a simple Q&A to teach you how to judge the life of the chain and how to maintain it in normal times. Let's take a look.Q: How often should I change my chain?A: Take the Shimano 10/11 speed chain as an example. The original manufacturer recommends replacing the chain every two to three thousand kilometers. If the chain is still not stretched after this mileage, it is recommended to check it with a chain gauge every month thereafter. It can be replaced after stretching over 0.5mm.Q: If you don't want to change the chain so frequently, can it be used up to 10,000 kilometers?A: Of course, the chain is not so unbearable, but if you continue to use it after exceeding the recommended mileage, it may cause the cassette to accelerate wear and reduce the speed change performance.If you change the chain every two to three thousand kilometers, you can also extend the life of the cassette. Almost all the original cassettes can be used for 10,000 kilometers and then eliminated. However, if a chain is used for six to seven thousand kilometers and then replaced, it may be as result, the cassette is excessively worn. At this time, even if the chain is replaced with a new chain, the cassette may not be able to bite the chain and cause the chain to skip teeth.Q: How do I usually maintain the chain?A: If you don't often ride in a humid and muddy environment, you can generally use dry chain oil, oiling every two to three hundred kilometers, and make sure that every chain is lubricated. After oiling, remember to Wipe off excessive chain oil.If you must often ride in the rain or muddy environment, it is recommended to use wet chain oil. Because wet chain oil is more likely to be contaminated with dust, it is recommended to clean the chain before oiling it every time to be effective. Let the chain oil lubricate to the chain, and the frequency of oiling can be compared with dry chain oil.Q: Can I use WD-40 lubricant instead of chain oil?A: WD-40 is used for rust removal, and only 15% of the ingredients are mineral oil for lubrication. Besides that, it does not have any lubrication function, which is of no real help to the chain that needs to operate for a long time.But now WD-40 also has special maintenance products for bicycles, which also contain chain oil, so don't use WD-40 to lubricate your chain.
People often experience cramps when cycling. What exactly is cramping? Cramps are actually muscle spasms, which refer to the involuntary and strong contraction of muscles in a certain part of the body and the inability to relax quickly. The cramps most commonly occur on the back of the calf, the back of the thigh, and the front of the thigh. In addition, cramps may occur in small muscles including feet, fingers, arms, abdomen, and even between ribs.When cramping, the entire muscle becomes hard, and sometimes you can even see muscle twitching under the skin. The muscle cramps may disappear after a few seconds, or they may last for more than 15 minutes. If the original exercise is not handled in time or is interrupted, it may happen repeatedly in a short time.The real cause of cramps during exercise has not been determined so far, but it is generally believed that it is caused by many factors affecting each other. We have summarized some of the causes and treatments of leg cramps during cycling, and hope that the majority of riders should pay attention to protect themselves during the ride.Common causes of leg crampsInsufficient stretching and warm-up exercises before cycling;When rocking the bike, the action range is too large, and too much, the muscles are overstretched, which causes the accumulation of local acid metabolites and the blood supply is not smooth.Sudden changes in ambient temperatures, such as temperature, or jumping directly into cold water, excessively cause the leg to twitchLong-distance cycling for a long time loses too much salt without being replenished in time, and the body's electrolyte balance is brokenInappropriate cycling postures, such as the saddle angle is not adjusted properly, too low or too high, will burden the knees or the muscles of the upper and lower legs, especially if you maintain a posture or a gear ratio (gear) for a long time. Make the muscles tired, so you should adjust the cycling posture in time to relieve the fatigue of some muscles.Fatigue, sleep, lack of rest, or excessive rest lead to the accumulation of local acid metabolites, which can cause muscle cramps. For example, walking or exercising for too long, causing excessive fatigue of the lower limbs or insufficient rest and sleep can cause lactic acid to accumulate; too much rest for too much sleep, blood circulation slows down, and carbon dioxide accumulation.Emergency treatment of cramps during cyclingImmediately use non-twitching hands and feet to control the bike to stop on the side of the road, and shout for help from the riderLeave the bike, support the body with one foot in a half-squat state, stretch the cramped foot, and the rider will help him break his foot and press his leg.After the twitches are relieved, do some muscle stretching massages appropriately.If there are riders who bring hot water, they can use a bicycle towel to apply heat, which can also relieve the pain caused by convulsions.
