As the cycling team continues to grow, the technical level of riders is also constantly being pulled apart. How to better and quickly integrate into the cycling team has become a problem that plagues novices. There are many people who like cycling, and they all come from different fields and have received different levels of education. Everyone has completely different personalities and habits. Although most riders are very friendly, you still need to pay attention to the following points when getting along： 1.don't ask others to borrow a bike This is a big taboo among cyclists. Everyone's bike is like their own sweetheart. Borrowing a bike is not a problem. The problem is that you accidentally crashed the bike while riding it. Do you think the other party will ask you to pay for it? How much compensation is appropriate? 2.Do not impose your own thoughts on others Everyone has different preferences for bike, just like some people like SRAM and some people like Shimano, the different feel also attracts different fans. This is not only for beginner riders, some riders who have been riding for a period of time also often do this kind of thing. In fact, this is nothing in itself, but some people like to add oil and vinegar, for example, your accessories are more expensive, your matching is unreasonable, Merida is not as good as Giant, etc. What you like and what you think is good does not represent the other party’s thoughts, so not imposing your own thoughts on others is the most basic respect. 3.Only ride a bike but don't care about life Cycling friends first met because of riding a bicycle. When someone rides with you, it doesn’t mean that they will tell you everything about him. Therefore, even if you have a particularly good relationship with a cycling friend, don’t ask others about their lives. Distance produces beauty, which is useful everywhere. 4.Don’t keep thinking about rushing to the front Some riders who have just participated in cycling may not be good at understanding the situation of the cycling team, so they are easy to rush to the front of the team on a whim. But in fact, in cycling, experienced riders are often at the front and rear of the team. For group travel, the allocation of personnel needs to be adjusted according to the situation of the team, not to show individual physical fitness. 5.not bad debts Generally, everyone is on the AA system for going out. Occasionally, I will meet some people who are happier than anyone else when eating, eat more than anyone else, and can always slip away when it is time to pay the bill. 6.follow traffic rules You don’t even care about your own safety, and you may even threaten the safety of others. Who would want to ride with such a rider? Running traffic lights, riding side-by-side, and speeding through crowded roads are all very offensive. 7.Teamwork Every group has its own rules, if you must be a maverick in a group, then I don’t think any club is suitable for you. You can communicate any dissatisfaction, but it is your fault to spread negative energy 8.Learn some basic maintenance and repair methods For daily riding, we need to know some basic bicycle debugging and maintenance methods, such as brake adjustment, bicycle maintenance after rainy days, etc. Only by mastering some skills can we go out to ride with more peace of mind.
Why do professional bicycle riders shave their legs clean? Please don't laugh, because there is neither a specific historical reference nor objective scientific findings that can explain this habit of bicycle riders, so let's make some reasonable guesses.Answer 1: Shaving can form an aerodynamic advantageTheory:In this era of aerodynamics, seamless tights, aerodynamic frames, streamlined helmets, and ultra-light carbon wheels are all flying in the sky. Therefore, it is unreasonable to ignore the small but vital aerodynamic advantage of bare legs.Reality:The actual effect of shaving depends on the amount of hair on your legs. To be reasonable, take a look at the current tights, they really fit, and there are no seams and buttons. So, if all of this works, then too much hair on your legs may have an effect. ——Former professional bicycle rider Levi LeipheimerMaybe it's useful in the top time trial, but in the mountain bike, it is not useful. —— Jeremy Horgan-Kobelski, champion of the U.S. National Mountain Bike ChampionshipIn terms of aerodynamics, the actual effect is not great. But I know that if I look down at my hairy legs while cycling, I feel like I'm going to lose speed in an instant. ——Davis Phinney, Champion of the Tour de FranceAnswer 2: This is more comfortable and convenient during a massageTheory:During the massage, the leg hair will be torn off, a lot. (It hurts to think about it!!!)Reality:That's why I shaved my leg hair. If I didn't do this, I would be very hurt. ——Former professional bicycle rider Levi LeipheimerIf you have too much hair on your legs, you have to use a lot of oil. You don't want to be braised pork feet, do you? ——Tour de France champion Andy HampstenSimply, this is the number one reason why I shaved my leg hair. I can't imagine the pain of a full-body massage for a pair of hairy legs. At the same time, I also think that some good massage techniques do not require too much oil, so shaving is very important. ——Horgan-KobelskiShaving your leg hair may feel better, but from the perspective of deeper muscles, it makes no difference whether you shave or not. I work in the team all year round, and some professional players even shave their leg hair in winter. ——Chris Grauch, Certified Massage TherapistI bet that shaving the leg hair is for easy massage. Do you want to caress your hairy thighs? ——Todd Wells, champion of the U.S. National Highway and Cross Country CompetitionAnswer 3: Care for wounds is simpler and more effectiveTheory:When there is no leg hair, it is easier and faster to clean and bandage the abraded wound. The leg hair will be stained with dirt and bacteria will easily breed. Without leg hair, heal faster.Reality:I always think this is the main reason. When you fall off the bicycle, your skin is easily bruised. The hair on the legs will only get dirty, not conducive to bandaging. ——Davis PhinneyThe absence of leg hair also makes the intramuscular effect stick more firmly, and many riders have been using this recently. ——Horgan-KobelskiAnswer 4: This just looks cool-I can ride fasterTheory:Bodybuilding muscle lines look sharper, and leg hair affects the visual experience.Reality:In people's general concept, smooth legs seem to move faster. Before the TT game, I clean my legs. You can feel the gust of wind hitting your legs. (We are not as powerful as you, I can't feel it)——Chris Horner, RadioShack Team (the predecessor of Trek Team)Answer 5: Women like men with smooth thighs.Theory:In fact, we just want our partners to please us all the time.Reality:When my husband Jeremy (Horgan-Kobelski) no longer rides, I still want him to shave his leg hair. I think it looks too hot with full-leg hair, even though I am also a bicycle rider. Maybe most female compatriots are different from what I thought. ——Heather Irmiger, a professional mountain bike riderAnswer 6: This is a traditionTheory:Shaving your leg hair is an important sign that you are committed to pursuing lofty goals and working hard to manage your life. This means that you are a real racer. Furthermore, going to a team race with unruly hairy legs is like going to church in shorts.Reality:Shaving leg hair is the attitude a bicycle rider should have. ——Horgan-KobelskiTo me, this behavior is stupid. ——Leideville Time Trial Champion Dave WiensThis is a kind of fashion when I ride a bike. It’s also very Fashion now, real friends shave their leg hair. ——Phinney
Riders who have just started the lock pedal system, do feel quite troubled in how to operate and practice, what points should be paid attention to in the process of locking and unlocking? psychological factors In fact, riding with lock pedals is not as difficult as imagined. Most of them are caused by the psychological factors of zero-speed falls. Riders can first understand the working principle of the locking pedal, and thoroughly understand the principle of action between the buckle and the locking pedal. , to avoid frustration or falls caused by incorrect application of force. Loosen the tension value Novices can use the lock to adjust the tension value to the loosest state to practice first, and if possible, they can also practice with a training platform, which is safer and will not cause falls due to improper operation, and will be more psychologically at ease, will focus on the operation of the lock. If there is no training platform, you can also try to lean against the wall on one side, hold the brake with both hands, and practice the up-and-down lock. professional guidance Riders who have time and conditions can find senior riders or go to a familiar car shop, ask them for professional guidance, check whether their practice movements are correct, and ask them to give professional opinions and ways to improve, and these The pros show the right way and watch their pedal settings and riding position carefully. practice diligently Riders who have received the correct guidance already know the correct posture for getting up and down, then they need to train diligently on the correct road. After all, the master leads the door, and the practice is up to the individual. It is recommended that riders who are trying for the first time need to practice for 1-3 weeks. road experience When you have practiced to the point where you can lock up and down without looking at the pedals, it means that you have fully mastered and are familiar with the movements of locking up and down. You can choose a familiar and safe riding road for real road experience. Let your lock up and down state be in a state of natural response. early unlock After officially going on the road, it is recommended that beginners can pre-grab a long safe distance before each stop, and start unlocking early during this time. Don’t be so nervous, don’t be nervous when you can’t unlock it. Remember that when the crank is in a horizontal state, it is the easiest state to unlock. Don’t let yourself be in a panic, it will be even more difficult to unlock. Unlock with both feet When you have been able to unlock and lock naturally on the road, you can try to sit on the cushion and practice unlocking with both feet at the same time. If you need to stop for a short time when encountering traffic lights, it is recommended to unlock both feet at the same time, so that both feet can touch the ground at the same time. This will not only be safer but also allow your feet to stand and rest.
What is the difference between these road bikes? Which is right for you? In recent years, the market for road cycling has become broader, and its functions and gameplay have become increasingly segmented. You can use an enduro road bike for a short trip, you can also use an XC Road bike to challenge rugged mountain roads, and you can also choose a gravel road bike for a walk-and-go adventure. For now, as long as it is where you want to go, there is a suitable road bike for you to choose from.Although many people think that a gravel bike can do all the scenes mentioned above, in fact, on some roads, gravel bikes will make you feel unenthusiastic and dull. So what makes these three seemingly realistic road bikes have unusual uses and feelings? Let's take a look at the definition of these three types of road bikes or the scope of use.Gravel road bikeThe first is the gravel road bike. The Gravel road bike has a wide range of uses. It draws a lot of elements from the mountain bike, making this bike suitable for almost all road conditions. Not only can participate in the CX cross-country race within the scope of the rules but also can carry out long-distance adventure cycling, most suitable for high-speed riding on non-paved roads. This type of bicycle is generally equipped with a liftable seat tube, wider tires, and a single-disc or double-disc drive system suitable for more road conditions. We will explain in detail later in the different parts.Enduro road bikeThe enduro road bike used to be widely used, but it still limited some scenes compared to the later gravel. Although the frame geometry is similar to the gravel bike, both have a slack head tube, a smaller drop, and a wider shifting range, but for more complex road conditions, there are still big differences in handling and comfort.In order to make the enduro road bike more comfortable and reduce the fatigue caused by road vibration, many brands have considered more longitudinal compliance in the design of the frame.In recent years, with in-depth research on tire width, the entire industry is moving toward wider wheels and wider tires. In addition to the technology mentioned above, enduro bicycles generally have larger tire clearances, and most enduro bicycles have standard 28C tires, and in some cases wider tires.XC road bikeThe full name of XC is cyclocross. Because cross means X, it is abbreviated as XC. This type of race was originally designed to allow riders in cold Europe to participate in the race in winter. The XC competition is an all-weather type of competition, so you can often see the race on a muddy road under rain and snow. And there are various steps, sand, rocks, and tree roots on the track.The XC Road bike and the gravel road bike have a lot in common, but there are some differences in detail. In one sentence, XC is a more aggressive and aggressive gravel bike. Both bikes have versatility, comfort, and durability, but gravel is better.After understanding the concepts of the three types of bikes, let's take a look at their respective characteristics from the most basic and most different parts: the frame geometry.The geometric angle of enduro road bikeSince it is an enduro road bike, the rider's position must be more comfortable first. There is a saying that how far you can ride depends on how long you can stay on the bike, which explains the importance of comfort. Enduro road bikes generally have a longer wheelbase and a smaller reach, and the stack is also larger stack. This can be exchanged for a more upright cycling position. Although part of the aerodynamic performance is lost, it is more suitable for long-term cycling. The line is the gain lost.This geometric setting can prevent the rider from premature fatigue in the back, shoulders, neck, and legs during the long journey. Compared with the competitive road bike, some flexibility is reduced, because the longer wheelbase and slack head tube also prevent the small frame from overlapping toes so easily. (When turning, the front wheels will touch the toes.)In terms of drivetrain, the enduro road bike is more important than the other two bikes. The range of gear ratio is more compact, the tire clearance is compared with the competitive road bike, and the range of tire selection is also Larger can further improve comfort and smoothness, reduce road bumps, and let more vibration disappear in the tires instead of the rider's body.The geometric angle of the XC Road bikeCompared with enduro races and gravel, the XC Road bike has the two biggest differences. The geometrical angle of the head tube is slack (the angle is smaller), and the bottom bracket has greater ground clearance.These two characteristics are also extremely related to the game environment. The slack head tube angle can provide more stability when cycling with large drops and low speeds. Because the track environment of the XC race is extremely harsh, and the speed is difficult to compare with the road bike, handling at a low speed is very important.For the second feature, it is easy to understand that the bottom bracket has a larger ground clearance, which can better deal with obstacles on the road. In addition, the higher ground clearance also allows the rider to pedal when passing a curve without touching the ground. However, this will also make the rider's overall center of gravity higher, which in turn affects stability. Therefore, in the race, many riders will reduce the height of the seat by about 1cm to offset this change.In the final tire width, although there is a lot of space compared to the enduro race, if it is to participate in the UCI race, the tire width of the XC Road bike cannot exceed 33mm. At this point, gravel has more room to play.The geometric angle of gravel road bikeFirst of all, the purpose of gravel is to create more stability and comfort. Therefore, a longer wheelbase, a more slack head tube, and a lower bottom bracket ground clearance provide more stability for riding. The head tube is designed to be longer and taller, with a shorter stem, so that the rider's cycling posture is higher, so as to improve the comfort and vision in traveling and adventure cycling. The slack head tube angle makes the low-speed handling performance better, and will not appear as prone to "twitching" feeling like some performance-type racing road bikes.The design of the frame does not take the weight as the ultimate goal. It is also stronger than road bikes and increases durability. Functionally, if you want to take a walk-and-go trip, the extra mounting space on the frame is enough for you to carry the necessary equipment on the road. And basically, all gravel road bikes are equipped with fender mounting holes, and there are more bottle cage holes than the first two bikes. Especially the XC road bike, if it is a pure XC road bike, there is no bottle cage hole on the frame.If the first two still have part of the caliper, suspension brake, and other rim brake versions, gravel is basically the same disc brake design. Disc brakes make it easier for the frame to obtain wider tire clearances, and also provide braking performance on wet and muddy roads. Generally speaking, the width of gravel tires is more than 35mm, and individuals can reach more than 50mm. Wider tires have improved passability, comfort, grip, and stability. And individual models also support 700C and 650C wheels at the same time, and the playability is greatly improved.The drivetrain system is not so particular about the cadence, and more consideration of the usable range, mainly for the usability under low-speed cycling, so the gear ratio range is larger, although some pedaling efficiency under high-speed riding is sacrificed, for steep ramps and soft gravel roads provide more choices.So how should we choose?If you have seen this and don't know how to choose, I think you should first ask yourself: "What kind of road conditions do I ride on, and what kind of player do I belong to?"
Many riders have begun to waver, should they continue to ride in the snow and ice environment? How to ride a bicycle in snowy weather? What issues need attention? Check bicycle Before riding a bike in winter, it is very important to check the condition of the bike: whether the front and rear brakes are sensitive, whether the transmission can be used normally, and the snow on the tires should be removed as much as possible; and before riding a bike in winter, don’t forget to do some exercise Warm up, let your body move, and avoid joint injuries when cycling! Keep warm Be sure to keep warm when cycling in winter. The weather is cold, so you must be equipped with suitable riding equipment for snow riding, keep your head and ears warm, and wear gloves to keep your hands warm. If it is still snowing while riding, and the snow is relatively heavy, try to wear goggles. If not, then put the helmet on the brim of the hat and try to keep it as low as possible to avoid rain and snow from affecting your vision; Familiar with the road Cycling in winter should choose the road you are familiar with. In snowy days, the road is covered with snow, and it is difficult to distinguish the specific road conditions. Choosing the road conditions you are familiar with can make it easy for you to judge, knowing where there are potholes or where the water freezes, etc. It is best to make a judgment in advance and avoidance will greatly reduce the occurrence of injuries. If you can look at the snow on the tires, brakes, and flywheels when parking; Drive slowly When riding in ice and snow in winter, you must control the speed of the vehicle. It is advisable to control the speed of the vehicle not to exceed 20km/h. It is better to slow down when riding in a bend, and control the center of gravity to prevent the problem of sideslip. If you choose the way of shaking the car, it is easy to cause the center of gravity to slip and fall; when going downhill, you can control the center of gravity slightly backward, control the brakes, and use the rear brake as the main and the front brake as a supplement, and you must control the braking force. You can’t hug to death at once. Control strength Cycling in ice and snow weather in winter must control the riding intensity. In winter, you wear a lot of clothes, and the exercise consumption is relatively large under the same circumstances, so you should properly control the riding intensity and itinerary according to your physical fitness. And before departure, you must add some energy and heat, and finish riding early to avoid accidents in the dark. Focus Try to be highly concentrated when riding in winter. Note that the tire pressure should not be too high. If the tire pressure is too high on ice and snow roads, it is easy to skid and cause the car to crash. In cold weather, if the tire pressure is too high, it is easy to blow out. In addition, the lower the temperature, the smaller the friction between the ground and the tires. If you encounter ice, it is really bad! Don’t be brave Riding will increase the temperature of the body. If you ride with a load beyond your ability, it will easily lead to a lot of inflammation in the body, and the body’s resistance will decrease, causing soreness or unconsciousness, which will bring problems to the body. Then a cold and fever will affect the nervous system in severe cases. When necessary, you can go down to carry it out. It is not shameful to push the cart. Take care of your health. As the saying goes, practice in summer and practice in winter. Riders who like to ride outdoors should pay more attention to the weather conditions, plan their rides and keep warm. If the outdoor conditions are too harsh, don’t force yourself. You can choose The indoor way to ride or work out.
How to improve the body's anaerobic toleranceRoad riders need long-term stable power output. However, due to the diverse and constantly changing road conditions in our mountain bike races, mountain bikers often need a period of continuous high power output, and they often stop pedaling before and after this period of strong output. Or step on lightly to slow down, or pass obstacles.Therefore, the ability of a rider to repeat the high power output time and time again in mountain bike races is very important. Although aerobic exercise capacity is also very important here, if you can have both aerobic and anaerobic exercise capacity, you will have an absolute advantage.In the FasCat training camp, we asked mountain bikers to repeat short sprint training (anaerobic training). The content is to let the riders ride at their normal cadence for two to four minutes, and then use their maximum strength to stand and rock the bike for thirty seconds. After that, the cyclist returns to their normal cadence and enters the next cycle. Below we give an example of sprint training.Ride at normal speed for 9 minutes (if you have a power meter, it should be at 224-266 watts). At 3, 6, and 9 minutes, stand up and do a 10-second full sprint (357 watts). Repeat twice. Then return to the original state and continue riding for 9 minutes without sprinting.When the athlete's anaerobic tolerance increases, we can appropriately shorten the sprint gap, which is a higher intensity training. The following example:Slightly faster than normal, riding for 10 minutes (245-286 watts), standing up at 2, 4, 6, 8, and 10 minutes for a 15-second sprint. repeat three times. Then return to the original state and continue cycling for 10 minutes without sprinting.The most advanced training is to do sprint training during high-intensity cycling. That means sprinting when you are already cycling hard. In fact, such training is not done until two to three weeks before the race. Below is an example:Cycling vigorously for 20 minutes (268-310 watts), stand up at 5 minutes, 10 minutes, 15 minutes, and 20 minutes for a 15-second full sprint (357 watts), then return to the original state and continue cycling for 20 minutes Don't do sprints.This sprint training is more enough to stimulate our body to make corresponding adjustments to adapt to the intermittent vigorous output required in high-intensity cross-country.If you just want to improve your anaerobic tolerance, here is a tried and tested old method:Sprint at a high intensity (357 watts) for one minute, then return to your normal cadence and ride for one minute. Repeat this three times, and after sprinting for another minute, ride at normal cadence for 5 minutes. This training is done in two groups.This training has a total of 8 minutes (4 minutes per group, two groups) of anaerobic tolerance training. We can adjust the duration of each group according to individual differences, which can be between 5 minutes and 25 minutes. But do not repeat the sprint more than 7 times in each group. One minute per sprint is a good choice, but you can also adjust it to 30 seconds or 90 seconds.If you want to go to the next level this season, then this sprint training for mountain bike races is your secret weapon.The main reason that mountain bike requires such a strong sprint is the terrain. Rocks, tree roots, ruts, short and steep slopes, U-turns, and other obstacles will all require this powerful sprint to coordinate acceleration. So to overcome obstacles and maintain speed in mountain bike races, this sprint ability is necessary.The main difference in power required for mountain bike racing and road bike racing lies in these peak outputs. These short-term peaks will gradually accumulate into a huge physical demand. One or two times may not be a problem at all, but like in a game, 88 times in two hours will exhaust you.
Cycling outings are a romantic affair. Driving too fast, walking too slow, or only riding is a kind of enjoyment: you can see the infinite beauty of the scenery along the way. Autumn is the most suitable season for cycling, without the wet and rainy spring, the hot and dry summer, and the cold and windy winter. Everyone’s riding intentions are different, but I believe that everyone can get into a good mood through riding. Some riders seek lightning-fast speed and love the passion and sweat brought by speed; some riders ride leisurely, enjoying the scenery along the way and the mood of watching the scenery—just like a slogan, life is like For a trip, you don’t need to care about the destination, only care about the scenery along the way and the mood of seeing the scenery. Now, researchers have conducted the most significant study on the mental improvement of cycling, and the results are: Cycling ranks second in the mental improvement of exercise, second only to team sports. The researchers spent a year analyzing the effects of physical activity on the mental health of as many as 100,000 adults. Participants reported the type and amount of exercise they did throughout the study, as well as the number of days during the study period when they experienced negative emotional distress, such as sadness and depression. The data shows that people who insist on exercising only feel in a bad mood for 2 days in a month, while those who do not exercise feel in a bad mood for 3.4 days. The improvement in mood status was even more pronounced for people who were already depressed when they exercised: They had more than 3 fewer days in a month when they were in a bad mood. Of course, different exercises have different effects on improving emotional conditions. In a study of more than seventy sports, team sports came out on top for the best results: Basketball and other team sports had a 23 percent reduction in bad days, while cycling was a close second Since then, the number of days has decreased by 21%. The findings also suggest that team sports, in addition to the sport itself, also include social elements, and the benefits are more pronounced than individual sports. Therefore, the editor suggests that if you often feel in a bad mood, you might as well find three or four cycling friends and organize some cycling activities, which can effectively improve your bad mood, make you happier, and increase your sense of happiness.
First of all, the foot support bracket cannot pass the bike inspection in all competitions. Secondly, high-end bicycles are more concerned about weight, and you have to pay a lot of money for every gram of light. The last is to ensure the safety of cycling.Foot supports (parking brackets that come with bicycles) and mudguards (fenders) are dangerous equipment.The removal of foot supports and mud protection is generally for road bikes, mountain bikes, and other high-speed running and off-road bikes on abnormal roads. Bicycle foot brace and mud protection have their functions. A bicycle foot brace can facilitate the support of the bike. The mud protection can effectively prevent sewage and mud from being thrown on the body. However, these two pieces of equipment also have their disadvantages and safety risks.Disadvantages of bicycle foot support: bicycles supported by foot supports are not very reliable. You can observe it carefully. Usually, a strong wind blows on the road. Few bicycles supported by foot supports, even electric bicycles, and motorcycles, can still stand. Not fall. Then when the bicycle falls, it is very likely to damage the paint surface of the bike or damage some parts, or even make the parts scrap. Even if there is no wind, artificial scratching, and collision may dump your bicycle.The safety hazard of the bicycle foot brace: the foot brace is movable. The strong vibration of the bicycle on the bumpy road will easily make the foot support lower by itself, especially the loose foot support that has been used for a long time. In this way, when you turn sideways at high speed or when there are protrusions on the road, once the foot support is opened, the foot support can easily touch the ground and raise the rear wheel of your bicycle, causing the bicycle to lose control and crash.Therefore, I generally do not recommend riders install bicycle foot braces, especially riders who like high-speed cycling and off-road cycling. When parking, please tilt your bicycle down to the left. Note: It must be the left side, because there is a fragile rear derailleur on the right side of the bike, and the bike is placed down to the left so that you can pick up the bike and step up from the left side (there are not many left-handers, right?)! There are also friends equipped with disc brakes when you put your bike down to the left, pay attention to the disc not to hit the protrusions on the ground to prevent the disc from being deformed by external forces.About why mountain bikes are not equipped with mudguards, can check the article "Why are mountain bikes not equipped with mudguards?"
Senior cyclists should know that if you run hundreds of kilometers outside in a day, the mudguard is useless. The role of the mudguard is limited to the urban area. It slowly walks on the flat and clean road at a speed of more than ten kilometers per hour, and the muddy water carried by the wheels is also weak.Weak, thrown obediently on the fender without splashing on the bike body or human body. But if you participate in formal cycling activity, nature will be completely different:1. The cycling speed is faster than commuting riding, the slowest speed is also more than 15 kilometers per hour, and the average speed is about 20 kilometers per hour. The number and speed of dust and mud splashing have greatly increased. The shielding effectiveness of the mudguard will be reduced as a result. If you are in the city, the mudguard can cover block 90% of the splashes, but it may only be 60% in fast cycling conditions.2. The cycling time is very long, 5-10 times longer than the daily commuting riding time. The accumulated amount of dust, mud, and water has increased significantly. The daily commute cycling time is relatively low. Assuming that the splash accumulation per hour of cycling in the urban area is 1, then combined with the upper line, the splash accumulation will reach 4. If you ride for 5 hours, the dirt accumulation on the bike will reach 20.3. The burden of weight and volume (wind resistance) on physical strength increases: For example, if you carry a pound of objects for one kilometer, the energy consumed is 1KJ, which is very inconspicuous, right? But if you ride 100 kilometers at a higher speed (the wind resistance will increase), it's 150KJ, which is an order of magnitude number of is not easy to ignore.4. The mudguard itself also has the function of holding and carrying dirt, which will add extra weight. A bike without mudguards may only hold 50 splashes of dirt, but if it is a bike with mudguards, because of the increase in surface area, the dirt holding quantity may rise up to 55, or higher.5. When passing through mud, when the mud is caught between the wheel and the fender, it will greatly increase the cycling resistance or increase the probability of bicycle damage.6.When cycling on complex road conditions (such as forest roads), the mudguards will scratch or even entangle with the plants, and the completion of certain cycling actions will also be affected. In short, it is an obstacle.Finally, re-summarize the problem in plain language:1. The mudguard is basically ineffective in riding activities.2. The mudguard will increase energy consumption during cycling activities.3. will increase the probability of failure. Therefore, this type of mountain bike does not require mudguards. If the subject is only doing slow cycling on general roads, you can use a station wagon.4. The hidden safety hazards of mudguards: general mudguards are made thin and wide, and the materials are mostly steel, aluminum, plastic, resin, and other materials with a certain hardness. It's like a knife without a blade. In other words, it is a sharp protrusion on a bike. When the cyclist accidentally crashed, the kinetic energy is very large at this time. This sharp protrusion is very easy to cut your skin under the huge kinetic energy, especially in the summer when the riders wear very little and their bodies are exposed. The parts are many.
