The first is the problem of brake fluid. If different brands use different brake fluids, the seals used will be quite different. For example, the brakes using DOT oil and the brakes using mineral oil are different in the selection of seals. There is a big difference because the DOT requires a stronger corrosion resistance of the seal.The second reason is the hydraulic ratio. if the piston area of your brake lever is fixed, then if the piston area of the caliper you replace is larger, you must consider whether the capacity of your brake lever piston can drive a larger caliper.For example, if the brake lever corresponds to a two-piston caliper, replacing the four-piston caliper with a larger diameter and area at this time may cause the problem of excessive stroke. The reverse is also the same. If the caliper area used is smaller, the brake lever stroke may be too short. This will directly affect the linear performance and braking strength of the brake design.
People who want to lose weight through exercise will ask: "Is it possible to lose weight after exercise?" and "How come it seems that the more you exercise, the more fat you get?"Simply put, if you want to lose weight, the necessary condition is that the calories you consume are greater than the calories you take, and if you want to consume more calories, you rely on exercise. But why do many people feel that the effect of exercise to lose weight is not obvious? Zhang Peirong, a nutritionist who also loves cycling and running sports, said that most of the calories consumed by exercise are often not as many as we think; but the calories eaten are more than expected! Therefore, the key to weight loss is diet control, and the influence of exercise is second.Does appetite improve after exercise?Most people eat more after exercising. There may be two situations. One is an exercise to a certain level and consumes a lot of calories. Naturally, they will feel hungry and want to eat; the other is to compensate for their mentality. I felt that I could comfort myself, so I ate more food.But is it really hungry, or just thought it was hungry? Zhang Peirong believes that you must quantify your calorie intake and consumption to have a basis, not just by feeling!In summary, exercise is the help you lose weight, and the desire to eat is the resistance to weight loss. Whether you can lose weight depends on whether it helps you or the resistance. Therefore, some people lose weight after exercise, and some people lose weight after exercise! If you want to lose weight effectively and healthily, you must increase your calorie consumption and control your calorie intake.Control your diet and pay attention to caloriesEspecially for people who do not exercise regularly, they may regard cleaning or shopping, this type of "activity" as "exercise." Or go for a walk outdoors, walk a few laps on the playground, and sweat as if you have exercised, but in fact, it is only caused by the hot weather. Even sports such as cycling for 10 kilometers and running for 3 kilometers may actually consume less than 200 calories.When the intensity is insufficient and the time is not long, so the calorie consumption is not much, the mentality is often compensated by eating more.Therefore, after exercise, try to choose low-calorie and satiety foods so as not to exceed your calorie intake! Especially at this time, muscles need to supplement a lot of glycogen and protein to repair tissues. Therefore, the diet should be mainly carbohydrate food, with the appropriate amount of protein, such as sandwiches, sweet potatoes, steamed bread, toast, etc., and a small amount of meat, one piece Tea eggs, soy milk, low-fat milk are fine.Increase strength and increase consumptionIf you want to increase the calorie consumption of exercise, you must increase the time and intensity of exercise! Many people think that sweating means enough intensity and exercise, but in fact, sweating is not a good indicator, it is often just because of the hot weather. It is recommended that you exercise for at least half an hour, which is also a big advantage of cycling, which can maintain a longer exercise time in an aerobic state. Secondly, the intensity of exercise should be enough, whether it is to walk, jog or ride a bicycle, to reach a moderate intensity, the easiest way is to measure the heart rate, which is about 130 or so; if you don't have a heart rate monitor, let yourself feel a little breathless during exercise. , You can talk, but there is no way to continuously talk and sing intensity, which can effectively increase calorie consumption.Eating less and getting more exercise is the only way to lose weight and lose weight.Increase basal metabolic rateOf course, many people are worried that with the control of diet, when calorie intake decreases, the body's basal metabolic rate also decreases. This is correct. The body has a protective mechanism. When our body feels a crisis when the calorie intake is reduced, it will automatically enter the "energy-saving mode" to reduce the basal metabolic rate. In addition to weight loss, the basal metabolic rate will also Follow the decline, it will enter the so-called stagnation period for weight loss.If you don't want your metabolic rate to drop, you must train your muscles. In addition to aerobic exercise, you must also add weight training to increase your body's muscle mass, which will naturally increase your basal metabolic rate and calorie consumption.The conclusion is that if you want to lose weight and lose weight, eating less and hyperactivity are still the same rules, and neither is indispensable.
First of all, pay attention to your brake feel in daily use, especially after the oil change, if the brake is significantly softer and the stroke becomes longer, it may be that the air in the caliper piston has not been removed. If this is the case, If it is relatively mild, it will generally return to normal after a period of use. If this is the case for a long time, you must consider re-exhausting. If your residence has a vacuum lubricator with hydraulic brakes, it is recommended to replace it for better exhaust. Empty the air in the caliper.The other thing is to check for excessive wear of the film. Under normal circumstances, as the film becomes thinner with the use of the caliper, the piston of the caliper will protrude more, and real-time maintenance will ensure a reasonable gap between the film and the disc. This is also a major part of the open oil circuit. Advantage. But when you change the oil, the piston on the caliper will be completely pushed into the caliper due to the block, so if you continue to use the old pad and install it directly on the bike, the brake stroke may be too long, Although you can squeeze the brake a little bit by letting in to make the pad gap smaller and improve the brake lever stroke, the best way is to replace a new pair of pads.Generally speaking, it must be replaced when the wear of any one side reaches 2/3. The wear of the film is not completely horizontal. In many cases, the wear is inclined, so the wear 2/3 should be the thinnest. The place prevails. At this time, replacement is very necessary. Continued use may damage your caliper.If your brakes have been used normally, but suddenly start to soften within a few days, the stroke becomes longer, and the brake dead spots are blurred or even disappear, then check whether there is an oil leak. Generally speaking, oil leakage will appear in the brake lever piston part, and some will appear around the caliper piston. If it appears in the piston part of the brake lever, basically just replace the new piston seal to solve the problem.The oil leakage at the caliper is first eliminated to eliminate the problem of excessive exposure of the piston caused by the excessive wear of the film, and then the Y-shaped sealing ring around the piston should be replaced, or the entire caliper can be replaced directly.Other problems such as weak brakes, obvious dead spots, but unable to stop. If the brakes have problems such as howling, you can basically replace the pads directly. These conditions are usually caused by oil stains on the discs during wiping, transportation, or even rain. The best solution is to replace the new disc and thoroughly clean the disc.
Today I will talk to you about some anxiety about cycling. Of course, you may not have anxiety here, but if you are cycling, it is possible to encounter a few anxieties.1. Anxiety about lack of moneyMost riders don't have much money, and they also need to go to work to make money to support their families. Ever since the bike was brought in, the equipment was bought, the bike was upgraded, accommodation, registration fee, and dinner together… just like this, the wallet is getting thinner and thinner every day. Once you set foot on the way to riding a bike, the wallet is no longer in control!2. Bike crash anxietyI spent so much money on buying a bike, and I didn't pay enough attention to fall it once. The cost was too high, so I usually ride it carefully and lend it to others. It's a nightmare… Every time I ride out to play, I fall into pits and mountain roads. I'm afraid it gets hurt.Seeing other people crashing or crashing yourself will feel that riding is too dangerous, but after a while, I want to ride a bike again, always moving forward in entanglement.3. Trust anxietyI bought a bicycle secretly and did not dare to tell my family. I was afraid of being scolded by my parents, saying that riding a bicycle is very dangerous, and riding a bicycle will affect learning. Can riding a bicycle be a meal? I'm also afraid that my wife will not support it. Anyway, all kinds of incomprehension, all kinds of worry.4. Lost bike anxietyI bought a bike I like, and it's all news among my friends around me, but while enjoying this satisfaction, every time I see others lose their bikes, I can't wait to see if my bike is safe.The bike must be more careful and cherish the new bike within your sight, and you can't wait to tie it together. Even if the bike has been locked with two big locks, plus GPS anti-theft positioning, but I still can't make sure that when I ride out, I'm not sure about parking…5. Anxiety of not being able to ride a bikeRiding a bike is addictive. If you don't ride for a day, you will feel uneasy. I always feel that something is missing! After riding, I think about where to ride next time. Business trips and bad weather will make you worry about whether you can ride a bike!6. Seeing that riders don't wear helmets are also anxiousIt's not just myself, but seeing the riders around me riding without a helmet makes me anxious for others.They think that just riding by the river, in the park, or commuting to and from get off work, in general, are the roads they are most familiar with. There is no need to wear a helmet. In fact, it is very dangerous to go on the road without wearing a helmet. Wearing a helmet while riding a bicycle can protect you at least when you crash.
Today, I will talk about ways to improve cycling comfort and speed without "spending much money".1, SaddleA large part of the uncomfortable and uncomfortable cycling can be attributed to the seat saddle. Therefore, most brands offer saddles of various shapes, sizes, and lengths.Many bicycle shops now have multiple brands of saddles, maybe you can try the one that suits you best!About 20 years ago, Specialized first introduced Body Geometry technology to make the cushions have different widths, the purpose of which is to ensure that the seat bones are properly supported to prevent numbness and general discomfort. Whether it is comfortable or not, try more to know! In addition to the width and shape, many riders find that the uncomfortable solution is only to have a groove in the middle of the cushion to relieve pressure. For example, Trifox's CS100 comfortable carbon bike saddle & seat.2, cycling pantsSince there are so many different kinds of cycling pants, the padding in cycling pants should be a uniform standard, but the fact is just the opposite!A few years ago, Endura launched the FS260-Pro SL, with three different pad widths to choose from to suit different riders. Further, relieve the discomfort of the hips.Following the trend, Fizik also introduced a series of cycling pants designed to fit with the saddle. They use different shapes of pad design, and different fabrics and fabric shapes.3, the width of the handlebarIn fact, in the vehicle parameters of road bikes, the width, range, and shape of the handlebars are very different, which also has a deep impact on cycling. Usually, we choose a handlebar that matches the shoulder width.From the classical handle, the small curved handle, the ergonomic handle, their reach or sink amount are different.The key to selection is:Width:Too wide has large wind resistance, and too narrow is not conducive to control. Generally speaking, you can choose shoulder width, but make some adjustments according to personal preferences.Features of suitable bicycle:Road bikes are suitable for curved handlebars, and ergonomic handlebars for a modern frame can complement each other.4, The stemFeel your handlebar is too far? Can't stand your waist? Even a sore wrist? The culprit may be a stem of inappropriate length, whether it is too short or too long.There are many specifications of the stem, and there are many variables from one person to another, but there will only be standard stems on the whole bike, and there is no possibility of optional, so you need to understand what kind of angle and length are Best for you. Trifox's X12 carbon fiber road frame offers 90mm, 100mm, and 110mm stems, you can buy them according to your needs. A too-long stem may make your posture lean more forward, although there is a little aerodynamic advantage, your waist may protest earlier!5, lock pieceIf you are a rider who uses lock pedals, then you must pay attention, the correct and perfect installation of the lock plate will help you get the best riding condition!Even if the position of the lock plate slightly deviates, it can easily cause discomfort, reducing efficiency and power output. The two key factors for setting the cleat are the angle and the front and rear position.Put on the lock shoes, mark the positions of your first and fifth metatarsals on both sides of the shoes, and then draw two parallel lines on the soles, as long as the position of the locking pedal is placed between the two parallel lines.The angle problem is due to the fact that different people's feet may be outside or inside, and more should be normal.The lock plate of the outer eight-character should be rotated inward, and the lock plate of the inner eight-character should be rotated outward.6, cycling suitsThe easiest way to get a speed bonus is to wear tight clothing. Loose and flowing clothes will only increase wind resistance, on the contrary, tight clothing can significantly reduce resistance.Cycling is fast and the time is short, so we can go home early to wash and sleep!7, helmetNowadays, road helmets with aerodynamic characteristics are beginning to be sought after, and choices are gradually increasing. Compared with conventional helmets, they can effectively reduce wind resistance without sacrificing ventilation.8. WheelsA large amount of wind data shows that carbon wheels do have more aerodynamic advantages than aluminum wheels. Here we recommend Trifox's carbon fiber wheels. Depth has 40mm, 45mm, 50mm, and 60mm with a width of 25mm, and there are also quick-release and barrel axle options. There is always one that meets your needs.
The era of disc brake road bikes has officially arrived, and there are more and more road bikes using disc brake systems. At present, disc brake road bikes use hydraulic systems as the mainstream, but for road bikers, hydraulic systems can be said to be A completely new system. When you plan to join the ranks of disc brake road bikes, do you have a clear understanding of the characteristics of the hydraulic disc brake system?The most common maintenance action of the hydraulic disc brake system is to replace the new oil and remove the air in the oil circuit. Because the fault tolerance rate of the hydraulic system is low, every action during maintenance must be quite focused. The oil change and maintenance actions of hydraulic disc brakes require the use of a variety of special tools and skilled operations. It is recommended that the oil change and maintenance work be carried out by a professional and trusted bike shop to ensure the hydraulic disc brake system of your bike. You can operate with peace of mind!Preparation toolsThe following tools are mostly used when performing oil change-related actions. Since the bike body needs to be able to adjust the angle flexibly, it is recommended to use a professional repair rack to fix it. In addition, if you want to install and adjust the tubing, you also need to prepare tubing cutting and oil needle installation tools.From left: open-end wrench, Shimano special mineral brake fluid, oil injection syringe, flat screwdriver, oil cup, oil cup adapter, piston stop, and oil cup stopper.Start preparation for an oil change1. Before the oil change action, please be sure to remove the wheelset and the brake pads first, because there may be oil leakage during the oil change action or even accidental splashing. If oil contaminates the brake discs on the wheel or the brake pads, the braking ability will be greatly reduced or invalid. Therefore, please pay attention to keeping the brake discs and the brake pads away from any oil.A. First remove the anti-loosening buckle on the fixing bolt of the reaming plate.B. Use a flat-head screwdriver to remove the fixing boltsC. At this time, the film can be pulled up directly, don't lose the elastic film in itD. Insert the piston stopper and use it to fix the piece fixing bolts.E. Sometimes the piston is pushed out because of the loss of the film. When you want to push back the piston, do not apply force at a single point. Use a flat object larger than the piston to push back to avoid damage to the piston due to excessive pressure.2. Pump the new Shimano special mineral oil into the syringe, and the amount of oil drawn in needs to be more than the demand of the oil circuit; remove the dust cover of the oil injection hole, and put the syringe on the oil injection hole. When installing the oil injection syringe to the brake caliper, please remove the air in the syringe first to prevent air from entering the oil circuit and causing the brake function to fail.Because the gas has extremely high compressibility, when there is air in the oil circuit, it will absorb the thrust when pulling the brake lever, which will cause the caliper end to operate poorly or even fail to operate.A. When pumping new oil, it is necessary to prepare a quantity that is higher than the demand, so as to avoid insufficient oil injection and cause air intake in the oil circuit. After the oil injection is completed, put the extra oil back.B. Before connecting the oil circuit, make sure that the air has been completely discharged from the syringe and pipeline to avoid injecting air into the oil.C. Remove the dust cover of the oil filling hole.D. Put the oil pipe of the oil injection syringe on the oil injection hole.3.Open the cover of the brake lever, remove the oil hole bolts, and connect the Shimano special oil cup and the special oil cup adapter for the road bike oil disc brake lever. Before removing the oil hole bolt, adjust the angle of the bike body to the level of the oil hole of the brake lever to avoid oil leakage when the oil cup is installed and unloaded. When installing and removing the oil hole bolt, be careful not to lose the O-ring on the bolt to avoid oil leakage or air intake.A. The oil cup must be installed horizontally.B. The adapter seat prevents the installation of the oil cup from being disturbed by the shape of the brake lever.C. The bolts, oil cups, and adapters all have a leak-proof O-ring. Be careful not to lose them.4. Adjust the bike body to fit the oil filling angle. Each Shimano brake lever has a different position of the built-in oil pot, so there will be a different demand angle. In order to make the oil circuit push smoothly when changing the oil, and allow the air in the pipe to be discharged smoothly.5. Remove the stopper on the oil cup, loosen the caliper oil filling hole screw about 1/8 turn, at this time the oil circuit becomes open, slowly push the oil injection syringe connected to the caliper end to push the new oil into the oil circuit. The replacement of brake oil is not to inject new oil after leaking old oil but to directly inject new oil to push out the old oil. In order to remove the air that may remain in the oil adjustment pipe while filling, new oil needs to be injected from the lower end of the brake caliper.A. Remove the oil cup stopperB. Loosen the caliper oil hole screw about 1/8 turn.6. When the color of the oil introduced from the brake lever oil cup is lighter (the color of the brake fluid will become darker after a period of use), and there is no more air in the oil cup, it means that the brake fluid has been completed. replace. Tighten the oil filling hole screw at the end of the caliper.A. Observe the color difference of the oil coming out of the oil cup to judge whether the new oil has filled the oil circuitB. Tighten the caliper oil filling hole screw.7. Press the brake lever to confirm whether the oil path is full and without air, because the caliper piston has been fixed by the piston stopper, if the oil path is full, the brake lever should only have a movable stroke of about 5mm; if the brake lever stroke is too large, the hand feels soft. There may be air in the oil circuit, the exhaust action should be performed again, or the oil filling action should be re-operated.8. If it is confirmed that the brake lever is operating normally, please insert the stop bolt into the oil cup at the end of the brake lever, adjust the body to the level of the oil hole of the brake lever, remove the oil cap and the adapter seat, and lock the oil return hole bolt. Brake levers and calipers can use 50% isopropyl alcohol to clean the brake fluid that leaks during operation.A. Remember to insert the stopper when removing the oil cup, otherwise, the oil will flow everywhere.B. Lock back the oil hole bolt of the brake lever.C. Isopropyl alcohol can be used to clean the oil-contaminated area.9. After cleaning is complete, remove the piston stop on the brake caliper, and install the receptacle, so that the anti-loosening buckle on the fixing screw of the film must also be installed. After installing the wheelset, confirm that the brake can work normally, and the oil change of the hydraulic disc brake is completed.A. The existence of the anti-loose buckle is often forgotten because of its small size.B. Also remember to cover the dust cap of the oil filling holeAfter reading the oil change procedures for hydraulic disc brakes above, do you think that disc brakes on road bikes are super troublesome? In fact, the editor has also simplified a lot of detailed actions… But in order to get the sharp braking performance of hydraulic disc brakes with the better operation, I believe all this is worth it! As for the maintenance of the oil circuit that will get messy and may fall short, let yourself go and leave it to a professional bike shop to complete it.
There are usually two types of lock shoes, mountain bike lock shoes, and road bike lock shoes. What are the advantages and disadvantages of each? How to choose?Mountain bike lock shoes, like mountain bikes, have strong terrain adaptability, mountain lock shoes were designed for use in various harsh environments, such as rainy mud, gravel roads, and so on.One of the advantages of mountain bike lock shoes is that they are durable and adaptable to the environment/terrain.Compared with the durability of mountain bike lock shoes, road lock shoes have many limitations. For example, a road bike is suitable for riding on good pavement. If you wear a road bike lock shoe and run over a larger stone, the shoes will probably have problems.One of the more common methods of model selection is that you have to buy a road bike with lock pedals and road bike lock shoes for road bikes, and buy mountain bike lock pedals and mountain bike lock shoes for mountain bikes.This is basically not wrong, but everyone has a different purpose for riding a bicycle, and the use environment for locking shoes is also different, so there is another use environment selection method besides the model selection method.Because of the problem of the sole structure of the mountain bike lock shoes, walking is also very smooth when not riding, such as getting off the bike to buy water, ending the bike ride and climbing the stairs, etc., getting off the bike to take pictures when seeing the beautiful scenery.After the road bike lock shoes are installed with the cleats, it is not only inconvenient to walk, but also easy to cause the cleats to wear.In addition, the advantage of mountain bike lock shoes is that it is easier to lock and unlock (than road lock shoes), which is also a design that takes into account the complexity of the terrain.Speaking of this, it seems to be talking about the advantages of mountain bike lock shoes and the disadvantages of road bike lock shoes. What are the advantages of road bike lock shoes compared to mountain bike lock shoes?If the advantage of mountain bike lock shoes is breadth (lower limit/adaptability), then the advantage of road lock shoes is height (upper limit/professionalism).Road bikes are biased towards speed and races, so road bike lock shoes are better in terms of lightweight, pedaling efficiency, comfort, and ability to match a power meter.Lightweight means that the mountain bike lock shoes of the same design will be naturally heavier than the road bike lock shoes. This is because the mountain bike lock shoes have more studs on the soles (increasing grip);Pedal efficiency means less energy loss;Comfort refers to the same long-distance (high-intensity) riding, road bike lock shoes are less prone to foot pain (in fact, it is related to the lock plate);Power meter refers to that there are not many power meters for mountain bike shoes.Even with the configuration, mountain bike shoes are heavier than road bike shoes because the soles have more studs and the circles in the pictureSeeing this, you should understand.If you are mostly cycling, you often stop to take pictures after riding, the experience of mountain bike locking shoes will be better.If you like speed, race, and more training, road bike lock shoes are more suitable for you.
Now more and more people in the streets and alleys fall in love with road bikes. Novices or especially mountain bike riders before are used to disc brakes. Two fingers can break it easily, so many bikers often complain. Road bikes are difficult to break, difficult to corner, and afraid to go downhill. Then let everyone know the correct turning posture.The quality of cornering technology is related to your personal safety and racing performance, and the most common cause of bicycle collisions is poor cornering technology. If there are a lot of corners in the race route, improving cornering skills will help maintain your position in the main group, as shown in the figure:There are three ways to corner:Co-incline: If you don't consider the situation of the corner, co-incline cornering is usually the most common cornering technique for novices. This method of cornering is most suitable for corners and large arcs, dry roads, and cleanliness. In the United States and some countries, cyclists and cyclists ride on the right, and when turning left, the most efficient way to turn is when making a turn; while in countries that drive on the left, turning on the same turn is the most efficient way to turn. The first choice when transferring. When using the same tilt to the corner, just put the center of gravity on the outer pedal, and at the same time tilt the bicycle and body toward the corner. If the curve is wide enough and the arc is large enough, pedaling can be continued when cornering.Tilt outward: Novices rarely use this turning method, but when the curve is narrow, such as turning right when driving on the right or turning left when driving on the left, this turning method is very useful. The camber method is more suitable for curves with larger curvature than the same-incline corner method.This is the same technique as Countersteering for riding a motorcycle. When using this technique to turn into a curve, you must stop pedaling, because when you take an outward leaning, the body leans more than the same. When cornering, the inner pedal is on and the body's center of gravity is placed on the outer pedal. The next action may feel a bit counterintuitive: the arm on the inside of the curve is straightened, and the elbow on the outside of the curve is curved.In fact, your current action is to make the bicycle roll, and doing so will break the gyro effect when the wheel is turning. (Annotation: The gyro effect means that the wheel is like a gyro, which helps the cyclist when it turns quickly. Keep your balance, the faster the speed, the more obvious the effect will be. When the wheel turns quickly, the resistance to turning the handle will increase, and cornering will be more difficult), allowing you to tilt the bicycle sharply while keeping your body upright Turning into the curve, you can go through a curve with a lot of curvatures. When using camber to the corner, the speed must be maintained above 24 kilometers per hour to be effective. Therefore, it takes more practice to get used to this way of cornering.Tilt inward: When the road is slippery or with sand or pebbles, you should use an inward inclination to corner the bend. Whether you want to turn right or left, you have to slow down. If the radius of the curve is very narrow, such as when cycling to the right in the United States, you must stop pedaling. This is done so that you can safely go through the corner without crashing. The correct cycling method is to only lean the upper body into the curve when cornering, while the bicycle stays upright and keeps the knees close to the upper tube position-that is, the knees do not point towards the curve.Other considerations when cornering: If the road is wet and slippery, reduce tire pressure by 25%. This has little effect on the overall speed, but it can increase the friction of the tire when cornering. The tires used when cornering is also important. Tubular tires have round tire walls, so they are more suitable for cornering than open tires with flat tire walls. The painted road surface becomes very slippery when wet. Cycling on such a road is like riding on ice, so be careful when cornering. The same is true if there are round hole covers on the road, the wet round hole covers will also become more slippery. If the road is slippery, be careful when cornering on a small slope. Before cornering, use the brakes to slow down, but do not use the brakes when cornering!
Carbon fiber not only has the inherent characteristics of carbon materials but also has the soft processability of textile fibers. Its specific gravity is less than 1/4 of steel, but its strength is very strong. And its corrosion resistance is outstanding, it is a new generation of reinforcing fiber. Carbon fiber is widely used in civil, military, construction, aerospace, and super sports car fields.Carbon Frame advantagesThe carbon fiber frame is characterized by "lightweight, good rigidity, and good impact absorption". The carbon fiber frame has advantages that other materials do not have. It can manufacture lightweight bicycles of about 8 or 9kg. This carbon fiber lightweight bicycle best reflects its advantages when climbing a hill, smooth and refreshing when climbing. Unlike some light aluminum alloy frames, it feels like a kind of pullback when climbing a hill.(1) A lightweight frame can be madeThe carbon fiber frame is made by layering carbon fibers against the direction in which stress occurs to obtain strength. The carbon fiber frame is very light, which is due to its density and strong tensile strength.(2) Good shock absorptionCarbon fiber is used to make artificial legs for the disabled when exercising, or special springs are used in various fields. Make use of its excellent shock absorption performance to make bicycles without shock absorbers.(3) Frames of various shapes can be manufacturedThe basic forming method of carbon fiber is to spread a fiber sheet on a mold and then pour into the resin and burn it. Can be made into various shapes of the frame.Carbon Frame disadvantages(1) Complicated stress calculationThe carbon fiber frame is composed of carbon fiber, which is characterized by strong tensile strength but weak shear strength. Complex stress calculations (longitudinal rigidity and lateral rigidity) are required during processing, and the carbon fiber sheets are overlapped and formed according to the calculation. The processing technology varies from manufacturer to manufacturer, and it is important to choose products from experienced and reliable manufacturers.(2) Difficult to change the sizeIt is difficult to change the size due to the molding after the mold is made. Cannot respond to orders of multiple sizes and styles.(3) AgingWill the resin age because of this? This is an existing issue, it will gradually whiten when placed in the sun. Of course, this phenomenon is related to the manufacturer's technology. It is best not to place it in the sun.Species of carbonFull carbonAll carbon fiber bicycle accessories are made of carbon fiber materials.Half carbonMany bicycles are made of aluminum alloy and carbon fiber. For example, a frame may be made of carbon for the upper tube and aluminum alloy for other parts (or carbon for the rear triangle…), the front fork arm is made of carbon fiber, and the front fork tube is made of aluminum alloy. This can be said to be semi-carbon.Carbon-coatedSome accessories such as frames, handlebars, stems, cranks, front forks, eatposts, etc., are made by manufacturers of aluminum alloy, and then a layer of carbon cloth is covered on the surface, which is what is covered with carbon.Note:Carbon fiber contains resin, so it can be said to be acid-resistant. However, for carbon fiber, internal factors should be considered. It uses resin, so the possibility of resin aging exists. Carbon fiber bicycles should be kept away from sunlight when not in use, as sunlight and ambient temperature have the greatest impact on them.
