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.
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.
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.
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 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.
