Regardless of whether it is the first bike or the Nth bike, before the start, I will hesitate to assemble a bicycle, hoping to achieve the 100 points in my mind. Let us simply analyze the characteristics of buying a complete bike and assembling a bicycle to help you consume fewer brain cells.Unless you have a tool wall, know the specifications and compatibility of various parts, and have special channels to get cheap parts, it will not be cheap to buy parts separately. If you are newer, you will buy a lot of strange or wrong things, easy to spend wrong money.Compared with buying a complete bike the advantages of assembling the bicycle:Freely decide what grade of parts to be equipped on the bike;Freely decide what purpose the bicycle will be used for;The complete bike can only be exchanged for different models according to different purposes. It is not as free as assembling a bicycle, and the reality may be cruelerThe paint you like does not have the function you want,Have the features you want but don't have the paint you like,The paint you like plus the features you want, but it doesn't have the size you wantAssembling a bike requires a lot of time to search for parts, and after finding them, they will have to assemble them one by one, and buy a new one in case the specifications are wrong. It is also a way to pay the bicycle shop to assemble the bike, but it also takes time and also requires an assembly fee. But it's faster than the time it takes to explore. Inexperienced users may damage the parts by themselves. At this time, it is best to find a professional to help you assemble the bike. Buying the complete bike only needs to spend time looking for the bike, and the rest is handled by the professional technicians of the store, which will save a lot of time overall.A sense of accomplishment: Of course, it is more than buying a complete bike! Seeing his bike taking shape step by step, the sense of accomplishment is indescribable! That feeling is the same as seeing a child raised all the way finally grow up and have a successful career.Skills: If cycling is an important activity in your life, it is best to learn how to assemble a bicycle by yourself, and prepare some equipment for long-term use. If you learn how to build a bicycle, you can better maintain your bike. When you encounter problems during cycling, you can find out and know how to solve them in time. At the same time, when you buy the next bicycle, you can quickly assemble it. When you have your own channels, you can save more money than buying the whole bike!Click Here to buy Carbon Fiber Full Suspension MTB Frame
Cyclists need to improve the three main elements of speed, strength, and endurance: training content, nutritional supplies, and equipment. Here to share with you, the coup disassembly of upgrading equipment.1. Lighter wheelsThe first thing to upgrade is the wheels. why? Everything comes from the rules of physics, and the rolling weight has a greater impact than the static weight (frame). This means that only a few hundred grams of weight loss can dramatically increase the speed. You will speed up on flat roads and throw away riders, and you will be more powerful when climbing hills. You will especially feel the importance of lightweight wheels.2. Aerodynamic wheelsAnother way to increase speed is aerodynamic wheels. Many wind tunnel test results have shown that when the speed exceeds 40 kilometers per hour, the aero wheel can save 1-2% of pedaling output. The reason is very simple. The higher the frame height, the more aerodynamic wheels can reduce turbulence and reduce air resistance in headwinds. However, although it runs fast, it is also more difficult to control than the low-frame high-wheelset, so it is recommended to use it in the time trial.3. TiresIn theory, the closest contact between a bicycle and the ground will have a great impact on rolling speed and comfort. However, people don’t care very much and just use standard tires when buying a bicycle. This is very wrong. Our suggestion is to try high-weave-density road tires. A tire with a high TPI number means that the higher the fine nylon thread is woven inside, it can reduce the rolling resistance and increase the speed. But there are advantages and disadvantages; the disadvantage is that high TPI numbers are more prone to snake bites. When winter comes, change to winter tires with thicker rubber layers.4. Derailleur kitThe electronic kit can be said to be a major evolution in the evolution of bicycles in recent years. When the traditional mechanical kit is still pulling the cord, the electronic kit has sent electronic signals to the front and rear derailleur, which is a wireless signal near the speed of light. Among the many benefits, the most important is more precise and quick gear shifting.5. BB bottom bracketIf you use a poor-quality BB bottom bracket, your large plate crankset will not rotate smoothly and save effort, so you will waste some energy when you step on each lap. It is recommended that top players who pursue performance choose BB bottom brackets with ceramic bearings for two reasons, both of which are critical: the first is that ceramic bearings will reduce resistance; the second is that their life span is more than ten times that of steel bearings.6. Power meterThe function of the computer should not only display basic information such as speed and RPM. If you care about your pedaling performance, the power meter is already an indispensable helper. The power meter can actually measure the wattage of the power generated by the rider on the bicycle, and then transmit this information to your bicycle watch mounted on the handle.Why are these power data so useful? Because when you have the FTP functional threshold power (Functional Threshold Power)-that is, the data of the maximum average power obtained in an hour of exhausting and stable riding, you can match your physical lactic acid threshold Ride in the interval. This is very helpful for the sprint high-intensity (121%-150 FTP) in the first interval (about 55% FTP) and the sixth interval.
Cycling is a great activity that can help you stay fit and lose weight. But how much time is appropriate for cycling each day?Riding for 30 minutes three to four times a week can help accelerate your weight loss and significantly improve your fitness levels. 30 minutes of moderate-intensity cycling 4 times a week can burn about 1.3 kg of fat per month.30 Minutes to Bike and Lose Weight The average person burns about 400 to 700 calories riding a bicycle for half an hour under average riding conditions. In order to lose 1 pound of fat, you need to burn 3600 calories, which is equivalent to 5 to 7 hours of moderate cycling. Riding more than 3 or 4 times a week can be challenging for beginners. It is recommended that you start with fewer rides and slowly increase the intensity as your knees and joints adapt. How far can you ride in 30 minutes? Most new cyclists can cover 8-10km in 30 minutes. Ride at an average speed of 19-26 km/h on a flat road. As the weather and terrain change, so will the average speed and distance traveled. If you’re cycling in the city, you also need to consider traffic. The following factors can affect your speed, in order of importance: your fitness level terrain headwind or crosswind bike type tire width and pressureHow Fast Does Your Performance Improve After 30 Minutes of Ride? Unfit individuals may feel the need to take a break after riding for 10-15 minutes. If you fall into this category, there is no shame in it, and no need to panic or throw in the towel prematurely. If you can only ride 10-15 minutes without a break at first, and you ride the bike 2-3 times a week, within three weeks you’ll be able to ride 30 minutes without any problem. Your fitness level will increase exponentially in the beginning. After a month of regular cycling, you’ll feel energized and fit enough even on moderately difficult climbs, and you’ll also notice a big boost to your health in other areas (such as when climbing stairs and not out of breath). How often should you ride？ You should start out cycling 2-4 times a week depending on your current fitness level. Riding less than twice a week won’t get your muscles going enough, and starting out more than 4 times a week will initially take its toll on your body too much. Remember that a new rider’s muscles and joints need time to get used to riding and they need time to recover. Experts recommend 30 minutes of cardiovascular exercise at least five times a week to maintain a healthy lifestyle. So cycle 5 times a week, and of course, any combination of cycling, running, and walking. The most important thing is to find something you enjoy doing and something that keeps you fit, and cycling is definitely a good choice.
1. Healthy breathing theoryThere is a lot of knowledge about breathing, and it is not so easy to discuss and study it. Different sports have different breathing characteristics. And some good breathing methods also need to be developed. Why focus on breathing? The combination of man and nature is here! I don’t understand qigong, but don’t talk about anything when you lose your energy. The same two people eat the same food, why is one tired after running 10 kilometers, while the other is still running for hundreds of kilometers? The reason is here, the efficiency of energy conversion is inseparable from breathing!To put it simply, only a sufficient oxygen supply can guarantee the most thorough material oxidation and energy release! The energy for muscle movement comes from the ATP substances stored in the muscles, but the amount of ATP is quite small, only enough to provide consumption for about 8 seconds. When it is used up, the blood sugar will be converted into ATP to supply the muscles Use, but there is a problem here, whether the oxygen is sufficient or not, if the oxygen is not enough, a large amount of blood sugar will only produce a relatively small amount of ATP (there are other ways to convert it into ATP). , a large amount of oxygen brought by a reasonable breathing method is especially important for us to ride to the summit. In addition, what is inhaled is irritating to the alveoli. Air pollution, dust, bacteria, and more can take a toll on your lungs. A runny nose is also a classic symptom of a respiratory infection. When you ride against the wind, the cold air goes straight down the respiratory tract and lung cavity, which has some reactions to the respiratory tract. Consider breathing through the nose. Don't make a big mouth, just open a small mouth. Nose hair and nasal cavity can filter the air and warm the air. This way the airways will not be irritated.2. Cycling breathing experience Breathing is just as important when it comes to cycling. In the past, I liked to ride fast when I first came up. After a certain distance, I was prone to abdominal pain. Later, I came to the conclusion that it was caused by breathing, and part of the outside air entered and mixed with the stomach. So for a while, I paid special attention to breathing with my stomach instead of my chest, and the result was much better. It is right to breathe through your mouth when riding, especially when you climb a hill, if you think about it, you can do it without your mouth. But Zhiqiu is not asking everyone to take a big breath of cold air immediately after eating breakfast, but to tell friends that if you ride on a flat road, normal nasal breathing can satisfy you, so you don’t need to take a big breath. Moreover, the mouth breathing I am referring to on a flat road is carried out under the premise that the mouth and nose are down, avoiding the limelight, and the abdomen is automatically contracted. When going uphill, you need to take a big mouthful of oxygen, and use your mouth and nose as much as possible (it’s a waste if you don’t use it). If it’s cold, it’s recommended to warm up your body before going out. It is enough to open the mouth naturally, and the tongue can be rolled up properly, which helps to heat the gas.3.Some "death ride" alpine symptoms will disrupt your normal breathing rhythm Climbing to a height of 4,000 meters is a normal phenomenon with red and swollen throats, swollen tonsils, and dizziness. The reason is simple: the air is thin, and breathing is needed to supply oxygen to the blood. At this time, under the necessary night drug conditioning, it is very effective to apply some Vaseline oil in the nasal cavity during the day.
Carbon fiber is something that bicycle riders love and hate. Carbon fiber bicycles have a noble name and a high price. However, they also have unknown aspects, such as being unrecyclable and environmentally unfriendly, and easier to break compared to metal frames. So what about the carbon fiber bike?The high price of carbon fiber bikes means that their glamorous appearance is not used to show off. In some aspects, the characteristics of carbon fiber are indeed more suitable for cycling than metal, such as lightweight and various ratios, as shown below:Of course, carbon fiber materials are also inferior. It can be seen that the weight-to-rigidity ratio of the materials in the picture is almost the same under the same mechanism. Even lighter carbon fiber materials are inevitably lost in rigidity to heavier metal frames, so the lightweight rigidity of the frame is not good. This of course is negative. The designers of the frame usually do some tricks on the structure, such as adopting a design that increases the pipe diameter and reduces the wall thickness to allow the power transmission area of the carbon bike frame. It is more rigid, which is also common on many metal frames, which can reduce weight and increase rigidity. This is also the reason why many metal frames have relatively large pipe diameters.Of course, there are disadvantages to this point. For example, aluminum alloy pipes will have problems in welding when they are drawn to a certain degree of thinness, and carbon fiber is the same. When it is thin to a certain degree, it will produce the opposite effect.Take a look at this carbon fiber cloth, it looks like a tuft of plastic cloth. Many riders will find out why this material does not have that kind of carbon fiber pattern. Like this one below.It turns out that the former is a single-direction carbon fiber cloth, and the latter is a real carbon fiber cloth. The K value of the woven carbon fiber indicates the number of carbon filaments in each bundle of carbon fiber. Of course, the bigger the better, because this is related to the production cost.It's like seeing the strength of carbon fiber only in the longitudinal direction of the fiber, so we have to weave these fibers horizontally and vertically. After layers of weaving, the strength of the carbon fiber material will gradually appear.Regarding the numerous numbers of carbon fiber, we can only "look at it", so how strong are the numerous models? This picture can be displayed very well. Inside, T and M are carbon fiber materials with two different characteristics.The production of carbon fiber frames is not as simple as rolling carbon fiber cloth into tubes and connecting them. Each manufacturer has its own characteristics for the production of carbon fiber tubes and frames. The manufacturing of the frame is very technical, which is why the carbon frame produced by the cheap foundry is quite different from the regular brand carbon fiber frame.So when buying a carbon fiber frame, please choose a regular brand frame, such as Trifox, click here to buy Trifox road frames and mountain bike frames
1. Lightweight and high rigidity. At present, the weight of high-end carbon fiber bicycles is generally lower than that of aluminum alloy and titanium alloy frames, and the rigidity is very large, which improves the pedaling efficiency of the rider and saves physical strength.2. Good fatigue resistance. The carbon fiber frame has super fatigue resistance, and the fatigue resistance test can reach more than 1 million times. Everyone knows a term: metal fatigue, any metal that has been used for a long time will have it.3. Good shock resistance and strong impact resistance. Vibration tests on beams of the same shape and size show that it takes 9 seconds for the aluminum alloy beam to stop vibration, while the carbon fiber composite beam only takes 2.5 seconds. The good damping of the composite material reduces the turbulence of the bicycle and improves the rider’s cycling comfort. Related tests show that the qualified carbon fiber composite material bicycle is 8 times that of the ordinary bicycle.4. Anti-corrosion. Compared with traditional metal frames, carbon fiber composite bicycles have unquestionable environmental resistance, acid, alkali, and industrial atmosphere, good performance, and no rust.
In winter, we often have to face the snow-covered ground and mountain roads, but this will certainly not stop enthusiasts from riding enthusiasm. There are some snow riding tips for cycling enthusiasts, unless you have the kind of snowmobile with particularly exaggerated tires, these tips must be useful to you.Adjust your mentality: First of all, you must realize that snow riding is much more difficult and slower than ordinary riding, especially when climbing a slope, you may need to go back and forth to go up the mountain smoothly. The best thing to do is to focus on the feet, your goal is to move forward a little bit, don’t rush it.Replace the appropriate pedals: Even if it snows heavily, many friends still ride bicycles. In the snow, you need to repeat the action of getting on and off the bike frequently. In this case, it is more convenient to use non-locking pedals. First of all, the flat pedals without locks are more convenient for clearing snow, and it also allows you to choose thicker winter boots. This is not only good for keeping your feet warm but also will not cause headaches like walking in locked shoes when you need to carry out many activities. . It is very important to know that it is very important to keep your feet warm in severe cold. Lower the tire pressure: You can control the tire pressure of your tires. If you ride in the snow for a long time, you can release more air. If it is the kind of road that is completely covered with snow, reduce the tire pressure to the lowest level. This applies to those friends who don’t have a special snowmobile, a little difference can produce two different results for riding and pushing. Smaller gears for better cadence: Riding in the snow usually means you don’t do aggressive moves like sprints and jumps. The suggestion is to choose a small gear ratio, sit well on the saddle, and maintain a relatively comfortable high cadence so that you can ride for a long time.Prepare for mountain climbing: On snowy roads, the riding conditions are usually more complicated, and only a small part of many routes are suitable for rushing downhill. Mountain climbing in the snow is a very special experience, and of course, there will be some special skills. It is recommended to control the center of gravity of the body reasonably. If the snow shell is relatively hard, the center of gravity of the body should be moved forward, so as not to damage the surface of the snow. If the snow is soft, the center of gravity of the body should be moved backward, so as to gain better power. In a word: true knowledge comes from practice!
If you want to buy a new bicycle, there are many factors that affect your choices, such as price, features, riding style, brand factors, and even painting.Sometimes the choice boils down to the choice of frame material. There are four common frame materials: steel, aluminum, titanium, and carbon fiber. Materials can affect riding and usage, so you need to know the key differences between different materials.Everything you need to know before buying a new bike. For many people, material selection is as important as accessories and prices, and different materials are suitable for different types of cycling. The frame will be the core of the new car, taking up the main budget, you need to choose wisely.The following analyzes the key characteristics of each material to help you make the right choice.1. AluminumAluminum is the most common material for road bikes, offering a more affordable price. It is also an ideal material for the frame, which can make rigid and lightweight frames. The aluminum frame has been treated unfairly for a long time, such as the cycling feels rough and uncomfortable.WHY BUY ONE: Within your budget, you want a light and hard frame for competition, or you want the best bike at the same price.2. SteelMany years ago, steel was the only frame material. Nowadays, steel frames still exist, which can provide smooth cycling, which is why touring bikes still prefer to use them. But steel will not be used in large-scale manufacturers now. In fact, it is easy to process, so it is often used by manual custom manufacturers. If you want to customize, steel is a good choice.WHY BUY ONE: If you don’t care about its weight, want a custom frame, and you like the smooth cycling quality3. TitaniumTitanium is a very satisfying material. It is comfortable and has a certain shock absorption capacity. At the same time, it is lighter than steel, stronger than aluminum, and will not rust. In fact, its surface can maintain gloss for a long time. But after so many years, titanium frames are still very expensive.Titanium can make high-performance racing bicycles, but can also be designed for long-distance cycling, providing very good comfort.Most titanium uses 3AL-2.5V (representing 3% aluminum and 2.5% vanadium) and 6AL-4V, which is the hardest grade of titanium and can be seen on many expensive frames. Because of its hardness, it is difficult to process 6AL-4V into seamless tubes. For example, rear derailleur hangers and head tubes are often cut.WHY BUY ONE: You want a long-life bike that is light and has smooth cycling.4. Carbon FiberFor many riders, they will not choose other materials except carbon fiber, which is the mainstream in the cycling racing world. Among these four materials, carbon fiber is the lightest and hardest, and it is also very expensive. However, the price of carbon fiber frames has dropped significantly in recent years.Carbon fiber is a very flexible material, giving designers a lot of room to play, and the shape of the tube is not restricted, for example, it can make an aero road bike.Carbon bike frames are completely different. There is a huge difference between cheap and expensive carbon frames. Different carbon fiber materials, different processing methods, and different factories will all have a big impact. Carbon fiber is relatively easy to design and control, allowing the frame to achieve a balance between various characteristics, even lightweight, comfortable, and rigidity.WHY BUY ONE: If you want the lightest and hardest road bike, or the aero bike, you have enough money to buy it.
The knee is the most vulnerable part of the body during exercise. Cyclists know that if the seat height is not adjusted correctly while riding, long-term riding will cause knee pain.Other sports are the same. Protecting the knee is a prerequisite for sports. About the knee, you must know that these knee joints cannot be repaired.In the traditional concept, mountain climbing and stairs are good aerobic exercises, which can help us exercise the muscles of the thigh and buttocks. At the same time, it can exercise our heart and lung functions.But many famous orthopedic experts reminded me: climbing stairs and mountains is the "stupidest sport."Climbing stairs or climbing a mountain is a weight-bearing exercise, and the joints below the waist must bear the weight of your body, especially the knees. When the body climbs up the steps, the weight on the knees will instantly increase to about 4 times the usual.Take a person weighing 60 kg as an example: when walking on a flat road, each knee bears 60 kg. When climbing stairs or mountains, the knee load instantly becomes 240 kg, which is equivalent to carrying a piano on each knee. Moreover, the faster the speed, the greater the pressure on the knee.Besides, this kind of wear on the knees is irreparable! If the wear is too severe, only the joint can be replaced!The life span of the knee joint is only 60 yearsOn the one hand, we need to exercise the muscles of the thighs and buttocks. But on the other hand, we can’t hurt the knee joint as the price.Because the lifespan of the knee joint is determined by genes, most of which are 60 years, overuse will aggravate its wear and tear, and it cannot be repaired.But experts explained that it is not difficult to solve this problem. We only need to change our exercise habits to extend the life of the knee joint:1. Don't run or skip rope on hard concreteStrenuous exercise on hard ground, such as squatting, leaping, running, and skipping rope, will increase the wear on the kneecap. Especially when you squat down and then stand up, the wear on the joints is greatest.Articular cartilage is about 1 to 2 millimeters in length, and its role is to cushion pressure and protect bones from rupture. If you have to exercise on a hard floor and bounce back under the super reaction force, it will cause considerable damage to the joints and bones. It is recommended to exercise in the rubber sports field.2. Reduce climbing, climbing, and other sports after 50 years of ageWhen climbing mountains and stairs, the knee joints will be under pressure 3 to 4 times more than their body weight.Especially after the age of 50, people’s knee joints will be somewhat worn out. At this time, such exercises should be reduced. For some friends who have suffered knee joint injuries after the age of 40, pay special attention.Orthopedic experts said: Climbing stairs or climbing mountains does have many advantages such as enhancing cardiopulmonary function and burning calories, but the disadvantages are also great, so the gains outweigh the losses. It can be replaced with a walk.The most suitable exercise for the knee joint: swimming, cyclingFor ordinary people, the most beneficial exercise for joints is swimming. In water, the human body is parallel to the ground, and all joints are basically load-bearing.People with chronic diseases such as diabetes and high blood pressure swim more, which is good for the whole body. In order to achieve the purpose of physical exercise, you can choose swimming, cycling, gymnastics, and other light-bearing exercises.(Buy the most comfortable mountain bike or road bike)Knee rehabilitation: the most suitable exercise methodWhether you have knee discomfort or not, this exercise will suit you. Because of this exercise: no need to go out, no equipment, no damage to the knee, and exercise to the knee!1. Find a chair that can be backed, sit with your hips back, and lean against the back of the chair. Put your hands behind the chair and cushion your back.2. Put a bath towel under the thigh. You can also bundle several bath towels and towels together, as long as they are thick enough and tied firmly, the purpose is to raise the knees.3, sit upright, back straight, feet hanging down, and sway naturally in tandem. Don’t need to swing too much, just shake it easily!This trick seems very simple, but it is very helpful for strengthening the knee.People with old knee injuries or foot pain can use a healthy foot to drive the painful foot. The healthy foot supports the painful foot while shaking back and forth naturally. This is equivalent to rehabilitation and can gradually restore the knee to health.
