In recent years, many young talents have died of cancer. Cancer has become the number one killer that seriously threatens the health of people all over the world. Many people are chanting campaigns to prevent cancer, but is there really an inevitable connection? Can exercise really prevent cancer? So,can cancer be prevented? Researchers from the American Cancer Center published a research paper in the Journal of the American Medical Association: Internal Medicine, saying that through data analysis of 1.44 million people in the United States and Europe, they found that the incidence of at least 13 cancers in people who exercise for a long time is significantly lower! So far, this is the largest and most comprehensive study of articles on exercise and cancer incidence. The paper in the Journal of the American Medical Association integrates many previous research data, surveyed the daily exercise volume of 1.44 million people in Europe and the United States, and then compared the two groups of 10% who exercise the most and the 10% who exercise the least. The entire exercise research data statistics span from 1987 to 2004, spanning 18 years, and the cancer incidence data tracking time is longer. How can sports prevent cancer? What is the principle of exercise to prevent cancer? In recent years, sports medicine research, tumor experimental research, and tumor cause investigation have gradually revealed the mystery and clarified many new mechanisms. 1. Improve the body's immune function and help prevent cancer Studies have found that cancer cells can only grow and reproduce when they escape human immune surveillance; if a person's immune mechanism is intact, no cancer will occur; if cancer patients can maintain and improve their own immune function, they can effectively Suppress and defeat cancer. Studies have confirmed that regular exercise can effectively improve autoimmune function. For example, exercise can significantly increase the body’s immune cells such as T lymphocytes, B lymphocytes, and phagocytes, thereby enhancing the body's ability to prevent cancer. Exercise can also increase the level of interferon in the blood, and interferon is also the body’s immune enhancer, which has anti-cancer and anti-cancer effects. 2. Breathing in more oxygen is beneficial to inhibit cancer Exercise can make people inhale several to several tens of times more oxygen than usual. The human body's oxygen intake increases and the breathing rate increases. Through the frequent exchange of gas in the body, more carcinogenic toxins can be discharged and the incidence of cancer can be reduced. At the same time, cancer cells are anaerobic cells that require insufficient oxygen for survival and growth. The environment; the internal environment with sufficient oxygen is not suitable for the growth of cancer cells, so it is more conducive to inhibiting cancers latent in the body. According to the research of German sports medicine professor Van Aken: "A person gets more than 8 times more oxygen per day than usual, which can prevent cancer, and even if they have cancer, they can prolong their life." Mexican oncologists tested 100 cancer patients. Three years of experimental observations found that with 2 hours of oxygen therapy a day, the survival rate of cancer patients can rise from 32% to 88%. 3. Prevent cancer cells from "settlement" and "metastasis" Human blood circulation speeds up during exercise. At this time, cancer cells are like small sand in the turbulent flow. They are not easy to "stand on their heels". Therefore, it is not suitable for cancer cells to "settle" to form spreading and metastasis; they are often affected by immune function during blood flow. The strong immune cells are eliminated. 4. Exercise can cause more sweating and discharge more carcinogens Every time you exercise, you will sweat much more than usual. Excessive sweating can excrete carcinogenic poisons such as nitrite, acetone, chloroform, sulfur, phenol, strontium, lead, mercury, and beryllium that are accumulated in the body to prevent cancer. 5. Improve the activity of antioxidant enzymes and effectively remove free radicals The human body produces a large number of free radicals in its metabolism. The accumulation of excessive free radicals in the body can damage cell membranes, proteins, nucleic acids and induce more than 200 diseases. It can also cause cell mutations and develop cancer. However, the human body also has a system for removing these free radicals. The function of scavenging free radicals is called "anti-oxidation". For example, superoxide dismutase and glutathione peroxidase in the human body are antioxidant enzymes that can effectively scavenge free radicals. The higher the activity of antioxidant enzymes in the human body, the stronger the function of scavenging free radicals, which can prevent many diseases and even cancer. 6. Exercise regularly to control blood sugar levels and "starve" cancer cells Nobel Prize winner Dr. Otto Warburg discovered for the first time that cancer cells and healthy cells are fundamentally different in terms of energy metabolism. Cancer cells ferment glucose in an anaerobic environment. Its absorption of glucose is 3 to 5 times that of healthy cells. It directly uses blood sugar as nutrition and almost only eats sugar. Regular exercise can promote metabolism, control blood sugar, maintain a good blood sugar level, and can selectively “starve” cancer cells present in the body, which is beneficial to cancer prevention and anti-cancer. 7. Prevent fat and lose weight, reduce the risk of multiple cancers Studies have shown that obesity is closely related to the occurrence of certain cancers. Obesity in men can increase the incidence of colorectal cancer and prostate cancer; obesity in women can significantly increase the incidence of uterine cancer, cervical cancer, ovarian cancer, breast cancer, and gallbladder cancer. And regular exercise can prevent obesity and have a weight loss effect. People with normal weight should consume all the calories they take in through exercise every day to achieve a "balance of income and expenditure" to prevent gaining weight; while for obese people, the calories consumed every day should exceed the calorie intake, which is beneficial. lose weight. 8. Exercise promotes bowel movement, avoids constipation, and helps prevent cancer The stool of the intestinal cavity contains a variety of carcinogens and carcinogens. For people with frequent constipation, the carcinogens and carcinogens in the stool can stimulate the intestinal mucosa in a large area, high concentration, and for a long time and easily induce a variety of cancers. Exercise can promote bowel movements, accelerate bowel movements, reduce the concentration of toxins in the stool, reduce the area of contact with the intestinal wall, reduce the time to stimulate the intestinal mucosa, and greatly reduce the risk of cancer. 9. Female friends who insist on exercising are particularly effective in preventing women's cancer Medical experts conducted a 21-year investigation and research on 8,000 Japanese in Hawaii and confirmed the effect of exercise on cancer prevention. In particular, women benefit more from exercise. Research results show that exercise can regulate female endocrine hormones (such as estrogen, prolactin), thereby reducing hormone-dependent breast, ovarian, uterine, and other gynecological cancers by 50%. American cancer expert Jerome Bullock pointed out that the most reliable way to prevent gynecological cancer is to insist on aerobic exercise for 3 hours a week. Exercise can prevent a variety of cancers related to endocrine hormones. 10. Exercise can invigorate people and improve their ability to prevent cancer A well-known American oncologist pointed out: “Cancer is the failure of immune function, and the failure of immune function occurs after the mental balance is disrupted.” Clinical diagnosis and treatment have observed that about 3/5 of cancer patients are due to trauma and emotional depression. And suffering from cancer or causing cancer to develop. Persistent exercise can regulate the secretion of human hormones, promote blood circulation in the brain, invigorate people, and cultivate sentiment. Exercise can make the human body secrete the brain chemical substance called “the river of happiness of consciousness”-cephalin. The chemical substance can regulate the function of the nervous system, improve mental stress, exercise will, make people feel happy, help eliminate worries and worries and improve the ability to prevent cancer. Which cancer risks can be reduced? Regarding the cancer risks that exercise can reduce, this article studied 26 types of cancer and found that exercise significantly reduced the incidence of cancer. The percentage of reduction in the incidence of 13 types of cancer is shown in the figure. Of the top 10 cancers in China, 8 of them can reduce the risk through exercise. Esophageal adenocarcinoma was reduced by 42%! Liver cancer 27%! Lung cancer 26%! The cancers with the highest mortality rates for men and women in my country are lung and bronchial cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, accounting for three-quarters of all cancer deaths.In order to make the conclusion rigorous, the researchers analyzed the surveyed subjects’ race, geographic location, education level, age, body weight, smoking, drinking status, hormone therapy, and other conditions and found that the above conclusions are not affected. How long is the best exercise? Understand the principle that exercise can prevent cancer, so what exercises can prevent cancer, and how long is the appropriate exercise time? Experts from the American Sports Association believe that aerobic exercises such as jogging, cycling, and swimming are most suitable. The ideal exercise rhythm is three times a week for at least 30 minutes each time, or four times a week for at least 20 minutes each time. As long as you go to the gym and walk or jog easily, you can easily achieve this rhythm. It is important to persevere. In fact, in summary, exercise does not really prevent cancer from occurring. It can only help you exercise your body, regulate immunity, and reduce the chance of cancer, but excessive exercise will also reduce your body’s immunity! In addition, there are air, water sources, mentality, etc. that affect your health.Exercise is not omnipotent, but no exercise is absolutely impossible!
Braking is simple, just press the lever, but is it really that simple? Of course not, let's take a look at the correct way to break! The front brake is important Many novice friends don't like or are afraid to use the front brake. In fact, the front brake is still very useful. Especially in the case of emergency braking, the front brake is more efficient than the rear brake. But you need to pay attention to two issues. The focus should be shifted back if you don’t want to fly out. Also, the brakes are now very easy to lock, so be sure to pay attention when using the front brake. This can be felt slowly while riding. If it is downhill, you can't just use the front brake, you need front and rear cooperation.It is not recommended to use the front brake when cornering. It is easy to slip. When using the front brake, the wheels must be straight. The rear brake is not that safe Many friends think that it is safe to use the rear brake. In fact, the rear brake is also very dangerous, especially in the case of high-speed riding. If the rear brake force is too strong, the rear wheel will lock and the rear wheel will slide. Sand or slippery, the consequences are disastrous. Friends who often ride bicycles must feel this deeply. Of course, the role of the rear brake is still great, mainly depending on the road conditions and your riding situation. When riding slowly, in bad road conditions, such as slippery roads or when the front brake of the front wheel fails. The rear brake works very well. Do not brake to the end, it is better to brake if it is a particularly critical situation.There is no fixed requirement for left front right rear or left rear right front. It depends on personal habits to adjust. Is disc brake or v brake better? This is a problem that many novice friends struggle with. In fact, the two cannot be compared at all. Different types of things have their own advantages and disadvantages. The biggest advantage of the v-brake at present is that the structure is very simple and convenient for maintenance.Therefore,the v-brake is generally chosen for long-distance riding. Disc brakes can adapt to a variety of environments, and the rain will not affect the braking efficiency.

1.Too tight Bicycles have become lighter and lighter, and the fault-tolerant rate of installation is getting lower and lower. Excessive torque will cause slippage of the chainring, twisting of the handlebars, and serious breakage during cycling. For many novices, some torque values seem very low, especially most of the control components. But in fact, these parts don’t need so much torque! The brake lever is a good example. The torque required to install the brake lever is usually only 4 Nm, which looks a bit weak, but it is enough to prevent the brake lever from turning up and down. Moreover, the lower torque can ensure that in the event of uncontrollable events such as crashes, rotation, and absorption of energy occur to avoid damage to accessories. Although you need to readjust after this, it is better than seeing a broken brake. Don’t forget to use a torque wrench, trust the recommended torque value when installing any components! 2. Spend too much/too little on accessories Of course, we can’t tell you how to spend your money, so if you have a large budget, just spend it. However, for those who have to plan carefully, some upgrades will appear to be much more. Those fancy/expensive carbon fiber handlebars may not enhance your riding experience. However, relatively inexpensive components like tires can have a big impact on your handling and average speed. 3. Do not bring spares, tools, etc. Your mountain bike can take you to some amazing places, which means that it is necessary to bring spare supplies and portable tools, at least to ensure that you can come back from deep in the mountains. Such as inner tubes, tire sticks, portable tools, and pumps are undoubtedly essential items! But if you plan to go further, or the riding environment is worse, then we have some suggestions worthy of reference. Such as a pair of brake pads, a pair of magic buckles. 4. Tire pressure is too high Too high air pressure is a mistake that almost everyone has made, especially those stubborn novices. Although too high air pressure will not cause snake bites, it will greatly reduce tire grip and reduce comfort. These two points should be avoided! We recommend starting from around 30psi and increasing or decreasing the tire pressure a little. Generally speaking, you will choose a slightly lower tire pressure to get the best grip and comfort, while excessive reduction may lead to snake bites. I know some truths are unclear, if you don’t believe it, please try and make mistakes yourself! Certain experiences should really make you try. 5. Like spray lubricants such as WD-40 If you want to clean disc brakes, choose a special cleaner like Muc Off. If you have to use a lubricant like WD40, don’t lose the slender plastic tube, it can lubricate the parts you need more accurately.
Learn how to take your own measurements - use a measuring tape and a level to accurately measure the various components of your bike. When it comes to mountain biking, finding the right frame size for your body is essential. To ensure you get a bike that fits perfectly and offers you the best riding experience possible, it's important to take accurate measurements of your body and compare them with a mountain bike frame sizing chart. This article will provide step by step instructions on how to measure a mountain bike frame. First, you'll need to measure your height and inseam length. To measure your height, stand straight with your back against a wall and use a measuring tape or ruler to measure from the top of your head down to the floor. For the inseam measurement, stand up straight and have someone help you measure from your crotch to the floor. Make sure to record both measurements in inches. Next, you'll need to measure your mountain bike frame size. To do this, you'll use a measuring tape and a level, as well as the height and inseam measurements you recorded earlier. Start by measuring the top tube length of the frame, which is the distance between the seat tube and head tube. Then measure the seat tube length, which runs from the bottom bracket to the top of the seat tube. Finally, measure the standover height, which is the measurement from where your crotch rests on top of the frame when standing over it with feet apart. Once you have all of your measurements, you can compare them to a mountain bike frame sizing chart. This will help you determine what size frame is best for your body type and riding style. It's important to note that every brand has their own sizing charts so make sure to consult the appropriate chart for your specific bike. Taking these measurements can seem intimidating at first, but with practice and a few helpful tips it can become second nature. This article has provided an overview of how to measure a mountain bike frame and how to compare your measurements to the appropriate sizing chart. With accurate measurements, you'll be well on your way to finding the perfect fit for your next mountain biking adventure.Good luck!
Attaches the handlebars to the bike, or, more precisely, to the steerer tube. Stems are designed differently for different headset types (i.e. threaded or threadless). They are also sized to suit different diameter handlebars and in the case of threadless setups, different diameter steerer tubes. Stems play a key role in setting your riding position. You can adjust the reach to the handlebars by changing the stem’s length. Separately, you can move the stem vertically to change your riding position. Stems for road bikes typically come in lengths ranging from 80 to 140mm. Mountain bikes have moved to significantly shorter stems than this. If you need a stem much shorter than 80mm on a road bike, that is a sign the bike doesn’t fit you. All else equal, a shorter stem will make for quicker handling. If you are buying a new bike and you know you need a different stem length, the bike store should be willing to trade your stem for something they have in stock. Another characteristic of stems is their angle. Threadless stems commonly come in angles around -10 degrees, sometimes more. You can flip a threadless stem so that it increases the height of the bar. There are also angle-adjustable stems made, so the rider may change bar positions without removing the handlebars or changing the stem, although their length typically can’t be adjusted. Trifox also has some stem accessories: Road Bicycle Handlebar Stem ABS100 is made of 6061 Aluminum Alloy, with 7° up rise, suit for 31.8 Handlebar and 28.6mm Fork, for Mountain Bike (MTB) / Road Bike.
Peilin Hubs refer to the bearing drums of bicycles, which are divided into double-bearing types and four-bearing types. Peilin hub is a transliteration, which is derived from foreign bicycle manufacturing technology. The bearing hub has the characteristics of good sliding and easy maintenance. Ordinary Hubs are loose beads, such as most of Shimano’s products and civilian-grade Hubs. The Peilin Hub is a bearing drum. The standard bearing is installed in the drum shell, which makes the rotation smoother and quieter. There is no need for adjustment and maintenance, and the waterproof and dustproof performance is higher. The front drums of Peilin hubs are generally double-bearing, and the rear drums are divided into two types: double-bearing and four-bearing. The strength of the four-bearing is higher. Bearing hubs are divided into double bearing types and four bearing types. The front drum is often double-bearing, and the rear drum is divided into two types: double-bearing and four-bearing, and the strength of the four-bearing are higher. Whether the rear hub is four-bearing or double-bearing, it is actually two bearing bearings. The other two bearings in the four-bearing hub are mainly used to support the operation of the hub wheel, and basically do not play a load-bearing role. Therefore, the strength of the four-bearing and double-bearing hubs is basically the same. There are slight differences in structure between the four-bearing and double-bearing rear hubs, mainly in the ratchet part:The four-bearing hub is to place two assembled bearings directly in the freewheel body. The freewheel body can usually be made of aluminum alloy material; the double-bearing hub is composed of a shaft bowl, axle gear, and balls set inside the freewheel body. Therefore, the tower base is made of steel. In this way, from the perspective of the overall weight of the rear hub, although the four-bearing hub has two more bearing assemblies, the actual overall weight is lighter than that of the double-bearing hub due to the use of an aluminum alloy freehub. The advantage of the bearing over the bead gear is that it glides well and is easy to maintain. Our company also has bike hub accessories: Trifox Bike Hub M827 For MTB, its advantage is the freedom to change the quick release and barrel shaft, the tower base is broken do not have to worry about throwing the whole thing away, were broken to change where you can buy MS tower base and XD tower base replacement alone, and there are a variety of colors to choose from. If you still have any questions, you can come to our official website.
Here’s a picture of a road bike. Before introducing the parts of the bicycle frame, let’s take a look at a picture: There are roughly such things on the whole vehicle: Frame, Front Fork, Wheelset, Seat cushion, Handlebar, etc. Whether it is a self-assembled vehicle or a brand-name vehicle, the first part to choose/focus on should be the frameset! What frame you use represents what you are riding. Since road cars pursue higher transmission efficiency, they are basically without shock absorbers. Therefore, most of the frame + front fork (frameset) are sold in bundles. Some frames also use odd-shaped (non-circular) Seatposts, as well as accessories such as seat posts. What’s the frame? In general, almost all parts of the bike are mounted on the frame. Let’s start with the front fork of the frameset, after all, it’s a bit simpler… ↑There is also a front fork in front of the frame, which is connected to the frame by a part called a “Headset” to provide a steering mechanism. ↑Looking at the front fork from another angle, the front fork has several parts: the top tube, the fork shoulder, and the fork foot. The top tube is used to install the handlebars and other parts, the fork shoulder is basically meaningless on a road bike, and the fork foot part is used to fix the front wheel. Most of the parts will be installed in the frame part, the soul of the whole car mainly lies in the frame. Then there is the frame part, which mainly consists of the following parts:Headtube, Top tube, Down tube, Seat tube, Seat stay, Chainstay, Bottom bracket.These are all marked in the figure and also rear fork feet for mounting the rear wheel, as well as tail hooks for mounting the derailleur and front derailleur mounts. ↑The bottom bracket part of the frame can be said to be the strongest part of the vehicle. In the center of the picture, there is a metal part that is fixed by two screws and protrudes. This is the front fork hanger/mount. In the chainstay part, the side with the paper tape is attached to the tail hook. When buying a road frameset, in addition to the frame and front bike, you will generally have a seatpost, seatpost clip, spare rear hanger, headset, washers, cable mounts, and a range of small accessories. Note: If you purchased a frameset, be sure to read the manual to double-check that all accessories are complete. In addition, 700C AERO Carbon Road Bike Frameset X8TA adopts carbon fiber integrated molding process, three-dimensional guide type integrated aero pipe type, internal routing aerodynamic propel design, full sense of strength, the combination of sports and equipment aesthetics, and the special processing method of carbon fiber makes the frame without Joint gaps, with consistent visual aesthetics that other frame materials don’t have. The internal routing design, the wiring from the upper tube of the frame head, is simple and beautiful.
Because road bicycles are fast, strictly speaking, the requirements for cadence are greater than the requirements for strength. So, how to increase the cadence and rhythm? That is to sweat more and practice more during normal training. The so-called one minute on the field, ten years off the field. Any exercise needs to be done step by step, no one can practice it in one day, so how do improve the cadence and speed? ①. Keep the cadence at 80 to 90 revolutions per minute on flat roads. If there is a gentle downhill on the flat road, you can raise a grade and stabilize slowly. ②. Keep going uphill at 65 to 75 rpm, if the slope is too big, you can lower it a notch and then slowly stabilize. ③. Alternate intermittent and static riding to improve resilience during competition. ④. Practice more straight-line riding skills, S-type riding will consume too much energy and reduce cadence. ⑤. It is enough to shake the bicycle when the bicycle is rocked. When the bicycle is rocked, the body will follow, which will consume too much physical strength and disturb the rhythm.
