If you often ride on the roads in the suburbs, the probability of a bicycle blowout will increase several times, because the roads in the suburbs are not cleaned by special personnel like the roads in the city, so there are more foreign objects. However, in the case of long-distance riding or outdoor off-road Next, a flat tire is a very distressing thing, so how can we effectively prevent a flat tire? Let us take a look together： First：Precautions against tire puncture Inflate enough, be sure to inflate enough, if there is an air cylinder for a barometer, please hit it close to the air pressure number marked on the tire. If you don’t have a barometer, feel it with your fingers. Generally speaking, the road bike should be hit until the tire can’t be squeezed with fingers (big man’s hand). The mountain bike can still be pinched when it is knocked down, but it is very, very hard to pinch. The benefits of high tire pressure are obvious. The tires are hard, and many sharp stones, broken glass, and the like will be bounced off after being hit, and cannot be pierced. Greatly reduces the chance of being stuck. When parking for a rest, pay attention to check the outer tire to see if there is any broken glass, small iron pieces, stones, and the like embedded in the outer tire, and clean it up in advance. These things may not puncture for a while, but the speed and distance of riding will make them go deeper and deeper until they puncture the inner tube. When riding a bicycle, watch the road and avoid suspicious things on the road. In addition, try to walk as close to the middle of the road as possible. Generally, glass and iron sheets are mostly on the side of the road. Second：Precautions against cracking The only reason for this is that the tires are under-inflated, so the tires are too soft, and there is not enough support when they hit hard objects, causing the inner tube to be squeezed towards the rim and smashed on the rim. It may also be the factor of the outer tire. Regularly check the foreign matter on the outer tire. Many times, small stones and glass shards stuck to the tire but did not puncture the tire. If you don’t deal with it in time, as the riding increases, these foreign objects may get deeper and deeper, eventually leading to a puncture. The preventive measures are the same as above: cheer up and watch the road more. Third：Burst Precautions This is usually due to tire problems. One is that the tire pad cannot withstand the high pressure, and it deforms too much inward or even ruptures, causing the inner tube to burst inward. The second is that the tire pads were not properly padded and moved, causing the holes on the rim to directly contact the inner tube, and burst under high pressure. The solution is to choose tire pads that can withstand high pressure. If the tire pad is narrow and easy to slide, first wrap the inside of the rim with something like 3M tapes to cover all the holes. Moreover, it can increase the friction of the tire pad and reduce the possibility of slipping. Fourth：Slow Exhalation Precautions This situation is generally a quality problem with the inner tube. Inflate and check in advance before installing the inner tube. The spare tire you carry when you go out should also be checked in advance. Slow air release generally occurs at the mouth of the air, which is the place to focus on inspection. In addition to the above situation, there is another situation that after a puncture, the inner tube has just been replaced, but the air leak is soon discovered. There are two possibilities for this. One is that the thing that punctures the inner tube remains on the outer tire. The preventive method is to carefully check the outer tire when repairing the tire. For the position of the broken tire, carefully mold the inner side with your hands to confirm that there are no foreign objects. Another possibility is that the tire lever pinched the inner tube when installing the outer tire. The preventive method is to practice the tire-changing technique hard.
Regarding the importance of cycling helmets and cycling gloves, let's not mention them. Everyone should know them very well, and they should wear them every time they ride a bicycle. However, if there is no correct way to wear it, does everyone feel the same as not wearing it? The helmet must be worn horizontally and cannot be tilted forward or backward!The correct method is as follows:How does the helmet protect you? If you fall, the helmet will break, not you. The purpose of the helmet is to rupture, which is what the helmet should do. The material used in the helmet is a kind of material that breaks when it is hit by a sudden impact. When the head hits something, the helmet will shatter or break. This is the role of the helmet to protect the head. (That's why the helmet is called the “head bucket”) The helmet is designed to withstand at least one impact! After any collision, the old helmet must be replaced. This is what the helmet does.
With the popularity of cycling, more and more bicycle enthusiasts have used self-locking pedals ("locked pedals" for short).Perhaps most people have grown up riding bicycles, and they will feel that lock pedals are completely unnecessary, but many people who have used lock pedals will not change back to the previous riding method with horizontal pedals. Why?In summary, there are two points:First, save effortThis is the best effect for aerobic exercise which consumes a lot of physical strength.Generally speaking, using self-locking pedals can save up to 25% of your effort, and you can easily climb hillsides that were difficult to ride before.Maybe you will be uncomfortable at the beginning, or you may find it to no avail, but after using the lock, the action will become natural. Sometimes you can also do low-speed off-mount cycling movements, which look very professional. But cycling fast is not good. If you remember to step and forget to pull or remember to pull and forget to step, it seems to take a while to get used to.Leaning forward, stepping on the front foot, and pulling on the back foot, the human and vehicle feel very beautiful together. This is an unusually smooth sensation of two feet riding the chain wheel to rotate in concert.Second, stabilityPeople who have used flat pedals know that they must step on the pedals on the bumpy rocky road to prevent their feet from loosening. They have no idea of stepping hard, but if they use self-locking, they don't have to consider using their feet to find them. It's troublesome to pedal this. You can just pedal hard, as long as you hold the handlebars, the problem of catching your feet will be fixed for you.If you don't use the lock pedals well, you will also be dangerous. You may not be able to adapt quickly when you use the lock pedals. People who are accustomed to using horizontal pedals when parking unconsciously stop when parking. This habit often makes Beginners make jokes, such as "zero speed fall".The person who steps on the locking pedal will take off the pedal when it is parked. Because it takes a while to exit the lock state, it takes a while.Especially beginners are not proficient in unlocking. At this time, he can't take off the pedals at once, and at the same time loses his balance, he has to fall to one side of the ground. If there is a bike on one side, it is more dangerous. Therefore, it is recommended that beginners have to practice the process of getting off the bicycle in the initial use, and have the consciousness of removing the pedals before stopping.A good lock pedal is not enough, a good pair of lock shoes is also essential, the quality of the shoes also directly affects the use of the locking pedal. The sole should be hard, and the heel of the shoe should be tight but not uncomfortable. When unlocking, there should be no gap between the foot and the shoe, so that you can fully feel the joy of riding the bicycle.Not to mention the benefits of using the locking pedal for long-distance cycling, it can change the power distribution of the legs, and the legs of the back foot can also play a role in the lifting, which makes the cycling less fatigue and more high-speed. It takes longer.A very important part of the pedaling system is actually sole, because the pedaling shoes are usually not bent, which can prevent the pedaling force from being consumed by the bending of the arch material, and it cannot be transmitted to the pedals in a larger proportion. Virtually every foot is riding with greater efficiency.
When you are keen on cycling, you are not limited to decompression and relaxation but are gradually eager to conquer different distances. As a result, many drivers want to improve their strength from all aspects through various training methods, so that they can improve by leaps and bounds. Exercise science shows that 30-75 minutes of cycling training can increase your speed, increase your cadence, and enhance your endurance. You can choose from the following training methods: 30-second sprint Warm up for 10 minutes, do a quick 30-second sprint, then slow down and cycle for 2.5 minutes. Insist on doing 12 times, and finally slow down to let the body cool down naturally. Don’t train back to back or more than twice a week. Studies have shown that training in 30-second sprints increases VO2 max — the maximum amount of oxygen your body uses at its limit. increase cadence Warm up for five minutes, switch to a small gear, keep your upper body stable, pedal smoothly, hold on for one minute at the fastest possible cadence, recover for 3 minutes, do 6-8 groups, and finally let the body cool down naturally. Gradually increase training time and decrease recovery time as training becomes easier. If you usually use a large chainring, it will take a while to get used to a high cadence. leisurely ride Ditch the computer and plan your route, and just hop on a bike and get around. Enjoy the breeze and feel the scenery on the recreational trail. This relaxing activity relaxes your legs, restores your strength, and keeps you happy and refreshed. triple challenge Warm up for 15 minutes, then increase the intensity to level 9 (self-perceived fatigue rating, a total of 10 levels), persist at this intensity for 3 minutes, recover for 3 minutes, and repeat more than 2 times. End your workout at a moderate pace and allow your body to cool down naturally. In order to improve physical fitness, you need to push the limits of your body in this way, try to make your lungs burn, and find ways to increase oxygen consumption. climbing training There are two methods. 1.Standard mountain repetition training. Warm up for 10-15 minutes, find a mountain that takes about five minutes to climb, and ride up as hard as you can, maintaining the maximum cadence, or maintaining the limit state (RPE7). Take 3 minutes to recover when going downhill. Repeat 5 times, rest. 2.Take a more organic approach. Plan a 10-15 mile cycling route that includes 4-6 hills. Hard on the climbs, moderate rides between hills. As the old saying goes: Mountains make you stronger. Beyond the limits Warm up for 10-15 minutes, increase the intensity, reach RPE8, and persist for 5-6 minutes. Reduce intensity, below RPE6, for 5 minutes. Do 3 or 4 sets. You won’t feel a full recovery between sets. Finally, let the body cool down naturally. High-intensity riding requires you to actively push hard and keep your legs durable. That training is all about building endurance. speed training Warm up for 10 minutes, increase the speed, and reach the same sustainable speed as the 40km time trial (intensity is about PRE7). Hold for 15 minutes, then lower the gear, relax for 3 minutes, and repeat more than two times. With the deepening of training, it is necessary to increase the training time, reduce the recovery time, and finally increase it to 1 hour. , Speed training makes cells more efficient in generating energy, increases physical limits, and enhances endurance. lunch break Grab some friends, sneak out, and work on your weight-bearing capacity. Use different queues to ride: single row, double row, or a combination of single and double to challenge each other. Riding with a small team can exercise balance, riding technique, and weight-bearing ability. In addition, it is also full of fun. stable state Ride for more than an hour at moderate intensity (RPE6). It is very difficult to maintain this intensity. Make sure you are breathing evenly and that your legs are not burning. This approach improves fat utilization, reduces reliance on carbohydrates and sugars, and increases endurance. Gradually, you’ll go farther, feel more comfortable without slowing down, and stabilize faster.
Just like playing ball, dancing, and running, you can lose the fat on your body, and sweat profusely so you can look healthy. Our bikes should not be simply regarded as a means of transportation but should be regarded as a kind of fitness equipment. On occasions, this is irresponsible for it, often wash and maintain the bike after Cycling is a journey Of course, travel should not be a short 10 kilometers or 20 kilometers. This distance is too short for cycling. How far is it? In fact, there is no specific number. Traveling should be from the place where you are to a strange place, or a place you have been to but not often so that you can have a different experience, so that it is not boring, and you can bear the wind and dust on the road. It is full of anticipation for the scenery ahead. So when you have been around, riders who have time will want to go further – travel! Riding is a conquest From 300 meters above sea level to 600 meters, to 1000 meters higher, when you climb to the top of the mountain and look out, you will feel proud and satisfied. A thrill of conquest. So I kept looking for higher mountains and harder paths. Of course, you have to remember that what you conquer is actually yourself. Riding is a challenge Challenge your physical limit, challenge the peak of your perseverance, challenge your opponents, challenge the wind, rainstorm, cold, and hunger, and become stronger in constant challenges. Cycling is a kind of sharing Record the beautiful scenery you see, upload your feelings and feelings to Qiji or Moments, and let family and friends share this trip together. Although others have not gone, they can also feel happy from your sharing, as if they have also been there Same. At this time, we have also become the scenery of others. Cycling is communication Traveling with cyclists, chatting and laughing on the road, chatting freely, exchanging life thoughts, exchanging riding experience, exchanging knowledge about cycling, you can say hello to unfamiliar cyclists, and make progress and grow together in communication.
The tire is one of the most easily consumed parts of a bicycle. The little friends who buy a bicycle must have a lot of questions: What kind of tire is more suitable? How to pay attention to the maintenance of tires? When should I change the tire?Today, I will take you to talk about the related knowledge of tires and how to solve these problems. I believe this article will give you a comprehensive understanding of the tires.Bicycle tire classificationMountain Bike TiresThere are many subdivisions of mountain bike tires. Here, I will introduce three major categories: Cross-country Tires, bald tires, and semi-bald tires.Cross-country Tires for off-road useOne of the most common mountain bike tires.This type has an obvious deep tooth structure, the distance between the tooth patterns is also quite large, the grip ability is good, it will also bring a certain shock-absorbing effect, and the ability to resist sand is also good. It is a more versatile mountain bike tire. Ordinary MTB XC and the road bike are acceptable.Bald tireAs the name suggests, bald tires have very fine lines, almost similar to road tires. The reason for its birth can also be the imagined-in pursuit of speed. This type of tire has low resistance, can speed up quickly, and can reach the limit of mountain speed.If you are after speed and most of your cycling roads are urban asphalt roads, bald tires are your best choice. Of course, bald tires have almost no grip and are more prone to crashes.Semi-bald tireThere is no deep-tooth structure in the middle of the tire, and the cross-country tire structure with an obvious deep-tooth structure on both sides. This has the characteristics of low resistance of bald tires, which is suitable for riding on urban roads and has a good gripping ability. It is also a good choice for in the wild.If you commute in the city and go off-road on weekends, semi-bald tires are your best choice. (Of course, you can also choose bald tire for front wheel and Cross-Country tire for rear wheel, which will also take into account the two riding conditions.)Road Bike TiresThere are generally three types of road bike tires, clincher, tubular, and tubeless tires.Clincher (embedded tire)It needs to be used together with the inner tube, which is our most common bicycle outer tube. Its function is to bear the load of the vehicle, and at the same time limit the size of the outer edge of the tire, protect the inner tube and tire pressure, and prevent the inner tube from mechanical damage. The advantage is that it is convenient to repair in case of flat tire leaks. Trifox Carbon Road Bike Wheelset WT11 using Clincher Tire.Tubular tireThere is no distinction between the inner tire and the outer tire in the traditional sense. This high-performance outer tire is pasted with a tread on the stitched casing and then glued to the tube tire rim, which needs to be used with a special rim. For general road bike competitions.Most professional players also use tubular tires, their advantages are:1. Good turning performance and more comfortable;2. Excellent shock absorption performance, less chance of single jump and deceleration on rough roads;3. The maximum inflation pressure is higher than that of a clincher;4. When encountering a high-speed downhill puncture, the tire will not fall off instantly, which can avoid the accident and allow the driver to continue to move forward and wait for backup;5. The rim of the tube tire is lighter.Of course, for amateur players, there are many disadvantages:1. It is troublesome to change tires, whether it is a flat tire or a long-distance ride, you need to change a new tire;2. Repairing is extremely troublesome, which affects the life span and increases the use cost a lot.Tubeless tireAlso known as "low-pressure tire" and "pneumatic tire", there is no tube. The assembly of tires and rims is sealed by a special vacuum nozzle filled with sealant or self-refilling fluid. Most wheelsets also need special tubeless tire pads. Since the fit between the rim and the tire must be completely airtight, only certain rims are compatible with vacuum tires.Advantages: low rolling resistance, due to the low tire pressure required, the comfort will be good, and it will self-repair some small perforations.Disadvantages: It is relatively heavy and difficult to repair when encountering major problems. Low tire pressure also reduces the speed.Focus on !!!In fact, with the development of technology, the performance and speed of clincher tires have been greatly improved, and the weight has been reduced. The difference between clincher and tube tires has become smaller and smaller, especially when using latex inner tubes. I Will not feel the difference between the two.Precautions for daily care and maintenance1. Pay attention to tire pressureInflation should be moderate, under-inflation and over-inflation have many disadvantages. Insufficient inflation causes a flat tire, which increases the riding area, increases the riding resistance, and increases the wear of the tire; if the inflation is too high, if the temperature rises in the summer, the gas expands, and the tire cord is easily expanded. It will shorten the service life.2. Clean the tireAfter riding the bike, check whether the tires are mixed with pebbles, broken glass, etc., clean them up in time, rinse with water, and finally wipe them with a dry cloth to prevent grease, hydrocarbons, and corrosive substances from sticking to the tires. Cause the tire to deteriorate, but also to prevent direct sunlight.Before riding, check again to see if there is any sharp debris such as glass slag on the tires and clean them up in time.3. Choose road conditionsWhen riding, choose reasonable road conditions, avoid wastes such as glass slag, and avoid road conditions such as manhole covers and pits.When should the tires be changed?1. Wear: Observe the tread and sidewall of the tire. If the tread is flat and square, it must be replaced;2. Scars: Whether the fabric in the pipe wall has leaked out, if there is, it means that the cut is deep, and it must be replaced as well;3. Cracks: Observe whether there are cracks or odd-shaped protrusions on the surface of the tire. If there are more, replace them;4. Riding distance: Generally, if you ride about 5000km, you need to replace a new tire.
The various rolling bearings used in bicycles (mainly hubs, bottom brackets, headsets, pedals) can be simply divided into bearing and ball gear bearings.So what exactly are bearing shaft and ball gear bearing?The bearing shaft actually refers to a shaft that uses an industrial deep groove ball bearing assembly as a rolling bearing. The structure can be seen in the figure below. Its characteristic is that it can be repaired by replacing the bearing assembly when damaged.The ball gear bearing is composed of a bowl, a shaft gear, and a ball in the middle. They and the hub body together form a large bearing. Because the ball does not need to use a cage-like industrial bearing, the ball gear structure bearing of the same size can accommodate more balls, and each ball has a larger contact area, which can withstand greater pressure.All Trifox carbon fiber road bike wheelsets use bearing hubs.
Many riders have bought cycling pants. Considering hygiene, protruding pants, appearance, etc., they often consult whether to wear underwear or not.Answer: After wearing cycling pants, underwear is no longer suitable.The picture below can prove that professional riders do not wear underwearIn 2003, the Austrian cyclist Hasselbacher tried to squeeze along the border fence during the sprint stage of the third leg of the Tour de France on July 8. As a result, he fell heavily and his clothes were all covered. Was scratched. However, despite the ragged clothes, Hasselbacher even showed most of his buttocks, still stepping on the bike to continue the race.On July 07, 2004, on the third stage of the Tour de France, Hushofder exposed his buttocks to complete the race.Chris Froom was treated after a crash on the fourth stage of the 2014 Tour de France.The benefits of wearing cycling pants for cycling are:1. Reduce wind resistancev2. Increase the comfort of the buttocks and saddle3. Reduce friction4. Quick-drying wicking functionThe reason for reducing friction is that long-distance cycling pants rubbing the skin for a long time will produce varying degrees of inflammation or other skin problems, and the material of cycling pants can effectively reduce friction. If you wear underwear, the friction-reducing effect of the cycling pants will be isolated, and it will not work. And the underwear is generally made of cotton, which has a poor sweat-wicking function, moisture + large friction, which is harmful to the human body!
Before each ride·Check the tire pressure·Check the brakes and cable sets·Confirm whether your crank setting is locked·Confirm whether your Quick Release is locked, but not too tightAfter each ride·Check whether there are glass, sand, and gravel fragments on the tire and whether the tread pattern has been ground·Check wheel accuracy·Clean important mechanical parts on the bicycleEvery week or every 320 kilometers·Greasing the chain (dry lubricating oil, or wet lubricating oil when cycling frequently)Every month·Clean up the bicycle completely, and clean the drivetrain system if necessary·Check the chain and freewheel, check the degree of wear of the chain, and whether the chain is loose, and replace it with a new chain if necessary·Check the brake system and drivetrain cable·Check the pedals and SPD shoes for some lubrication·Check if there are any missing parts:·Stem screw·Handlebar screw·Seat post screw (or quick release)·Bike saddle·Drivetrain screw·Bottle cage screws·Frame mounting bolt (thread fixing place)·Brake and drivetrain cables·Brake, shift lever screw·Brake screw (do not change the brake center)·Check whether the tires are worn and rotated smoothly, and replace them if necessary.Every three months·Clean to shiny bikes can always ride faster and farther·Check whether the paint on the frame and the front fork is cracked or raised, which may indicate damage to the structure or part of the bike; pay special attention to the welds of all frames·Visually inspect the bent parts: Rail, Seatpost, Stem, Handlebar, Brake caliper, and Brake leverEvery six months·Check and adjust bearings, pedals, and bottom brackets (if possible: some bearing seals can only be replaced, not adjusted)Per year·Disassemble the bike for maintenance: Replace all bearings (if possible). If you ride more than 6000 miles a year, you must replace all brake cables and shift cables. In addition, people who often ride in the rain or mountain bike riders need to check their bicycles more frequently and thoroughly.Before every important journey, professional inspection and adjustment is a clear choice, which will also make the journey more enjoyable.
