Mountain biking is always full of many unknowns. A crash is inevitable. The helmet can absorb the shock generated by the impact to reduce the chance of head injury. As time goes by, the helmet needs to be replaced after a certain number of years. Ensure that the helmet protection performance is in the best condition. So, how to judge whether the helmet needs to be replaced, let me tell you below.
First, check whether the helmet’s appearance is broken, scratched, or bumpy due to the impact. If there are obvious cracks in the appearance, it proves that you can give yourself an excuse to upgrade the equipment.
In addition to determining the wearing comfort, the helmet fixing device also has the function of fixing the helmet from shaking, making it more fit the back of the user’s head, increasing safety and stability. Therefore, if a helmet fixing device is loose, broken, or worn, it means that the helmet has lost the most basic protective function and needs to be replaced in time.
After the helmet is impacted by the outside world, it will break and deform to absorb the shock. You can check whether there is a gap and separation between the inner edge of the helmet and the EPS foam as a basis for replacement.
These stress positions of the bonnet buckle will cause the gum to become brittle and fracture due to long-term use or exposure to the sun. Regular inspections are required.
In addition to the fixing mechanism on the back of the head, the loosening of the fixing straps on both sides of the temple is also a sign that it needs to be replaced.
After a long period of use, the helmet liner will gradually become thinner and damaged and need to be replaced in time, otherwise, it will affect the wearing comfort. Since many brand helmets are not equipped with an extra liner for replacement, it also means that the helmet liner becomes worn out. Wearing your helmet is not far from retirement.
The “Y”-shaped buckle design of helmets on the market is divided into two types: preset type and movable type. Like the preset type buckle in the picture, the manufacturer has preset the length of the buckle during product design. No need to adjust when wearing. The location of these fasteners also needs to be checked frequently for breaks or looseness. If the above phenomenon occurs, it also proves that the helmet has reached the end of its life and needs to be replaced.
As the most important personal equipment, helmets should be visually inspected before each ride to discover problems in time. Only a fully functional helmet can provide maximum protection. Don’t forget to wear a helmet that protects your head before riding. , remember! A cycling helmet is not as expensive as brain surgery.

Two. Reduce the pressure on the foot, don’t step on or pull
Give up your personal heroism that riding a bike means standing up, using a big gear ratio, and violently trampling on it.
This method is not to increase your pedaling power, but to adapt to the rotation of the chainring
Three. method:
Ride on the bike and use a casual speed
Shift, find a gear, you don’t need to press your body to step on it, and it won’t feel too easy
Imagine your feet are not stepping on the pedals, but floating on top of them, spinning smoothly and calmly
Start the afterburner to accelerate, but don’t increase it suddenly in a step-wise manner. Pay attention to gradually increase your speed, and don’t deliberately step on or pull.
Continue to accelerate until you can’t speak easily and focus on the rotation of the pedal
Keep this stepping for about 1.5 kilometers, trying to rest your muscles while stepping in the middle
This is a kind of mental game. Your feet keep trying to step on and pull, but you have to control them with your thoughts. Don’t do it.
Imagine your feet are spinning gracefully, as the pedals turn into a graceful circle, imagine that the circle gets smaller and smaller, and your speed becomes higher and higher
When you step on the bottom, imagine that your sole needs to be scraped off, so that you can pull your toes down and complete the pulling action.
Due to the COVID-19, many friends are trapped at home or in some other places and lack exercise. Spring is a good season for cycling and fitness. Let’s ride bikes together for health. Before we travel, it is necessary to understand some precautions for outdoor cycling in spring, which will help cyclists to protect themselves.
Pay attention to the choice of time
In the spring, the temperature in the morning is generally very low, the fog is relatively large, and there are more impurities in the air. At this time, it is not suitable for us to travel; the sun comes out, the fog has cleared, and the temperature has risen to a certain extent. At this time, it is more suitable for riding. When doing fitness. If you encounter rain, heavy fog, or blowing sand, try to stop your travel activities to avoid catching cold or suffering from respiratory diseases.
Take care to avoid the wind
There is a lot of wind and sand in spring and the climate is dry. Therefore, it is not easy to expose too many limbs when we are cycling to prevent the spring breeze from causing joint pain and chapped skin. (You can apply glycerin, etc.) At the same time, learn the breathing method of sniffing and exhaling. When cycling against the wind, try to wear a collar that can block sand or dust to prevent choking and dust from causing respiratory diseases such as rhinitis.
Keep warm
In spring, the climate is changeable. It is warm and cold at first. Dress reasonably when riding. It is best to wear cycling clothes to ride the bike. For example, I am wearing Vigmi, which is very comfortable every time I ride. Do not take off your clothes at will between cycling. It is advisable to slightly reduce your clothes when your body feels slightly hot. Don’t take off your clothes and rest at the wind vent after sweating profusely, it is easy to catch a cold and induce a cold.
Pay attention to sun protection
The skin is the largest organ of the human body, so you must pay attention to it. Tanning does not matter. The key is not to get sunburned. Although the spring sun is not very strong, you should also apply waterproof and sweat-proof sunscreen on the exposed skin.
Supplement moisture
No matter how low the temperature is, hydration is necessary and important. Cycling is a kind of endurance exercise. It wicks a lot of perspiration and needs a lot of hydration, while ordinary cycling water bottles seem to have insufficient capacity. Therefore, you must bring enough water for long-distance riding. Water bags are the best. Way.
Supplement energy
Long-distance riding makes it easy for cyclists to exhaust their energy. In this state, people have a poor appetite and basically do not want to eat, so everyone needs to be equipped with corresponding food.
Complete protective equipment
Because the helmet can effectively reduce the chance of a concussion when you fall off the bike, the American insurance regulations stipulate that you must wear a helmet when riding a bicycle, otherwise no compensation is required for an accident.
In addition, the commonly used protective gear when cycling is knee pads, ankle pads, elbow pads, and wrist pads, which can prevent injuries such as sprains and contusions during cycling. If cycling is regarded as a sport, then these protective devices must be equipped.
Warm reminder, cycling is a sport that competes with endurance. Long-distance cycling is easy to cause fatigue and cause accidents. When cycling, you must slow down and follow traffic regulations. Stop and rest as much as possible if you are physically weak. Long-distance cycling is the best Focus on safety, or read more information about safe riding.
When cycling a bicycle, many cyclists have experienced crashes. Now combined with some escape experience, I would like to refer to cyclists for reference.
1. Psychological preparation:
Any sport has its dangers, and two-wheelers are no exception. Cycling is also a two-wheeled sport, which is characterized by a certain speed or the cyclist’s own center of gravity adjustment technology to master the balance, in order to obtain a stable movement posture, and finally drive to the destination. However, during exercise, if this balance is broken, the cyclist cannot adjust it back in time, and the phenomenon of losing balance will inevitably occur. . . An accident appeared here.
Therefore, since it is a sports event, there must be accidents during training and competition. Although protective gear can be used for protection, the degree of protection is still relatively limited. What really plays a decisive role is the driver’s quick response and self-protection actions. So as long as they participate in cycling, cyclists must always be mentally prepared to deal with accidents. Only by facing the accident correctly and keeping a clear and calm mind at the moment of the accident can we make timely and reasonable emergency measures. Protect yourself and reduce injuries caused by sports accidents.
2. Abandon the bicycle:
Loss of balance will inevitably face an abnormal landing. If it is determined that the situation can no longer be restored at this time, an escape action will begin. The first element of escape is to quickly abandon the bicycle. The advantage of separation of people and bicycles is that people can face the embrace of the earth alone, instead of falling into a rolling bicycle. If the speed of abandoning the bicycle is not fast enough, the body posture will change because a certain part of the bicycle is bound to the body, which will have a great impact on the self-protection action after landing. The method of abandoning the bicycle is to throw the bike body to both sides. You must use both hands to throw the bicycle to the left or right, not your feet. If the legs are also involved in the action, it will also bring negative effects, causing the spatial posture of one’s body to change, and the body is slanted to the ground. Even if you have to move your legs, you can just retract your legs over the body of the bicycle to prevent the bicycle from tripping over you. Also remember to throw the bicycle to the sides, not front and back.
3. Landing:
The body must be relaxed before landing, so that the muscles and joints are not tense, the flexibility is high, and the cushioning is good.
The first point: “support”. Support refers to the movement of the limbs (hands and feet) in order to well cushion the impact on the ground, temporarily maintain the body posture, and make adequate preparations for the full-scale landing of the body. Or there are other objects at the drop point, such as big rocks, branches, other riders, etc. . In order to avoid these things, it is very necessary to do a supporting action at this time. The support must be “soft support”, that is, the limb joints (elbow joint, knee joint, wrist, ankle) are properly bent, at a certain angle, and bent close to the body, so as to effectively cushion the impact. If the limbs are straightened, a “hard-to-hard” situation will be formed. Such a wrong support method will directly cause limb dislocations, fractures and other injuries! Therefore, “unreasonable support action is better than no support”, this sentence is very popular in sports, and it is also a very reasonable theory of self-protection technology.
The second point: the torso landed. In any case, be sure to avoid landing on the ground directly. The consequences of frontal landing are very serious. The face and limbs are all directly damaged parts, and the damage is the greatest. Therefore, before landing, change the body posture by turning, let the shoulder and back land, and then add the homeopathic rolling action, this is an effective landing cushioning action.
The correct position of the shoulder landing is the position of the side and back of the shoulder joint close to the back. If it is the front or front side of the shoulder, the clavicle will be broken due to poor bearing capacity, and the shoulder joint will be easily dislocated. Landing on the back is a good way to land, because the back muscles are thicker, and the natural arch can effectively resist impact and protect internal organs. When you land on your back, be sure to bend your neck forward to protect the back of your head. The key is to think “eyes look at your belly” when you touch the ground, so as not to let the back of your head hit the ground.
The third point: rollover. Rolling can reasonably eliminate the inertial momentum of the body forward after landing. At this time, you should relax your body, put your arms in front of your chest to protect your chest, and your legs will bend together naturally. The head should still be bent forward to avoid further injury during the roll. The roll direction is also best to be lateral, the vision will not be greatly affected, and the head is also well protected. If it starts straight ahead or straight behind, change the direction as soon as possible to roll sideways. Get up and flee the scene as soon as possible after the rollover, to avoid hitting you by the vehicles behind you. (The situation will be different depending on the competition event).
Many cyclists will choose to switch to self-locking pedals that can greatly improve pedaling efficiency after cycling for a period of time. However, when the cyclists installed the self-locking pedals for the first time and were so excited to experience the chicness of a “professional cyclist”, they ignored some details of comfort and safety, which led to the possibility of locking pedals. It will not achieve the best effect in use, and it may bring great safety risks.
How to adjust your new pedal comfortably and minimize the potential safety hazards that may accompany the initial “locking”? The following points must be paid attention to!
Installation position of the lock plate
After getting the equipment, we must first install the cleat on the sole of the lock shoe. Don’t think that the cleats can be installed casually, in fact there is a lot of knowledge!
Where is the most suitable position for the cleat? We look from the left side of the picture below: there are two protrusions on the front of a person’s foot, which are on the top of the first metatarsal and the fifth metatarsal. We draw a line between these two protrusions After installing the cleat, the lock shoe is stuck into the pedal. The position where the sole exerts force when stepping, that is, the axis line of the pedal, should be connected to the position corresponding to the position of the cleat. The force position is the standard. If the cleat is too far forward and backward, the best pedaling feeling and efficiency cannot be obtained.
In addition, if your walking habit is out-of-the-foot, the angle of the cleat should be rotated to the inner side of the sole of the foot, that is, the side of the frame. On the contrary, if the walking habit is toward the out-of-the-eight, the angle of the cleat should be rotated to the outside of the foot to balance the pedal When the feet face.
How tight the pedals are
The locks of all brands are designed with screws to adjust the degree of locking. Before officially cycling on the road, we need to adjust the tightness of the lock pedals. The tightness should be moderate when pulling out the pedals. Too tight will make it difficult to “unlock” in an emergency, while too loose may cause the lock pedal to loosen when a large pedaling force is exerted. Both of these situations may bring danger to the cyclist.
Locking/unlocking pedals training before formal cycling
After installing the locking pedal system for the first time, don’t be too anxious to become a “professional cyclist”. Be sure to practice the locking/unlocking movements repeatedly on the spot. After you are proficient, you should also ride slowly on the open and better road sections, and continue to practice repeatedly until you can habitually find the combination of the pedal and the cleat Click, quickly lock the lock, and skillfully remove the lock before proceeding to normal cycling. It is extremely dangerous if you go on the road if you are not proficient!
