After a day of riding, the discomfort and pain that the cushion brings to you is inevitable. Like the maxim, NoPain, NoGain. But fatigue and injury are different, and potential pain may bring more health problems in the future. A sub-bike riding friends body size, whether the size of the frame, seat height, seat longitudinal position, the vertical length of the horizontal can cause varying degrees of damage to the rider. The slightest hazard is the uncomfortable riding experience, and the heaviest hazard will even make you say goodbye to the bike. However, in the eyes of Sky Team technical consultant PhilBurt , the problem of unscientific vehicle size causing the rider's physical discomfort is easy to find and solve. Burt is an expert in BikeFitting and has written a book devoted to vehicle size and driver performance and damage. Below, Burt will explain some of the typical symptoms caused by vehicle size issues. 1, the soles of the feet and ankles Your feet are the two most important points of contact with your bike. Burt believes that many factors in the size of the car will affect the comfort of the feet and ankles, which is difficult to explain clearly. The position of the lock shoe lock is undoubtedly an important factor in the pain of the foot, and the height of the seat cushion also affects the comfort of the foot. When the seat cushion is too high and the crank reaches the bottom, even if the leg is straightened, the foot still cannot touch the foot naturally. It can only compensate for the foot, so that during the riding process, the ankle increases the amount of exercise, which is bound to cause fatigue. If the seat cushion is too low, it will increase the amount of activity of the ankle, which may cause fatigue or damage. Burt believes that the foot has a greater probability of injury than the ankle. The lock shoes are not suitable, the position of the lock piece is offset, and the seat cushion is too high may affect the comfort of the foot. Burt pointed out that some people didn't realize that their lock shoe locks were too far in front, so that the toes were too tired. Fine-tuning the locks back allows the pedaling pressure to spread over the entire foot, which makes the ride more comfortable. Burt shared his tuning experience: the correct locking position can be achieved by aligning the pedal axis with the first and fifth shins of the foot. The walking posture also affects the position of the locking piece. If you are "outer character", your foot should also correspond to this posture when riding. 2, knee The bicycle is a four-bar linkage from the side. The thigh and the lower leg respectively play the rocker and the connecting rod, and the connecting point of the rocker and the connecting rod carries a great impact and wear during the riding, but There are also many factors that exacerbate these shocks and injuries. The front and rear position of the seat cushion, the front and rear position of the locking piece, the height of the seat and the length of the frame may affect the working condition and comfort of the knee. Everyone may know that cycling can promote the recovery of knee injuries, but a large number of people have injured their knees because of cycling. At the same time, knee injuries caused by body-to-sports sports such as rugby are different because of knee injuries caused by cycling. Burt pointed out that the knee pain caused by riding is derived from the patellofemoral joint, and the pressure from riding is applied here. The cushion is too low, or the cushion is too forward, which can exacerbate knee damage. It is very simple to judge whether the knee injury is caused by the size of the frame. If it is a size problem, the knee will be painful after riding the car, instead of the size problem, the knee injury will make you feel obvious discomfort every time you step on the pedal. . The discomfort at the front of the knee is most likely due to the length of the crank being too long, or the height of the seat cushion being too low, or because the seat cushion is too far forward or even the locking tab is too far forward. Pain in the middle or outside of the knee results from the deviation of the seat height and the angle of the locking tab. The vertical distance between the feet also affects the comfort of the knee. The discomfort in the back of the knee comes from the height of the seat cushion , or the position of the seat cushion that is too far behind. It is also possible that the shape of the seat cushion is too bad for the pelvic activity. 3, lower back The factor that affects the comfort of the back is only one cushion position. Another extreme situation is that your seat cushion is too low, so your back is so straight that all the impact on the road runs to the lower back. Burt also said that some unscientific riding postures can also cause back discomfort. For example, some road bike enthusiasts hold the same position of the handlebar from beginning to end, which is obviously not conducive to the relief of lower back fatigue. 4, neck and shoulders Cyclists have experienced neck pain and shoulder pain. So we need to properly relieve their pain. The pain in the neck is likely to be too long to look at the road for too long, and reducing the degree of head lifting can alleviate the pain. The method is very simple, and the height of the handlebar is raised appropriately. 5, hands and arms The stack and Reach of the frame will also affect the arm, too low Stack and too long Reach can also make the arm feel tired. Keeping your straight arm always keeps your body away from the handlebars, and it also puts too much pressure on the biceps. If the arm is slightly bent, it can effectively slow down the arm. Burt pointed out that some newcomers are very tired after long-distance riding because they have not learned to adjust their posture during riding. They don't know that they can relieve fatigue and damage by changing their riding posture because they don't adapt to other riding postures. The arm should not feel uncomfortable during the ride. If you have this feeling, it means that your car has a problem with the size. The numbness of your fingers is sometimes not due to physical decline or low temperatures, but it is likely that you are riding a bicycle of a size problem, or your riding posture is not correct. If you apply too much pressure on the handlebars, your double gestures will be more numb. The drop in the handlebar is too large, the length of the frame is too long, and the length of the handlebar is too long or too short may cause numbness of the hand. Take the road bike as an example. Your handlebar should be the same width as your shoulder, specifically the width of your shoulder. Female riders have shorter shoulders, so shorter handlebars are needed, and most handlebars are too long. A too narrow handlebar will reduce the sense of handling and cause more fatigue. Beauty scissors can be used to trim eyebrows and nose hair. First, prepare an eyebrow scissors and an eyebrow comb. First use the eyebrow comb to comb the eyebrows down in the same direction. With one hand, use an eyebrow comb to gently comb the end of the eyebrows, and stay at the place where the eyebrows are too long, while the other hand uses an eyebrow scissor to gently cut off the length of the excess eyebrows beyond the eyebrow comb. Pay attention to the repair process from the end of the eyebrow to the direction of the brow. When trimming to the brow, the wrist can be slightly bent, and the tip of the eyebrow scissors can be used to repair, so that the trimmed eyebrows and brows are more flexible until the desired arc is trimmed.
