1, the cushion is used for "sitting" rather than "leaning"
When the waist angle is low and the legs bear most of the body weight and cushion the vibration, we are floating on the cushion, which is what most people call "leaning". In most cases, the weight of the body is mainly borne by the seat cushion, so we need a soft and elastic silicone seat cushion. We sit on the seat cushion more than lean on it.
2. In order to avoid pressing the perineum, the angle of the cushion should be tilted forward.
When the seat cushion leans forward, the ischium will slide down and the sitting posture will be unstable. At this time, you need your arm to push your body back hard, just like squeezing your body in the middle of the picture. Riding like this for a long time will hurt your opponent and shoulders. This sitting posture reduces the contact surface between the ischium and the seat cushion, increases the pressure, and is more likely to cause butt pain. Moreover, once the center of gravity needs to be changed, for example, when going downhill, the ischium slides downward, the body moves forward, and the hand is supported backwards, which will inhibit the rotation of the hip joint, which is not conducive to manipulation and affects the leg stepping. The correct way is to put the seat cushion flat first, and then adjust it slightly forward or backward according to your riding feeling to find the seat cushion angle that suits you.
3. The silica gel pad with moderate hardness is better.
Most cyclists are leisure cyclists. They need moderate body shape and moderate hardness. Ergonomic considerations are more about health and comfort. Precautions for riding
1. The correct posture should be to bend over, tuck in the abdomen and erect the pelvis, which is conducive to the control of the bicycle and the exertion of the legs, and can also avoid excessive perineal pressure.
2. When pedaling, don't use force when the legs are close to straightness, which will waste the strength of the legs, and more importantly, it will drive the hips to exert force downward and increase the pressure on the perineum and ischium.
3. Occasionally, you can use standing riding during riding to let your hips leave the seat cushion and relieve the blood circulation in the perineum. Or spread the waist straight to relieve the area near the waist and perineum.
4. Ride for 1 ~ 2 hours, get off and rest for 5 ~ 10 minutes, which is helpful for hip blood circulation and relieve pain. Reasonable arrangement of riding intensity to avoid fatigue riding. When the leg strength is not enough, the weight of the body will be borne more by the hips.
When choosing a cushion, you need to know that a good cushion will determine the streamline of the surface and the use of materials according to ergonomics, and can achieve the purpose of comfort without too thick filling layer. A mat with poor design and quality may not be effective even if the filling layer is thick. The filling layer is generally made of foam, and the silica gel filling layer is more comfortable. As early as 1984, sella Italia adopted the patented silica gel filling technology. We can see that the silicone filling layer of its cushion is very thin, which is not obvious by hand.
