⭐Expand the contact area between the buttocks and the seat cushion, disperse the pressure, and reduce the pressure on the buttocks.
⭐Thick padding can absorb more shock and vibration from the frame.
In fact, a wide, thick saddle doesn't necessarily reduce hip pain. Let's take a look at the causes of butt pain first:
1. Compression: When sitting on the cushion, the weight of the body is pressed on the small area of the cushion, which will generate a very large pressure, which will compress the capillaries and affect the blood circulation.
2. Shearing force and friction: When pedaling, the human body will slightly sway from side to side on the seat cushion, rubbing the edge of the seat cushion, causing friction, friction and heat, which will soon lead to pain and skin damage. The shear force generated by friction with the seat cushion combined with the action of compression further aggravates the blood circulation disorder.
3. Moisture: The moisture brought by sweat aggravates the effect of shearing force.
4. Temperature: When riding, the skin temperature, especially the temperature of the perineum, will rise significantly. The increase in temperature accelerates the metabolism of the skin, and the blood circulation is blocked again under the action of compression and shearing force. At this time, the skin begins to necrosis because it cannot obtain sufficient nutrients.
Obviously, the wide and thick seat cushion has an advantage in compression. But a wide and thick seat cushion will bring more frictional shearing force. The wide and thick seat cushion is not easy to perspirate and is more humid. A wide and thick seat cushion will make the butt warmer.
Of course, compression is the main reason for the pain in the buttocks, and a wide and thick seat will bring comfort, but because of the unfavorable factors of the last three items, we also know that a wide and thick seat cushion does not always make us feel comfortable. The benefits of the first item can be felt when you sit on it, but the longer the riding time, the greater the adverse effects of the last three items. That's why some saddles are comfortable to sit on, but can be a pain for us over long rides.
We all know that sitting on a sofa is not a comfortable high-end sofa with thicker and softer filling layers. Its hardness and filling thickness are carefully designed, and sofas that are too soft are often relatively low-priced products. , it is uncomfortable to sit for a long time.
The same is true for the seat cushion. The seat cushion is very comfortable and soft at first, but it may cause you pain after riding for a while. The filling foam of the seat cushion is divided into good and bad materials, and the same material has different densities. A good seat cushion will be considered as a good filling material, with a moderate density, or even layered filling. The upper layer is lower density, and the lower layer is made of high-density material, so that it will have a more comfortable touch without being too concave.
At the same time, after we sit on the seat cushion, the seat bones sag, and the edge part is easy to bulge and compress to other places. The shape design of the seat cushion is also very important.
Therefore, we have to be selective in choosing a wide and thick seat cushion, look at its design and workmanship, consult the riders who have used it, and do not blindly pursue a wide and thick seat.
