Not all cyclists are the same; the professionals we see running in international competitions have a weight and body composition that can hardly be found in amateurs. Pros follow nutritional and training tables defined by experts and doctors that lead them to have a well-defined race weight. Their BMI, in other words, the ratio of height to weight, is constantly monitored and based on their needs. But how to choose a saddle based on your body weight?
The BMI also called the "Body max Index" is the ratio of the weight to the square root of the athlete's height. It is generally the indicator of the body shape and health, but in the choice of the ideal saddle it allows you to predict the pressure value that will be exerted. In fact, knowing the height as well as the weight is useful to understand the distribution of forces. For example, a rider of 80kg and 170cm tall will distribute the load differently than an athlete of the same weight but with different heights.
The average rule is that the more BMI increases, the more useful it is to have a wider saddle that allows the pressure exerted to be well distributed. It is wrong to think that more weight means having more padding on the seating area: this is a subjective value that depends on the rider's experience and his/her subjective tastes.
The ergonomic saddles are able to adapt and respond to different BMI. For users who looking for maximum comfort and resistance, the "Space" versions, wider and more padded, are the perfect product.
In the choice of the saddle, there are various factors to consider: experience, habits, riding style and use. The BMI is certainly an outstanding value.
