This gracious and little knightly buffalo that concerns the fair sex is the classic example of how you can completely misjudge the assessments if you do not perform a thorough examination and multi directional.
In fact, the error arises from the anatomical observation of the male and female pelvis not contextualized in the body of the person whose pelvis is an integral part.
To clarify this concept once and for all, it is necessary to divide the explanation into two parts.
Without any shadow of doubt the shape of the female pelvis is different from the male, for the reasons that everyone knows: the conformation and position of the external genitalia and in particular to allow women to carry the unborn child and then to give it to light in a natural way.
Regarding the cycling area we can observe that the contact zone, in particular the pubic area and the two large ischial tuberosities present some differences.
In man the ischial arch is narrower at the base and with a very pronounced vault height. In women, however, the ischial arch is lower and with a more open base.
This different morphological aspect has led many illustrious figures of the cycling world to claim that women had a distance of the ischial bones greater than that of men, but all this is true only if the two basins, the male and female basins were of the same size .
However, given that more than 70% of women (especially those who practice cycling) the average body size and consequently that of the pelvis is significantly lower than the male average, it results that the average distance between the two ischial tuberosities of women is not wider of that of men.
A study conducted on a multiethnic cycling population sample of 49,785 people divided between males and females showed that the highest percentage of male subjects recorded a distance of the ischial bones of 121 mm. 24% of all men, while 24% of women showed a value of 111 mm.
If you slightly widen the scissors, you can see that 61% of men have a value between 116 and 126 mm. while 60% of women are between 106 and 116 mm.
It’s up to you to figure out how things really are …
