The Perineum - Male bike fitters need to know. An area of concern!




The above model is the pressure contact points of a saddle for a female.

The above is the male contact points on that same saddle.


Too many male fitters tell the gals how to ride, and how to sit on the saddle by their own feelings. I can't think of the last time I have seen a guy give childbirth even if they did have something to do with it.

No wonder so many gals come to us with an ouch!

The perineum refers to the area of the trunk between the thighs and the buttocks. The pelvis is limited inferiorly by the pelvic outlet, the inferior pelvic aperture, which is bounded anteriorly by the pubic symphysis and posteriorly by the coccyx.

There seems to be many who think this area of the body doesn't come in many shapes and sizes.
In fact their fit ideas don't take a precision measruement?

Then you have the comparison of male and female and its the subpubic angle adn pubic arch that can't be on the outer side of the leg by video and some short of leds?

The man pelvis is heaver & thicker than a female pelvis and has more prominent bone markings. In contrast, the female pelvis is wider, shallower, and has a larger outlet.

The diameter of the lesser pelvis is key not just for childbirth, but how you need a correct pelvic examination. We measure that and that makes a difference.

There is no reason to have an ouch because of a very misleading bike fit!
