Saddle height? Inseam minus 10cm?

so that doesn't take into account BB height, crank length or type of shoes/pedals.
i use my tumescent member as a guide. this has to be done totally naked at sea level and with a heamacrit level between 55 and 60.

being that the equation is based on inseam measurement, as gives you the height from the bb, bb heigh is irrelevant. given that crank length will only vary by about 10mm, and that is it only a guide, crank length doesn't really matter.

it is not meant as a perfect "make sure your saddle is this high to the nanometre" just as a starting point.
