Message: Big Pelvis on a Bicycle

From: Partialn Sent: 24 Jan. 2006 Message 1 of 6

I found a bicycle race picture where the last two women in the pack have the largest pelveses. The one can sit on her 6.5 inch wide woman's saddle, but the one with a pelvis much much larger has her saddle pushed up between her pinbones.

It just shows that women with a huge pelvis are better a riding big things other than a bicycle. LOL

Wish she were my GF.

Had to paste your picture html into my browser to find it.

Yes, the one in green has a pelvis that appears to measure 1 3/4 times as tall and as wide as the other one in the back of the race. No wonder that her cheeks are closing around her bike saddle and almost hiding it. I can think of better things for a dildo.

You don't see many like this with a Justo Major Pelvis. The girls in the front of them appear to have smaller size pelvises.

Maybe it means that to be a good bike rider you need to have an average or small pelvis. Like you say, the big ones could try riding other things :-)

Now if only she were only into vaginal stretching, something very large could press even deeper between those sit bones (pinbones)!

I wonder if any female members here have had trouble with a woman's bike saddle pressing up between their pinbones?

What the heck is a "pinbone?" I have been a medical transcriptionist for
over 20 years and I have never heard this word, nor can I find it on the
internet.....

Hi, "pinbones" is an everyday lay term for the medical term "ischial tuberosities". It is used by people who don't like medical terms such as farmers and most other people who call the bones where you sit: on: "sit bones" or just pinbones.

The word is also used as a term for certain bones in fish, but not in the pelvic bone sense being used here.

If you want the actual medical transcription term, it is the part of the lower ischial bones of the pelvis that you sit down on, and the term is ischial tuberosities. These ischial tuberosities or sit bones create the side walls of the bone opening of the pelvis and of course limit the size the flesh (vaginal walls and opening muscles) can stretch and open side-to-side as a very maximum size (bone won't stretch).

From a practical standpoint very very few ever stretch that much and usually practice up to a vaginally stretch of about 1/2 to 3/4 inch less than their very maximum (bone opening) -- even with stretching practice. As a hand side to side is about 3.25 to 4 inches and the bone opening on average is about 4.3 to 4.5 inches wide. The female front-to-back bone opening size of the pelvis is on average about 5 inches and is almost always slightly larger than the side-to-side pinbone opening size.

The women who have a Justo Major Pelvis (where the bones are 1 1/2 or more than the average size in every direction) naturally have a potential for more vaginal stretching size.

Such women are rare and only constitute about one in a thousand women so there would only be about 150,000 or less such women with that huge pelvis size in the USA.

If only one in a thousand of those actually practice such stretching, then maybe only 150 (or one in 2,000,000 women in the USA would actually stretch within .5 to .75 inch of their maximum possible size -- and she would be unlikely to be a member of this Group. It is however possible that there may be a couple of female Justo Major size Pelvis members on this size Group.

This big pelvis size is just a "fantasy size" for the very largest sizes of vaginal stretching.

The girl wearing the green suit appears to have the size to fit the 6.5 inch wide bicycle saddle between her sit bones by indenting the fatty soft parts, but of course her vagina would most likely not open -- unless she were into stretching.

Thanks Jim for the info. The word "pinbones" is often used by non-medical people and by agricultural medical sites.

Was looking on the bicycle groups that were discussing bike seats or saddles and they are called the bones "sit bones" there.

On one site, a woman who said she she had a very large pelvis and said she delivered a very large baby with no problems at all. She said that the wide part of her female bicycle saddle would push up and fit deep between what she called her "sit bones" (which are the "pinbones", or her "ischial tuberosities" as they are medically called).

I would think that she must have a true Justo Major Pelvis probably as big or larger than the bicycle rider in the green uniform.
