sit bone distance=what saddle size?

[KnottedYet]

I just ordered a B67 Brooks. Love the idea of a 210 width. My Serfas is 180 width, which is just about the width of my sit bones. (outside edge to outside edge) So yes, each of my sitz is on the saddle, but only just barely. Not centered in the "middle" of each side of the saddle by a long shot! (a whole lot better than what my bike came with, however!) I ordered from www.wallbike.com and they give a 6 month trial period. I had a nice conversation with Bill, the owner. I was torn between 2 different saddles: B67 and B72. He told me to try one, and if I didn't love it to send it back and he'd send me the other.

gotta love a 6 month trial period!

My boss the bike goddess was appalled that I'd ordered a Brooks. But she has NO BUTT and little snake hips, so she has no idea what the wide-sitz folks have to deal with!

I read an article that was posted on this site somewhere about saddle fit...and the basic rule was that your saddle should be at least as wide as the middle of your sit bones.

So if your middle to middle distance was 158mm your saddle needs to be at least this wide to properly support you. The reason for this is that if your saddle fits in between your sit bones, all the pressure will be on your soft tissue and pelvis and after extended periods of sitting, it could cut blood flow to important areas (there are key arteries and nerves running along our thighs between the sit bones).

I have the reverse problem...my sit bones measure narrower than 140mm and most of the 'women's specific' saddles are way too wide for me (my legs rub too much).

Another point of note: 158mm = approximately 6 1/4 inches. I believe that there are quite a few ladies Terry saddles that make this measurement.

Am I weird or did I measure it wrong? I seem to have sit bones that measure only 4" point to point??? That's only about 102 mm....

I'm pretty fat, and not sure if I could find my sit bones. Trust me, it's one fat bottom.

When I was reading up on this a while back, I read a suggestion for finding your sit bones. Put your hands on the chair palm up and then sit on them...and you'll feel them.

Also, when I was looking at the Specialized fit kit thingy at the LBS, it showed that you should sit on it with your knees at more than a 90 degree angle. As in, sit on something low so your knees are nearer your chest. (A curb or stairs would probably work.) This will give your sit bones more prominence, I think. I also saw it suggested that you can use a sheet of carbon paper face down on a sheet of white paper. The Play-Do idea was a good one, too.

Yes, I was wondering if my sit bones could be found the first time I saw that Specialized pad...but my bike seat finds them every time. I probably should think about a new saddle, too.

Boy that doesn't sound right! why don't you try what some of the others have done?

If you go to Specialized dealer, they'll measure it for free. Then there will be no guess-factor involved.

This thread has been so helpful to me. I finally realized I'm not sitting far enough back on my saddle. I'm skootching forward. So I need to do a little adjusting.

Thanks all,
