Sitz Bones "parts"

[Miranda]

I have read many things on here about our sitz bones. I've searched, and think I remember reading something about different "parts" of our sitz bones?

I'm not sure if I'm still hitting my saddle with the right "part" of my sitz bones?

By this I mean, if you look at a diagram of pelvic bones, where our girly bits are, there is a bell shaped curve. I know the sitz bones in this one dimentional pic are are the base of each low point of the curve.

If I am feeling this correctly on my new saddles I'm trying, I think I am still only hitting somewhere just on this inside of this curve... versus the exact tip of the sitz bones? It's pretty close. Maybe it's my riding angle, vs sitting straight up in a chair pressure sensation? btw... I did vary positions between hoods, drops, and slide the saddle forward some too... also riding without chamois for the test spin to not mask the pressure, beside my trunk junk fat

Prior to this I have been riding my pubic bone I figured out with the help of TE. What I feel is definately an improvement from THAT. I honestly don't know what true sitz bones pressure on a bike is suppose to feel like? Pretty sad. Maybe I am indeed on it? Thx for any help!

Miranda- If it feels like you're on the insides of the bell and feels like they're being pulled apart, you're saddle's too narrow. You need the entire sitbones to be supported. Have you measured them versus the saddle width?

[Tuckervill]

If you really want to feel them, sit down on a curb or your front stoop, with your knees up by your chest. Wiggle your tush around a little. Sit there long enough on the concrete and you'll feel them just fine!

That's what you should be sitting on. I think someone said you can measure the width of them by putting a playdough pancake there on the stoop before you sit down, then get up carefully and measure the distance between them. if they're wider than that saddle, the saddle is too narrow.

Thx for the help thus far...

Well, crud...

I think all 5 of the saddles are too narrow. I ordered: Specialized Ruby & Jett 155mm, Terry's Butterfly, Zero, Falcon.

I did measure myself pre-buy per TE instructions in some Pilsbury pie crust dough on a step stool. Got measured at 2 lbs, one in Bontrager's color seat thingy, and Specialized butt-o-meter. I was 140mm dead center sitz bones in the Specialized seat. They said I could go with a 143 or 155, but encouraged the 143. I thought better of the 143 as the saddle sides slope slightly, and narrows it (and as I read on TE).

Once there was a thread about who we liked on TE and why. I didn't reply as I could not say one person. My answer would be all. No one has ever made me feel dumb or ashmed with anything. So, here's some sorta gross-ish info and where I think the saddles hit...

I got in the buff in front of the full length mirror and did my best impression of the circus flexy girl bending over. The red pressure marks I saw were parallel across from about where a lady gets a 3rd degree (all the way thru) tear repair towards the back of the vaginal opening if you had a really big baby. My 'little' darlings were both pushing 10 pounds. Glad the docs don't charge by the stitch. Anyrate... that is just barely inside that bell shaped curve I believe. When I pressed on the bones from the red marks backwards, I think the proper spot is slightly behind it.

I did order and send back a Titanico without riding it (not off TE). It was wide, but the color was defective. They didn't want to take it back (even after seeing the defect in pics emailed of how it arrived). When I insisited that I was not happy with trying to break in a defective saddle, that man had a little tantrum and told me to take my business elsewhere. I really wanted to tell him some other things, but I held my tounge in fear of not getting my money back.

So, guess I'll go back through some wide sitz bones threads and look again. Sorry for the rambling... I'm just getting depressed about the saddle hunt *sigh*.

My opinion is that if your sit bones are 140mm apart, then a 143mm saddle is still going to be too narrow- your bones would still be on the saddle frame edges.
Would you consider an unpadded Brooks leather saddle? Or did you already try one and find it not suitable?
I have VERY wide sitbones and the Brooks B68 is the only saddle wide enough for me (210mm). It's very comfortable for me, even on long rides of over 50 miles. The Brooks B17 is 170mm in back.

P.S. I would *not* recommend the Brooks "S" models however. Supposed to be for women, many women (including myself) find them way too short in length.

It seems that if your sit bones are 140mm apart you should be fine on a 155. Did you try those already and they didn't work for you? (I couldn't tell from your previous post if you'd tried them or if you had them on order). I don't know why a store would push a 143 for you; that's clearly too small.

Also, when you ride are you in a more upright position, or are you more folded over? I ride more folded over, especially in the drops (my seat is about 3 inches higher than my bars), and I find that I do feel more pressure on the inside of my sit bones, but I know my saddle is wide enough b/c both sit bones are dead on it with space all the way around - I can feel them pretty well and I've checked, numerous times. I had trouble at first and thought that my saddle was too narrow, but I stuck with it and let my pelvic muscles strengthen and now I'm pain free.

No, I have not tried a Brooks, yet. Thx for that link. I have read much about them here on TE. It seems like for ladies wider, it's one of the few options. I like that the B68 comes in silver rivets. I wish the other did. But, at this point, that is the least of my concern. If my rear end can spend more time on the saddle, then who cares as it won't be seen sitting idle without a rider.
