    Only if your sit bones are as well padded as mine!!

    Seriously though- my workstudy student ( a lovely young man, who rides
    a cobalt blue Specializied Allez) had just earlier measured his sit bones in
    order to shop for a new seat. He started with the find your bones & use
    a tape measure method. He then tried the methods listed on the thread--he had a little trouble with the sit on concrete- (his sit bones are not as well padded.) He then successfully measured again using 2 markers----line up a marker on each bone- then lean/sit on a piece of paper. He was pleased
    with this measurement.

    I'm trying to figure this out ... ? He does what with the markers? (Are you talking felt tip markers?)

    If you go to a bike shop and sit on one of their measuring devices, is that the most accurate? I have this image of me putting my well-padded bum down on it and leaving behind nothing but a smooth surface with a ridge where my crack is, sigh.

    ETA: When I tried the "sit on a curb" method, I ended up with a piece of paper that was dimpled/pimpled with little indentations where the rough concrete had almost pierced it, in two roundish circles, but no clear definition where the bones were.

    measure from center to center of the indents, but imagine if you will, a bike
    saddle. you'd want it to support a little of the area around it too.

    I have got to say that measuring sit bones is one of the silliest things i've ever had to talk about (well, there's queefing)

    I am a bony butt, so i decided i had to check with someone who isn't; so chose
    my husband... can i find your sitting bones? please come sit on my hands.
    he squealed and yelled OW! (he'd just ridden 50 miles) he said
    "YOU GOOSED ME!"

    the result of my scientific test was that i didn't have enough time to really
    check... before he jumped away.
    And i can't very well go up to strangers and ask them!

    sit bone measurement try #1

    Okay from the best I can tell using a quad-folded paper towel (cheap brand!) on a hard chair, It looks like center to center is somewhere around 5 1/4 inches or 135 mm (hopefully that equates?)

    So I went to a bike catalog thinking I'd start seeing measurements to compare to . . . but none had it!
    Jeez,
    Anyway, thanks for the hlep out there
    If this measurement means anything as far as a "good size seat" let me know

    LOL - too funny.

    A neat trick to puzzle out the "center" of your sit bone divets on your buttOmeter surface... roll a ball bearing (...or marble, etc.) into the hollow and they will find the center. I used my memory foam pillow (sans pillow "slip" so the ball wasn't sitting on a trampoline), and I got the same readings within 1mm 3 times! Now if only I could translate that to my Secret Saddle.

    But being a true dirt fiend, I'm still uncertain how the plethora of road saddles are applicable to trail use. Or not. For all the trouble saddle makers go to for different features, they don't bother to let you know what they are for... ("we specialize in ALL makes and models...")

    My old Serfas Arroyo was comfy on the longest rides until the last year when I got out of shape due to less training. I wonder how much one's sit bones can change over the years?

    Wow...what a great idea! I never thought of doing that. I have a memory foam pillow, but it's one of those "contour" pillows that supports the neck...I wonder if I flipped it over to the "flat" side of it, if I could get an accurate measurement. I think I'll give it a try just for kicks.
