    Cheek-to-Cheek measuring tool

    To disable ads, please log-in.

    Has anyone used this at-home sit bone measuring kit? I just ordered one, for the heck of it. I've been measured at my Trek store using their Bontrager butt measuring device...but I guess I'm skeptical of just one opinion. I'm curious to see if I end up measuring the same (150mm), with this home kit -

    It's a bit pricey with the shipping charges, so I'm hoping it will be worth the money.

    I tried the bontrager one and didn't like it either. The Specialized version I believe is more accurate.

    I just used the sit on a paper towel method of measuring sit bones. It works pretty well.

    Good to know. I may have to break down and visit my local Specialized dealer (I don't particularly like this LBS) to get measured.

    Ok, I'm sure it's explained in some other thread here...but could you spare me the hassle of trying to find it, and provide details on how this method works? Do you sit bare butt on the towel? Or in clothing? On a hard surface? I'm confused...

    3rd postdown.

    I tried it a couple of different ways... on carpet & on a hard wooden chair/bench. different paper towel of course. sit on the paper towel and then I kinda pulled my knees up.

    when you get off the papertowel there's going to be 2 impressions where your sit bones are - measure the distance in between those.

    If that's in the ballpark of what the bontrager fit kit told you, then you've got confirmation.

    I need something squishy in between my butt and the hard surface, otherwise my butt is too squishy all by itself to make an impression.

    A yoga mat works, or just a terry towel or blanket, folded in two or three, should. I used typing paper. Easier to make an impression on stiffer paper, plus it lasts longer.

    The important things are (1) the underlying surface is hard and flat and (2) you're bent at the hip to approximate your riding position.

    Once I made my butt-print, I circled the impressions on the paper (rather than a number, I had two ovals that aren't completely parallel), and took the paper saddle shopping with me. Easy to see which ones would support my sit bones and which ones wouldn't.

    Thank you both!!! I will try this method when I get home today. How long does one need to sit on the paper before an adequate impression is made?

    Oakleaf...in regards to the "bent at the hips" statement...I'm wondering if perhaps doing this on say...a kitchen counter, would allow me to bend forward sufficiently to simulate my riding position...any thoughts on that?

    And after reading through that entire thread on sit bone measuring...I still could not find any reference as to whether you should be bare butt or clothed while doing this. Anyone care to tackle that one? LOL

    OK, I tried this way back when and was never sure about the measurement part. Do you measure from the center of each sit bone impression or from the inner edge or outer edge?

    Kitchen counter should be fine - feet on a chair or drawer, elbows on thighs approximately. Wear something that won't get in the way of an impression. No jeans, nothing bulky, anything else should be fine. If it doesn't print, try again!

    Reading the title of this thread, I heard Fred Astaire's voice in my head.

    BTW I really like the idea of drawing circles on the sit bone impressions and bringing that to the store with you.

    The topic title looks like measuring the width..of a smile.

    Paper towel technique is a great tip!
