    Play-Doh is great for measuring sit bones

    I wanted to measure my sit bones to check into a new saddle. I was wondering how to do it then I remembered I have kids!

    I stole some of their Play-Doh and rolled it on a cutting board. I covered it with some wrap and then sat on it with my naked ass . I simulated some cycling and the results were better than I could hope!



    Measuring from the center to center of the depressions I get 85mm so I'm narrow. That's good as I have narrow saddles on my current bikes

    Holy crap

    great freakin idea.

    I used the side of a box with thick walls. I had to pull down to leave my a$$ print

    I've done the same thing with cookie dough. Wish I would have thought of the plastic wrap though 😜

    Nice idea, I just used foil on a carpeted stair.

    Put a bb in each so they rolled to the center of each depression and measured.

    Remind me never to eat at your houses, nor play with your kids.
    All's well that ends.

    While this is good joke fodder, it is also a brilliant idea! You can easily check it again to see if it is repeatable. I do recommend throwing it away afterwards. I'm going to need a lot of Playdoh.

    I wouldn't worry about throwing it away. Just cover it in cling wrap. Works a treat.

    Your right about being repeatable. I did this a couple of times to double check the measurements. It worked really well.

    Play-Doh is great for measuring sit bones

    That depends on the seat. I like WTB saddles and based on this the Volt in 135 mm is the best. The Rocket in 142 could also work.

    I have a four year old volt that is pretty comfy and I just picked up anew team Volt (Ti). The new one does not feel as comfy yet so I think it needs some break in time.

    Just in case your arse changed size? ;0)

    Very good idea, although it does seem a bit disgusting somehow...

    sometimes the guides are ok, but you have like how it feels. By many guides (WTB, Spec, etc) I should be fine on a 130 or 133 mm. In reality, I hate the 130 mm range. I much prefer 140+. I guess I don't measure to be a fata$$, but in reality, I am one

    I'd be interested in knowing by what definition people rate "comfy". I'm not sure I would rate any of my saddles super comfy, they all feel a bit hard. But, after a 5+ hour ride my bum is not sore and I can still walk. So while I would not sale my saddles are comfy, I think they are probably right for me as they don't kill me...

    OP, you are awesome. Out of all my comfort concerns(the rest I've ironed out) the saddle is the one lingering issue.

    I know off rode we stand more but I ride on paved trails to get to the off rode trails, about half and half. So after roughly 25-30 miles my ass begins to hurt on the long rides.

    Look forward to trying the play doh out and finding a good fit.

    I have long rides also, half paved half trails and I often do have pain in my rear. I can walk fine, but usually if I go to ride the next day I'll be sore.

    I have no idea where to look for saddle as stated in other threads it's hard to beagle to give advice as it's different for everyone
