    Saddle & sit bone measurement

    Need to start looking for a new saddle soon, anyone know of companies that give good sit bone support. Or do any provide sit bone measurements?

    you have to have your sit bones measured, then find a seat thats a little bigger.

    I haven't seen that one yet, thanks, lots of good info in there.

    I've measured myself, but from the few saddles I've looked at so far (need to look more tonight) I haven't seen any companies that give the measurement. I guess it's not common?

    Bontrager/Trek has a sitting bench with gel in it that you can get the size of saddle they suggest. I don't think it actually gives a sit-bone measurement, just their corresponding saddle size to use. You could of course measure that. The Bontrager saddles that work with their suggestions are the inForm saddles.

    To get your sit-bone measurement at home you might be able to try play-doe in a large zip-lock bag. Just a thought, haven't tried it.

    Edit: Doh, didn't see that you already measured, skip the last suggestion. I don't know of any companies that match your sit-bone measurement with their particular saddle width for correct support.

    Most any Specialized LBS Dealer has a sit bone measuring board, and measures for saddle width.

    WTB, Trek, and Specialized do give their saddle widths:

    I'm sure there are more. good luck!

    Sounds like what you can do is like the above video said in it. Know your sit bone width, get a saddle that is a little wider that does not have too much of a sloping wing edge, and has a slight uprise in the tail for good forward rotation of the pelvis.

    I knew from Bontrager's saddle measuring bench that I should use a 146mm (middle size) in their road saddles. I contacted Bontrager about their mountain saddles and they said I should again take the middle size which was the 138mm. I ended up, on one of my bikes, with the 143mm Specialized Phenom since their 130mm would obviously be too narrow. It has worked out very well for myself.

    deerhill, unless you are looking for a really high-end saddle like brooks, selle italia, etc. you should do one of two things...
    -buy from the lbs that has a saddle demo program. WTB comes to mind.
    -buy from Specialized or Performance so you can return/exchange the saddle if it doesn't fit.Trek may also offer the same service.
    -Just don't try to buy your saddle online until you find one that works for you by riding it first.

    Didn't know they were exchangeable. I should have been doing this when I demoed my bikes.

    also, try tilting the tip of your seat down a hair so its not level. a level seat usually just kills my perineum

    bringing back an old thread cause i was curious about the same thing and my new saddle hurts my backside worse than my old one. i ended up using a piece of a styrofoam cooler i had from an outing last week, put it on my coffee table and leaned forward into my normal riding position. and just kinda sat like that for a few mins. got up and voila perfect sit bone dents. dug though my pile of leftover bikes and found one that almost fits like the video( https://www.youtube.com/watch?v=CucL...eature=related ) said it should gonna use that one til i buy a new one.

    i used one of these assometers at a Spesh dealer when i got my saddle. it worked great. turns out, my WTB seat was too narrow. the Spesh seat feels a lot better

    So newer saddles provide a sit bone measurement now?

    That's weird. I thought an 'assometer' was used to measure attitudes. Oh well, what do I know.

    I sold Trek saddles using the gel measurement device for years, and it works very well. Measures the sit bones, and then that measurement falls within their parameters for 3 different widths offered in primarily their road and mountain bike saddle lines. I have also used this for my own personal saddle purchases and it hasn't failed me yet.

    Although, I have been said to be a bit of a hard-a$$, so maybe it wouldn't matter which saddle I used.

    When i bought my WTB Volt the guy @ the shop gave me a simplified breakdown

    135mm saddle for 30" waist or lower
    142mm for 32-34"
    150mm for 36"+

    Coming from a medical background and knowing anatomy, this is a HORRIBLE analogy. your waist has absolutely zero to do with your sit bones. If you lose weight...your sit bones don't move.

    Very true!

    As a follow up to the original concern, I never knew what I was missing until I did the Trek / Bontrager measuring thing. I showed up as blue, bought a blue saddle and have loved it ever since.

    . This is why bike shop employees don't make good medical professionals.

    Hell.. SQ Lab has a kit that they mail out to you and you can get your sit measurement fairly easily. Outside of that I am seeing more and more shops have the Ergon measuring tool/bench and that will provide you with your measurement.
