Measuring sit bones--is my yoga mat defective?

Several TE'ers have complained about the Jett being too hard. I love my Specialized Avatar saddle. I noticed you said 130mm. Many people average 145mm so is there a chance you could borrow one in that width and give it a whirl? Just to see? As for the Terry saddle, many of her saddles come in a pear shape. Even though it may be the right width, it may be the wrong shape for you. I always had pain on the inside of my sit bones with her saddles. I guess the saddle sloped too much and I need a flatter type saddle--hence the Avatar.

Well, I'm beginning to wonder if my saddle is not too narrow as well, now... Where, exactly, are your sit bones supposed to rest on the saddle? How close to the medial line? :p

When I got measured for my saddle at the LBS where I purchased my bike (I have since decided they do not fit my needs in terms of knowledge, effectiveness, and friendliness), I sat on the butt-o-meter and the guy grabbed that thing from under me so fast once I got up, I couldnt' believe it! :confused: He tilted it so I could not see it and fiddled with it for a while before he told me he thought I was a 130. Now, if I am "between" sizes on my measurement, is it better to go a size up?

If any of you TE'ers could spare a T-shaped 143 saddle, I will pay the shipping to me and back to you! (If you want it back)

I will definitely look into a 143 :p I browsed through so many other saddle threads and I saw that there are supposed to be about 1cm in each side of your sit bone measurement?

I cannot tell you how much this input helps me. Saddle searching is so difficult to begin with that having the wrong width just complicates things. It is so frustrating when bicycle salesmen (it was the owner who was helping me.....:mad:) think it's okay to sell you things that you don't need or that are wrong for you.

sigh

The search for a saddle continues... I would loooove to find one of those that "disappears" while I ride! That would be a dream! :D

Here is a picture of the Jett. I think my sitbones hit the saddle at the pink circles: not exactly in the middle of the seamed space but a little towards the outside.

Ana,
I would guess that as long as your sit-bones are on the padded parts and not on the hard edges, it would be a good size. Saddles are made for a range of sizes, hence the generous padded areas. The next larger size may be too big and interfere with pedaling motion. But as we all know, there is more to comfort than fit. I could not get the Jett saddle comfortable no matter what I did. I raised the nose, lowered the nose, double checked the fore-aft and seat height; I ended up frustrated with it and ditched it for an Aspide Glamor. Sometimes the extra padding is just not comfortable. I think it was just not supporting me properly. The Aspide Glamor has no cutout and is thinly padded and you would think it would be painful looking at it. But for me, it was fine, but a little flexy so I kept looking

I have since bought a Bontrager saddle (they have a 90 day unconditional return so I thought 'what the heck'). They have several models, and I went with the RXL, which again has no cutout, thin padding, and has firm support (carbon shell). It does not look as comfortable as the Jet, but it is night and day for me- When I die, I am going to be buried with that saddle!

Yes, your sit bones is where most of your weight SHOULD be.
Look, I didn't ride all winter. Yesterday I finally got in a 20 mile ride to start the year off. Today my sitbones are really really sore. That's totally normal. As I get in another dozen rides or so the soreness will be all gone for the year and I'll ride several thousand miles with no sit bone pain and no soft tissue pain at all. I ride on a pretty hard unpadded Brooks leather saddle that is basically designed to support my weight on the sitbones.

If you are used to only being on padded cushy foam/gel seats and padded chairs, then your sitbones are going to hurt the first time you actually put all your weight on them...and they'll be plenty sore for days afterwards. But they'll adapt as you keep riding and then they likely won't hurt anymore. Having your weight on your sit bones prevents painful soft tissue pressure.

Riding on your soft tissue areas and not on your sitbones is very painful and can lead to nerve damage. But unlike your sitbones, your soft tissue cannot adapt to bearing weight, and will simply continue to hurt and/or become numb with nerve damage.

Thank you for all of your input!! :D Sharing your experience is invaluable! :)

What about the Jett did not work out for you? Did you have similar intense sit bone pain?

Hm...maybe I will stop by my Trek LBS :) Is it one of the new Inform models I've seen a couple threads discuss?

Thanks, this is very encouraging! :D I will try to hold out for a dozen rides (it seems like so many :p) and try to break it in :)

I wish the bicycle stores were more attentive to saddles upon selling a bike... :p Perhaps it would make all this saddle searching less painful.

I'll agree that sit bone pain is normal until you break in your backside - but your description of excruciating pain after 20 min doesn't sound like normal sit bone soreness.....

It's been a while that I've been off the bike long enough, but what I remember is being on the saddle wasn't painful, what hurt was getting back on the day after or after a break - it would hurt for a few minutes and then that hurt would go away. Like breaking in a new pair of shoes.

btw - I have a several Jetts. One came on my race bike and I like it so much that I bought one for my rain bike - but everyone is a bit different, so what works for one person may not work for the next - keep trying. I think I'll go with the S works when these wear out - same shape, but thinner and lighter.

"excruciating" means different things to different people.
The substantial sitbone soreness I'm feeling today might possibly be called excruciating by someone else. I'm cringing every time I sit down today. :cool: I'll live.

I've had a lot more sitbone pain than that- but even the worst has always faded away completely after a week or two of regular riding. I guess we are all different- differently 'padded' behinds, different saddles, angles, etc.
I used to own a horse when i was young and rode all the time for hours. Now when I go for years without riding and then suddenly ride one day- I feel excruciatingly sore and painful both during and after the ride. One time I truly didn't think I could unmount and hit the ground standing because of the pain....but I did. I had to retreat to a bed for hours afterwards. :(

For measuring, I have a much simpler method assuming you have reasonable flexibility.

Get a tape measure (a flexible fabric or paper one), and lie on your back on the floor. Flip your legs into the air (towards your head) and feel around for your sit bones. When you locate them, measure them with the tape measure holding it with your thumbs marking the location of each bone. Then, without letting go, put your legs through your arms so that you can veiw the tape measure in front of you. Voila!

My sit bone measurement is 133. When I sat on the butt-o-meter, all they told me was that I needed a Specialized 143 saddle. No other information, which wasn't very helpful when looking at other brands! I tend to favor men's saddles. So far, I've been successfully using the Terry Fly, but because of the padding, it does get softer over time and needs replacing. Luckily, as far as saddles go, it's not that expensive. I need to replace it about every 3000 miles or so. I may have an extra one lying around, and if so, I'd be happy to let you try it out. I'm still searching for the perfect saddle which for me would pretty much be a Fly with minimal padding.

I went to the press the flexible tape measure against the bones school too. One hand on each side and don't let go before reading the measurement.

Ana,
Yea the saddle is one of the new Inform ones, and I had seen it several times at the LBS before a crash damaged my Aspide and I had to buy a new saddle. At first, I looked at the WSD ones, which had more padding than I wanted. Then I noticed the RXL (Unisex) came in wide 154 (my sit bones measure 144)...

I had gone the padded route previously, with a Terry Butterfly TI, and it was ok till the padding 'broke in' and I just sank into the thing and it became painful. Then I found the Aspide Glamor, which felt ok, and I realized that padding is not for me; I want support. No holes, no Gel. I want my weight distributed evenly over the thing so I don't get pressure in any one spot.

The Jett just plain hurt. My sit bones hurt all the time. If I hit a bump, it hurt more. The longer I rode, the more it hurt till I was thrilled that the ride was over. Even my Terry was more comfortable. I read about the Aspide Glamor here, and bought one. One ride - no pain - and I realized that it was not my sit bones that were the problem, it was the Jett. To be fair, while I don't know what size it was, I am certain it was in the 140's and was too small. But I had ridden mens saddles for years without that kind of pain.

Yes, your sit-bones may need to get used to the saddle if you have been off the bike for some time, but you should see improvement over time as you put the rides in. If you don't then maybe the saddle isn't a good match.
