Sitbones measured

[Susan]

@bismarckgimpy: KnottedYets post makes total sense to me and is something to hold onto right now

The Problem is, there is a lot of information out there and the different saddle brands don't seem to agree at how to fit a saddle at all.

If I measure my 155 mm SLR (that I will send back today) with Knotted Yets Post in mind (and hoping I'm doing it right) I would say that it is designed for a woman with approximately 130mm - 140mm outside-to-outside width and 110mm - 120mm center-to-center. (And, just in case somebody wants to know, at the point where your sitbones hit, the cutout measures about 35mm.) With this measurements there still wouldn't be much wiggle room for shifting around and so on. That's small for a designated womans saddle, isn't it?

If you read the SQlabs homepage, they measure center-to-center and then add some centimeters depending on your position on the bike. For SQ-lab I would need a 155 oder 160 saddle - but then my sitbones would still stick out a bit as they measure 170mm from outside to outside.

Specialized would fit me on a 155 saddle.

But I think you are totally right Bismarckgimpy, wide saddles just don't have a positive Image that could be why they are not promoted and sold so much. It may be a similar problem as with Bra-sizes (where "everyone" fits a B or a C...) but thats a whole different story

@Muirenn: I will definitely try a Specialized womens saddle too. I have the one that came with my Stumpjumper, but as it is a mans-model (I don't know how you really call that? male model? He-bike? ) it is too small.

I think there is a SLR without a cutout, do you mean that one? Mine is the one with cutout (SLR lady gel flow) and it is definitely wider than the Diva-cutout, though not as wide as it looks on the pictures (on the widest part, the cutout measures 40mm, at the point where the centers of your sitbones hit it measures about 35mm).
The SLR is harder than the Diva and the shape is a bit different - the diva is rounder on the top, while the SLR is quite flat. The effective width is approximately the same.

I have sat on it. It is possible to sit on my sitbones in one spot, but it's really easy to slide off the sides. I can feel the edges of the saddle on my bones. When I don't actively watch my position, the saddle slides between my sitbones and I end up sitting on my soft tissue.
I also measured my sitbones with a piece of cardboard and then took a piece of clear plastic and marked the cardboard-imprints on it with an edding. Now I can take this "test-***" and put it on saddles to see where my sitbones would land. On the SI, my sitbbone-centers would land on the very edge, and I guess thats why I slip of so easily.

I didn't do a longer test ride however, because I think, as much as I like the looks of the saddle, it won't fit me anyways and it's quite expensive - so I'll send it back. I fear the muddy weather here wouldn't leave it in an "unused condition" if I took a ride.
