I know this post is older, but I'll chime in....

OK, my bike is un-rideable atm due to another lbs mechanic mishap, grrr. However, I do have both these saddle on my dr table. I took each for just a quick neighborhood spin as I realized my bike my not right from the shop, and had to stop til I go back in. Will post more later as I think both these saddles have potential from all I have tried. Actually, these two are the last of all the SI line that are 140 plus, I've seen them all...

The Signo at frst I thought would be an immediate return. It's rock hard, looks pretty narrow for 143, and slants downward at the platform, vs flat. BUT.... I actually was shocked at how it fit my sitz bones. I mean shocked as in a good way. As I noticed my bike was going weird, I switched up to the ProLink. It's pretty good too compared to the others.

The ProLink is more padded than the Signo. It's like a lady SI SLR, but the nose seems skinner. The cut out is different. Less hole space, and more filled in saddle surface.

Great narrow noses on both these saddles as they are mens. No inner thigh chaffing, or instant rub where the top of the hams meet the glutes.

But... wider than the SI SLR mens, which is about 130 if I recall. That I know for sure is too narrow for me. I'm about 140 sitz bones.

I really have been thinking all along I needed wider. Now, I'm thinking the winner saddle for this "lady" in the end might indeed be a "mens".

Go figure...
