I've been checking out saddles recently. I think the LBS let me take about 4 or 5 home to try out in the end (not all at once). I measured 155 on their sit bone thingy & they say to get a 155mm saddle. Although looks to me like Specialized only make max width of 155mm.

I'm waiting for the Avatar Gel to arrive fingers crossed it will be the right saddle for me. If I need to go wider, I knw selle italia ldy is wider than that, and not sure about how many others.

I'm on a MTB though so don't want wider than necessary or real thick either.

If you have a good LBS they should let you try the saddles out & return if not suitable.
