I currently ride a specialized power pro at 168mm wide. When I had my sit bones measured last year when buying the bike they measured at 160mm. I've got a fairly large frame, 6'6 wide shoulders but I don't weigh a lot which may also contribute to the saddle fit issue. At 190ish pounds I sit on my sit bones.

Last year they told me the widest they had was 168mm, so thats what we went with but they also told me that ideally you buy 15 to 20mm over what you measure. This would allow for proper placement of sit bones on the "cheeks" of the saddle. There's not much available.

The issue I'm having is some prostate irritation on longer rides, too much pressure right in the center and toward the back. Helps some when I'm on the drops but at the end of the day many of these saddles while wide, taper quickly beyond the center. It seems I need something that's wider and flat(ish) instead of falling off quickly down to the edges.

Reading a bunch of reviews from various cycle sites I found these two options:
https://www.amazon.com/Selle-Royal-R...icycle+saddles

https://www.amazon.com/Planet-Bike-R...icycle+saddles

These are both side and don't have a ton of taper they're also cheap so I think I might give one a try. But I wanted to check with you guys first to see if you had any suggestions or thoughts on saddles and things that could help my situation.
