Saddle for the Mature B-Boy

Sorry this is wrong.

Specialized saddles come in different widths; on their MTB team a few years back the guy who was build like a wippet and had no kind of arse or hips had the widest seat bones and therefore used the widest saddle.

For hybrid bikes and that sort of ride position I found their Sonoma saddle prove to be very popular.

I think when people say arse, they mean sit bones TBH.

I'm a chunky little fecker, but have medium spaced sit bones, and ride in quite an aggresive position. So I like a narrow saddle. I have a storika on the fixed, which looks like I'm trying to combine an interest in S&M with my riding. You'd never fit it to me by looks. I loves it though.

I think you need to consider the following:

Sit bone width (specialized have a scale for this)
Flexibility, or riding position (Fizik have a scale for this)
Weight (Selle San Marco have a scale for this)

...and even then it would still be trial and error.
