I just ordered a B67 Brooks. Love the idea of a 210 width. My Serfas is 180 width, which is just about the width of my sit bones. (outside edge to outside edge) So yes, each of my sitz is on the saddle, but only just barely. Not centered in the "middle" of each side of the saddle by a long shot! (a whole lot better than what my bike came with, however!) I ordered from www.wallbike.com and they give a 6 month trial period. I had a nice conversation with Bill, the owner. I was torn between 2 different saddles: B67 and B72. He told me to try one, and if I didn't love it to send it back and he'd send me the other.

gotta love a 6 month trial period!

My boss the bike goddess was appalled that I'd ordered a Brooks. But she has NO BUTT and little snake hips, so she has no idea what the wide-sitz folks have to deal with!
