Has anybody else felt that the B17 was too narrow in the seat and/or the outsides the saddle rubbed/pushed into their butt? I like the firmness of the saddle, but I can "feel" the outline of the saddle towards the back pressing into my butt when I ride. I'm wondering if maybe I should've gone for the B68. My sitbones feel supported...it's just the outline "issue". The retailer told me to tighten the saddle underneath and that should "pull the leather under a bit". Anyone else have experience with this??
