Ok, Knot. Question. My ischial tuberosities are about 140mm center to center. According to Walbike, and Sheldon Brown, the B17 I have is 170mm wide, though it kinda LOOKS like my sit-dimples are pretty close to where the metal support frame is... the b17 ought to fit, right? or is the B17 one of those saddles that is better for super-low handlebars that have you up front on your rami?
