I just measured my sit bones as closely as I could. I got 110 mm once and 120mm once. So I guess that I could be 105 to 125 mm. So now how do I measure my saddle to see if it is close to being the right width? I would think that the shape and softness of the saddle would matter like others have said but just what would be a ball park figure for the edge to edge distance on a saddle for sit bones of 125mm spacing?
