I was trying on a pair a pair of short with a multidensity chamois and realized my sit bones don't line up anywhere close to the thickest part. When I sat on the saddle my sit bones were on the thinnest part of the chamois offering little padding. They seem to line up closer to narrow hourglass part of the chamois. Then I looked at my current Santini Twist Gel shorts and there in the same spot a wearing away groove in the gel. Is this normal or is this the result of a one size fits all chamois. I'm 5' 7" and then I realized this chamois would be the same chamois that they put in a size XXXL. Anyone with any thoughts on this.
