sorry I am no help, I use a specialized cut out and love it! I don't use aerobars right now - I hope I don't have that problem when I get them. This is the first saddle that HASN'T hurt me! Could it be your shorts? I have had problems with mine, they tend to bunch up and cause rubbing. I have one pair that doesn't and they happen to be bright turquoise![]()
I hope you have some luck soon, someone here may be able to help you.
