Query: Nice Seat BIG PROBLEM

This is one of the better engineered bike seats made in China and it is comfortable EXCEPT FOR ONE BIG FLAW. I KNOW the Chinese did this on purpose, LOL. If you look close at the picture of the seat, you will see the cover is sewn in two pieces onto it to make it fit well. The lower edge (about two inches wide) that goes all the way around the bottom edge of this seat is ROUGH RUBBER! OUCH, you talk about rub burns!!!! I ride everyday about 20 miles at a time and when I got this seat, the first time I used it, I stop swearing under my breath about my butt hurting. This seat is comfortable and substantially reduces the pressure pain, BUT that rubber cover edge makes your shorts and underwear ride up like someone is giving you a weggie!!!... TOO BAD I like this otherwise.......its got to go back unless I can figure how to cover it with spandex.
