I am having a somewhat serious issue. Whenever I ride any distance farther than about ten miles I experience chafing on the underside of the tip of the business. I have determined that this chafing is the result of the tip of the twig rubbing the border of the chamois, i.e. where the chamois stops and the lycra begins. I am 6'6", about 215lbs. I have a pair of Pearl Ultrasensor, and a pair of Nike Elite shorts. The Nike shorts are a bit better but in no way good. This totally sucks. Does anybody have any serious advice? I would really like to get some shorts that don't cause this problem. Thanks.
