In a small way similar to a Corbin Gunfighter . I had (Seat Guy) Name of Business modify my seat. Some may not like to look but it delivers the goods for me so far. When I taken a LONG trip I start to get leg cramping after the third or fourth tank. This is more of a problem for me then the dreaded num bum . At any rate If you like riding your bike a long distance and you have discomfort , look into this. I raised my seat height about an inch and that relaxed the bend in my knees and what a difference that made.
