I'm actually not new to cycling, but the vast majority of my riding for the last 7 years has been on recumbents. I recently got an upright Serotta, and have experienced some discomfort in that area that we usually don't talk about on other boards. I had a sample of Chamois Butt'r that I got as a freebie on a ride, so I tried using it yesterday, and it was a big improvement. Is this what other people use? Any recommendations?
