Chamois Butt'r is for people who don't like getting a sore butt from riding bikes. (Everybody right) Actually not everybody needs Chamois Butt'r. It's really for people that are doing longer rides (I know, define "longer" right?) The longer you ride the more friction your butt experiences. Too much friction is no fun and can be quite painful after awhile. Chamois Butt'r acts as a lubricant greatly reducing the amount of friction allowing you ride longer more comfortably.
