Does anyone here use any "chamois butter" on long rides? I'm thinking about using some on the undercarriage for Squiggy, but I need to find some that doesn't have any fragrance (my skin reacts to soaps/lotions with fragrances...last thing I need is a rash in that area while I'm riding). Any suggestions on what I should use? I've heard some people use regular moisturizers (i.e. Noxema, Eucerin, etc). Does this stuff work as good as the chamois creams?
