I have never done a survey (till now) on this subject, but I have often thought about it. Why? Because I don’t use chamois cream and never have. I do know one or two riders who slather the stuff on even for a 50km ride, but I didn’t even have it ‘down there’ for my 18.5 hrs at the Tour de Mont Blanc (although I will admit it felt like a fiery inferno under the bibs in the last few hours).
So…gimmick or actually something useful? My guess is that this stuff is necessary for pro cyclists (or the few maniacs I know who ride nearly as much as them), simply because they are on that saddle so much. For the rest of us, it’s probably something we do to make us feel like a cyclist, like shaving our legs or being proud when we’re skinny. Or maybe we just like the “ice-blue freshness” that you get after application.
So who uses this stuff? You?
