This might seem like a really basic question, but there's no harm in asking. I've never had a bicycle with drop handlebars. I've always had sort of standard horizontal bars with only one hand position, which is on the rubber grips. I'm outgrowing the bike I have now, and thinking of upgrading next year to something faster. Pretty much every faster bike has drop handlebars, but I'm not sure how to use them.
I understand that there are multiple hand positions. I'm sure I can figure out for myself which ones are more comfortable than others just by feel. But I don't want to necessarily do what feels natural, I want to ride properly. What are all the different hand positions available on drop bars? Which positions do you use in which scenarios?
I just don't want to put myself in a dangerous, uncomfortable, impractical, or stupid-looking situation by having my hands in the wrong place.
