Why use them? I know they have more hand positions than flat bars, but I rarely use the drops. When I do use the drops, I don't stay in that position for long. Mostly I use the tops and hoods. Bonuses are that I have cross top brake levers, the bar end shifters are nice, too, and the hoods are useful for hanging market bags off of.
How can drops be made better use of? Anyone out there just passionate about riding the drops? Anyone like another handlebar they like better? I think if I'd might like to try moustache handlebars to save myself some back strain.
I'm asking because I recently replaced the crappiest, most unsupportive Brooks leather handlebar tape with some Deda foam handlebar tape. I had to take my German Bike Mirror off. I haven't had a chance to put it back on and I've been experimenting with riding the drops, but I'm not sure how I'd rather use it, for one more hand position or to mount a bike mirror.
