I have an old touring bike that I am converting to a commuter. At the moment I use flat bars, and was thinking of trekking bars or similar. However, after giving it a quick spin (before the chain got stuck), I found the drop bars to be quite comfortable once I got used to them -- and the bike rode beautifully.
My question is, what are the advantages of using drop bars versus a more upright position beyond aerodynamics? Is my body better placed to use the pedals?
