I own a Trek District. I swapped out the original riser bars for some Nitto drop bars. Admittedly, I like the look of the drops better than the risers. The drop bars "feel" faster when I'm riding in the drops but I don't know if that's because they feel sporty or if I am actually faster with them. Most of my riding is around town. Anybody know how much of a speed advantage drops offer? I know I miss the added leverage of the risers for climbing hills. What are your thoughts? Anybody have any hard data?
