I haven't really decided. Normally I'd do drops, but the bosses on this bike aren't set up for down tube shifters. I don't want to change the spacing, or spend the money on brifters, so it looks like I have to use barcons. I know from experience that I don't really like barcons with drop bars, so I've been thinking about using either mustache bars or something like the Nitto albatross bars. I'm waiting for the right bars to speak to me.
