What are the pros and cons of drop bars vs trekking/butterfly bars for a touring bike? I am rebuilding a Trek 520 and realizing this is a kind of crucial decision point since it will determine the shifters etc. I would porbably go with bar end shifters if I get drop bars but I am not sure about trekking ones. It's a lot easier for me to find drop bars but I have only had one other bike with drop bars and didn't find them all that comfortable. Does anyone have any advice on how to make this decision?
