I currently have a Trek mtb and live in NYC. Am planning to quit the train (most of the time) for the summer and bike in out and of the city. I am looking to get a cyclocross bike that can deal with NYC roads. Was wondering if anyone can recommend a cyclo that is under $800. Preferably around $500-600. Also would drop bars seem better than mtb bars for city riding. My commute is going to be about 80-100 miles a week. Thanks in advance.
