Thanks for the folder suggestion. A better (and cheaper) option for me would be to just leave the house five minutes earlier so I can walk to the train (that's my normal modus operandi). I'd also prefer a more efficient bike when I commute (12 miles one way), which is typically all the time in nice weather. My actual nice bike (Madone 5.2) would never be left outside, and is essentially never ridden in the rain. The commuter was better than a beater, but not terrific. (Schwinn Madison, flat bars, Crank Brothers pedals.) The only thing kind of unique about it were the old Galli levers.
