I have a Giant OCR C2 carbon frame bike that I'd like to use for short, 2 or 3 day trips and was wondering what my options are, as far as mounting a rack/panniers or other types of luggage. I think about 1 to 1.5 cubic feet of storage would be more than enough. There are no eyelets on the frame and I'm leery of seatpost-mounted racks (they'd put a lot of stress on the seatpost). I'd prefer not to use a backpack, for comfort reasons.
Perhaps a handlebar bag? Does anyone know of one that's fairly aerodynamic and won't create a lot of drag? I'd appreciate any other suggestions as well.
