Hi. Trying to figure out how to attach a rear rack to my bike. I have eyelets down near the rear sprocket that I can attach the bottom brackets to but I have no holes (I think they are called brazeons) or fittings to attached the top of the rack to the bike. I have looked at the racks that attached to the seat post but they look like they would sway and move around. I want to start commuting and need to carry a change of clothes and a laptop computer and a planner. Probably 15-18 pounds or so.
Any thoughts or fixes? Is a backpack just as good?
