Corroplast, string trimmer line, and double-face tape may seem like unlikely elements for increasing your existing framebag capacity. One of the keys to comfortably riding with the widest possible frame bag is to be able to control the width through the sweep areas of the cranks, pedals, and feet. This simple retrofit will allow you to control the width in the lower frame bag area while filling the rest of the bag to maximum capacity. The fabric panel in front of the seat tube is also an area that benefits from width-control as it helps prevent the sides from bulging. The corroplast can be up-cycled from discarded lawn signs.
