I've recently put aerobars on my bike, and I don't want to take them off. Unfortunately, I can't use my handlebar bag with them on, and I miss having it. I also don't have much room between the bars and wheel (fender). So I've decided to try and make my own that will fit around my current setup.
I'm planning on making out of cordura, but I'm not sure totally sure what I'm going to make the bag's frame out of, or how I'm going to fasten it to my bike. Home depot sells some right angled aluminum bars (3/4"x3/4"), which seem strong enough and fairly light to do the trick for both the frame and fastening mechanism (along with some other miscellaneous hardware).
I'm just wondering if there might be a better solution. I have an arkel bag, and it uses some sort of plastic sheet bent along the bag's 4 sides, which seems to work well and would be less work to make. I just have no idea where I would go about finding such a product. Any ideas on what products I could use?
