I'm currently looking for a new rack top bag (rack trunk) for my new road bike. Ideally, I would like to get one to match the bike, either silver, or grey, or silver/black. All black would be the last choice for color. At one time Cannondale made exactly the rack trunk I want, in silver and other colors including red, which I have one of, but their current product of this type is not nearly as good as their old ones. The closest thing I have found so far is Topeak's Super Trunk Bag. It needs to have at least 600 cubic inches of capacity, with expansion capability if possible, 2 side compartments, a carry handle and shoulder strap, and a rigid or very stiff liner to hold heavy items like a camera and binoculars in place. I know this is asking a lot, but it seems like the quality of many bicycle accessories has deteriorated since I last purchased any major items. If anyone has any idea where to get a rack top bag like this, I would appreciate any information. Thanks.
