I looooooove my Topeak explorer rack with the Topeak bag. The bag quick detaches from the rack in a second..literally. Take it with you everywhere. Nice bag too. Converts to panniers in addition to a regular trunk bag when the wife calls you to pick up groceries, but panniers bags tuck away to nothing when you don't need em. Tough bag too. Loooove it. Heck , I should be selling them.
