I like the look of the Arkel, but I have a couple questions before I buy it, maybe you can answer. I like to errands on the way to work, so I want panniers that can store clothes and help with shopping, like a six pack of beer, a little fruit, drug store items, etc.

So does the Arkel have a place I can put my U-shaped citadel lock? It's about ten inches long. I don't want to dig into the main compartment every time I make a stop. Also, can I fit other things in there, is it good for picking up a few things at the store? Finally, is the idea that you just get one of these panniers? If so, maybe I buy one of these for clothes, computer, etc., and find another pannier that's more for errands and take them both with me? If so, any suggestions of a pannier for this purpose?
