A wide variety of racks, panniers, fenders, lights, bags, bells, etc. I don't know if it's true everywhere, but I find it very hard to find commuting stuff in Houston. I hate that I have to go to 4 or 5 shops trying to find a product and then end up buying it on line after I spent $10 in gas. Or, I have to get 1 thing at 3 shops to fill my 3 part shopping list. I end up buying things on line even though I want to spend my money locally.
