Touring Equipment

Like a complete tit I have managed to lose my pannier rack. I haven't seen it since I moved house so I imagine I lost it then. I'm a wally. I therefore need to buy one tomorrow - do I need to look for anything in particular? I can go to any central London bike shop and don't want to spend mega bucks, nor am I in any way worried about weight.

Unless you're carrying a huge amount of weight, any rack will be fine, just get those cheaper Tortec Ultralite one that you can get for about £20.
