I have my pannier, which I've posted about before. Nashbar makes the best cheap bags I've ever used. www.nashbar.com

I just joined the handlebar bag contingent: $2 at the LBS for a one-pocket with a map-flap tiny bar bag. Less than the price for a latte, how can you go wrong? I put it facing me so I can dig out goodies while I'm riding. (the way most folks use a Bento Box)
