Query: Roomy Bag

I bought this to use for running errands with my Trek 7000 hybrid. The bag is a snap to install on the rack. On my first trip, my heel touched the bag a couple of times. The problem was resolved by attaching the bag back further on the rack. There are two plastic inserts that are used to hold the bag open and make it more rigid. Some clear instructions on how to use these inserts would have been good. In use, the bag is capable of holding a bunch of groceries. I love how it folds flat against the bike when not in use.My only complaint (and it's a fairly minor one, at that) is that a second handle would make carrying it easier, when off of the bike.All in all, it's a great bag. I highly recommend it.
