Hi, I need to survive 2 nights with what I can carry on my bike. Will be staying in hotels so no tent, towels etc. needed. I don't want to fit a full rack (no upper mounts and no desire for P-clips) but also don't want to use a back pack. Has anyone got experience of the "beam" racks that clamp onto the seatpost? Are they secure or can they bounce around.
What bags are good to sit on these? I'm thinking medium would be suitable to carry a light pair of trousers, trainers, top and wash kit.
