I've not had a problem with my bagaboo (a teeny tiny one admittedly) on longer rides of up to 150 miles. Mind you, I don't carry laptop or shoes in it, just food, drink, rainwear and other spare garb, a few tools and lights/batteries.
Much nicer than a rucksack in my opinion, as it allows more movement and more air to get to your back.
