thanks!
used the RVtoys bag in italy and it was great for the trains. roomy and it very easily fit a folded dahon and fit nicely on the trenitalia luggage rack on the superfast train. the regional train that did not accept bikes was fine, too, but we had to stay with it in the passageway outside of the seating compartments...anyway.
good bag for the money, BUT the zipper broke on the last day.
also used the smaller (must remove front wheel) bag for the bike friday pocket rocket. much smaller bag and lighter. easier to carry in a pannier but not as convenient to quickly fold and hop on a train as the canvas rvtoys bag.
