I am considering a small tank bag for things such as phone, passport, battery charger for when we go on tour.
I have read a few threads on here about some, but I am interested in what people have and the good and bad of them. I see that the tank ring bags are more expensive, but are the magnetic ones any good? Do they stay on ok or move easy, damage the paint easily?
As I say, it doesn't need to be very big as it won't have to hold too much at a time. Is there any "cheaper ones" that anybody has found to be ok?
