The Topeak has a plastic attachment that sometimes can vibrate the
cross-seatbar attachment off. But because of the size of the bag it
cannot rotate the bag into any position in which it could shake off.
I use them on everything now.

There is another method that has a locking bar that is almost
impossible to release even when you know how. Those work well too.

I found this kind of plastic latch to eventually break off on the MTB if
their are used in a "rigid" way, meaning without a strap in line with it.
