SP is thankfully recovered from a serious illness, so to see her looking so good is fantastic, a very talented and respected all round presenter.
It has? Surely rolling away from the wheel to keep dirt out of the fold is the right way? And then the strap-over tightens the seal rather than loosens it? That's the way I've done the bag on my Scram
No, it's meant to be rolled thus, as per the user guide supplied (and there's no risk from the wheel such as you described)...
