Very good solution for suitcase or bag. That was also decisive for the purchase. Theft security at two uses by lockable zip closure. Star deduction because, although the maximum width of the rack is indicated, with me but the opposite was the case. The clearance between the carrier bars should be at least 100mm, otherwise the screws do not fit in between or the porter's highest 80mm wide then the screws are outside. I milled out the holes from the Klickfix carrier. Does not look nice, but you can see if the screws are hardly there. The spring clip from the porter had to be dismantled with me.
