I did a short, week long tour this summer with my new Ortliebs front and rear. I liked them for their simplicity and capacity. I was quite surprised and disappointed to see the wear in the legs of the OMM Ultimate rack where the lower retainer hook track made contact. Just a week of smooth hwy riding. I hate to think what a longer tour would do. Anyone else had this happen? Any good sloutions? I am thinking maybe a steel hose clamp at the contact points. Tape or rubber hose wraps would wear out faster than the aluminum.
