I am still looking at panniers and wad reading some on crazyguyonbike web site about the Arkels vs Ortlieb. I like the Ortlieb roller plus but I am wondering about the mounting system vs the Arkel one. Waterproof bags are not a big priority to me.I am using Tubus front and rear racks. I am planning a cross country trip in a few years and will be doing some weekend,week long touring next year. Would like to get pros and cons people have had with the 2 panniers.
