Just received a new Ortlieb Ultimate 4 medium handlebar bag (new one that locks to the handlebar). Oh the problems of buying sight-unseen. Ortlieb uses a cable that wraps around the handlebar and stem to affix the bag. It is a mounting system that makes sense, but NOT for a Bike Friday where the hanclebars are split in half for packing. Has anybody out there solved this problem. If nobody has a solution, I guess it will go on E-Bay. After going through the Arkel-Ortlieb-Arkel-Ortlieb debate, it looks like I made the wrong choice. Any ideas?
