remember the old-fangled handlebar bags that would mount with a solid rod
you had to pretzel around the stem and bars?
you could easily make something similar from a length of steel rod with thin plastic tubing to
protect your bars and stem. available at home depot, cost about $5. time required: 20 minutes.
consider this.
