>>1178309this is for a reasonably light trunk bag. imo that is redundant when you can get large seatpost bags like pic related which are more stable, lighter, easier to remove, have better weight distribution and are far less likely to break, especially on rough roads. In the wind, the leaf bends the twig breaks.
I also think carradice bagman style supports are cooler if you just want a light load there and don't want a full size rack/ don't have rack mounts;
