Which im sure you could easily make out of something designed to clamp onto the post.
Does anyone make a decent seat pack stabiliser? Similar to the Porcelain Rocket pack, but not specific to that bag. I find I need to cinch my bag down pretty regularly to stop sway out of the saddle.
Also descending rocky trails, or anything with a drop bigger than a curb, is a bit sketchy as I can't get weight as far back as I'd like. Any solution? I suppose a dropper isn't going to work with a seat pack?
