Bikepacking - a viable alternative to racks & panniers

I have the largest of the carradice saddlebags with the quick release and frame. It's ok but must weigh more than 2kg all up (empty). This weight up high is more of an issue when riding fixed as I tend to get out the saddle and move the bike around a bit.

I also notice that the SQR clamp is quite small, so the heavier the bag, the more prone it is to bump, I notice that with stonehedge's carradice as well when we were riding to Cumbria.

the beauty of Scott and other's design is that it spread the load all over the seatpost/saddle, giving it more support to keep the bag stabilised as well as closer to the seatpost, it also mean if it's half full of packed, it still be stable once strapped properly.

basically I'm echoing what scott said 2 years ago (and from my short ride yesterday).
