This is a project I started to think about about 4 decades ago when I first came across the new "tensioned support" (or whatever was the tag line then) design of the Eclipse handle bar bags. The bar mount always seemed nice for access but poor for handling. Eclipse had an answer in their Seat Post Thing and my bags moved behind the seat ever since. But my frame size was a problem for easy access when riding and I sometimes rubbed the bag's corners with my legs. So I made my own SPT, adding length and height to the bag's placement. Next were the Madeden bags, may the company RIP, and my rack to hold them behind the seat off the post too. The last in this trip of different brand HB bags are the Arkels with their own bracket system that I also converted to a behind the seat location with a return to what is a version of a SPT.
All of these had their issues. Noise over bumps, ease of access, volume, weight, sway and bounce. The whole time I thought there was a better way and with my sort of retirement I have time to ride, contemplate and design in my head. Here's the recent end result as it is being made. This is version two with "improvements" and dimensional tweaks from the prototype. I'll add more history and photos as I get to them, riding is the first priority these days... Andy
