I saw your experiment when I was going through the older threads on the upgrade thread! Thanks for doing the “rack” work. Since we have the attachment points on the seatstays I want to concentrate on using those. To which, I have bought a new Bonty rack from my LBS to work a fit. It’s in conjunction with a trunk bag which also folds out two pannier sides. So far the tubular struts are hard to configure so they can reach the stay points/ drop out points and maintain a level deck. The description say it can fit on frames within my seat tube length.
I’ll have to mock some of the attempts up for you to see.
Thanks for reading and your input!
