Pancho, do you use front panniers at all? I'm just wondering if that might influence the decision on how far back to have the propstand?
I've got the basic Decathlon stand on The Shiny Dawes and the hybrid, both with inner-tube protection (I haven't checked, but I hope it's protecting!). No problems with either but they do need a 2.5mm allen key to adjust the length of the leg, which was slightly annoying.
