Yes, I looked at the Caddy and the Vario rack combo, which could allow me to just strap my bag on, but I was worried about interference with the cabling. Do you have any experience there? Do the cables get pushed behind, or does the rack need to go underneath them? How far down the handlepost can the clamp mount? If it's big enough to attach to the lower portion of the telescoping handlepost, that might be pretty attractive.

If there were some rear rack solution, though, I think that could be a simpler and more appealing place to carry weight.

Thanks for the suggestion!
