Hello,
I went with an axiom streamliner disc dlx for a rack for a very specific reason that may help you.
The bike I mounted it to is a GT Grade aluminum frame. It had only one set of eyelets for either a rack or mudguards but not both. If you look at the way the rack comes, there are these clips that you can slide a quick release through and then the stays bolt up to the rack eyelets on my seat post collar.
I removed the clips from the rack, used the forward set of holes on the rack to attach it to my bike and the rear set of holes on the rack to attach my mudguards to it. The only reason I did that is because with the clips, the weight bias on my bike was too far back and this frame didn't seem to ride well. Removing the clips brought the weight closer to me (still no heelstrike) and allowed me to still keep my mudguards mounted without having to use p clamps to attach the mudguards to my frame.
Seems convoluted but its much simpler in pictures that I don't have. In any case, it's a very sturdy rack and I've not had any problems with it at all.
I use ortlieb panniers that I bought on sale at REI, otherwise, I was going to get the topeak setup.
