Cole got this rear rack from Axiom and we threw it on his dad's Trek 7.3 before our 3 day tour, and it handled the job fine.
Weighing in at a mere 700 grams, this rear rack is super light, but super tough with it's triple stay design and sweep-back support for panniers. The stay length is adjustable, fitting 26", 27", and 700cc sizes. My dbl. sided panniers didn't show up in time, so i had to rock a single- no problems rack wise, although it did take a little getting used to of riding with an extra 50 or so pounds on one side. Topped off with a tent & sleeping bag, this rack held up great- no complaints. And when I left it, it still looked brand new.
One thing that surprised me- it comes with a lifetime guarantee! With that in hand, I don't see how you can go wrong.
