You know something rigid enough to connect the two sides in daily use but deliberately weak enough to shear under the right circumstances?
Tom and I had some deep conversations on this topic in the design phase. I was initially pretty firm on connecting them. I've come around to Tom's way of thinking now. For one, I think that many rack problems have to do with the nature of baggage people run on them. I once lusted for big, hard cases. I have them on other bikes. I will never run them off-road again. Soft bags are much more forgiving than hard cases in a fall. I've never come even close to losing one on the rough stuff. I cannot say that for hard cases. I just did a 3500 mile mixed-surface tour on my KLR with Wolfman expedition bags. I had zero problems. At times, I wished for greater capacity, but I'm glad I had to pack somewhat frugally. Extra weight was not my friend in the tough stuff.

I think that hard cases also tend to transfer harmonics to racks in a much different way. The soft bags really can't develop much of a resonant frequency, while most hard cases do at some point. It's the resonance as much as anything that leads to cracking.

That being said, it would be a relatively simple thing to add a rear loop. If Tom decides to offer one, I suggest it be an optional extra, which could be unbolted if not needed.
