I agree with the p-clip suggestion, and that these wheels aren't really designed for loaded touring - though they may turn out fine, he isn't an especially heavy rider. I'd have thought the frame would be fine. I'd have thought the handling problems were most likely to relate to having too much weight exclusively on the back.

Reason: Replace "work" with "weight". Damn predictive text!
