Daft idea IMHO. Front weight travels best as low as you can go. It’s obviously going to affect your centre of gravity being that high, and possibly force you into an oversteer. Why do something because it looks good? Don’t get it. Run big bags on a rear rack and get 25 litre bags for front on low riders. Surly (I’ve a pacer set up as a winter light tourer) focus in part on porteur type set ups, which are ok cruising round urban US, but not so good on the B2247 when you have to share it with Enid coming at you alongside in her old Fiesta...
