I did some informal testing on my ride home today. My handlebar bag had about 12lbs of stuff total. At 7-9 mph I felt like the wheel flopped way too for me to leave my hands off the bars for too long. At 9-11it was much better. At 12 on up it straightened out pretty well and I wasn't worried at all. Could peel a banana at that point. Again, I only have 200 miles on the bike, and I'm sure there's experienced riders with a much stronger sense of balance than I currently have. But that's just my impressions as it stands right now. I need to test the same kind of riding with my Xcheck and see how that compares...
