Two different ways to pack a bike. They both work. My wife likes most the weight (35 lbs.max) on the back, and has no problems. She pulled away from me when I was going 40 mph on a downhill, and has never had an issue. I carry a little more weight, and like the load more balanced between the front and the rear.
She also has no difficulty pushing her bike through awkward places, like going around these road barriers.
I believe this was in one of Jim Blackburn's catalogs.
This is what I used for one of my bikes that did not have a fork blade attachment point. They are made by Tubus and work well.
Make a packing list. This one was for a 2 month trip, but was changed before leaving for the ride.
