WOW, did not know my inquiry would get such a reaction.* My bike is a touring road bike, not a tri bike nor a mountain bike.* Having backpacked many miles in the military (Semper Fi!) and having ridden many miles on a bike I now understand the balance issue with a backpack.* Since I plan to travel paved roads with my bike (Cannondaly 613) would I be better buying a rear rack and penniers or a trailer?
