I have a question that so far has produced various answers.
Everyone knows that the ligther a bike......the easier it is to peddle up hill.
So, lets say I have 15 pounds of stuff that I need to bring into the forest with me. I can easily put attatch this 15 pounds of stuff to the bike frame OR I can carry it on my back.
The question is.....which method will be easier for hill climbing OR does it make no difference? (leave comfort of discomfort of backpack out of equation.)
My feeling is that it doens't matter. Once you get on the bike....you are essentially powering the load/weight together up the hill one way or the other.
