I understand the physics of gravity and wind resistance so I don't need to find out about that, just that I have to put so much effort in getting my road bike up hills that aren't even steep. I'm an athletic person so it's not that I'm out of shape, is something wrong with my bicycle? What...
I'm touching up my old Schwinn road bike and I'm changing the flat handles to aero ones, which means I have to change the brake levers as well. Does changing the levers also mean I have to get new cables or will the old cables likely be compatible with the new levers too?
