Weight distribution: Saddlebag vs Handlebar bag
I've been commuting to work for the last year with a backpack weighing about 7 lbs. I recently bought a Carradice saddlebag to take the load off my back. I don't know if it's psychological or what, but I feel "weighed down" by the change in weight distribution. The saddlebag actually doesn't weigh anymore than my backpack, but the bike all of a sudden feels a bit sluggish and I'm required to use a lower gear.
My question is, if I were to get a handlebar bag instead, would the weight (being more evenly distributed across the bike) make it easier to pedal? Or, again, is it simply psychological? How does having a handlebar bag affect steering? I weigh 137 lbs and ride a steel bike, if any of that matters.
