I have a road bike that I commute to work on, just a 9km trip each way. I also have some tightness in my lower back, especially since I usually sit in front of a computer screen. My wife wants me to change my road bike set up so that I am no longer bent over when riding, but have a more upright posture. Can I change the stem and handle bars easily (and cheaply) for a flat bar configuration so as to turn my road bike into a commuter bike?
P.S. I am also planning on getting some panniers fitted, so as to take the weight of a backpack off me, but that will probably be another question.
