I'm Andy and I'm a commuting junkie. Did I come to the right place for help? I'm an aircraft mechanic and I must say, planes are easier to work on than a bike most times. My ride to work is about 21km one way, 13 miles for you metric challenged. It's a '03 Devinci Amsterdam with a few upgrades. Who hasn't upgraded their ride? One day I may invest in a rear rack/pannier. The backpack works for now. The only thing I am swapping out is the eggbeaters and going back to shimano's. After 2 months, I still find them a pain to get in and out of, especially in heavy traffic.
