I would love to be able to work on the bikes myself, but I am generally at my house, awake for about 3 hours a night, and that includes eating and anything else I need to do. On the weekends I have to ride, I have two young kids, and I have various and sundry other household things that need to be done. I barely have the time to bring my bike to a shop, let alone work on it. That said, how long could it take to adjust two or three screws...
