Has anybody here personally repair his/her bike?

I do it all the time. I have an old copy of Bicycling Magazine's Bicycle Maintenance and Repair Book. To do it correctly requires all the proper tools and lots of patience to learn. I enjoy the act of repairing/restoring, but certainly understand why shops charge what the do.

Maintaining and repairing bicycles is one of my pleasures in life. Most things are pretty straight forward but you have to look at how things work. I'd be broke if I took all my issues to a shop. Great bike mechanics are sometimes hard to find for some reason.
