"The Bicycle Built To Fly"

My 11 yo daughters bike. Everything has it's OG finish, nickel frame etc. With the exception of the chainring. I used the "canodizing" method on that (wanted to see how well it worked, and I dyed the tuffs to even the color difference out). This project started out with an 81 survivor, but the 81 had bad chrome. So I got the 78 frame, and put most of the parts on it. I changed out a few things that suited me better, and here it is. I'm very happy with the results, and was more than happy to build it for my daughter.
