1987 GT Mach One

This 1987 GT Mach One is my first built since joining the museum. Everything on this bike, aside from the chain, was bought from museum members... I'd like to thank all the great sellers for setting me up and the guys who bought stuff from me too cause that helped fund this build. Putting this together was so enjoyable for me. The hardest part was the bottom bracket (my first ever sealed BB)... Actually that was the second hardest part, the hardest part was waiting for parts to show up in the mail. I think I called my wife from work everyday asking if anything showed up for me each day lol. I have rider wheels for it too and have already had it out a couple times... it rides like a brand new bike just as it should. Hope you like it :)
