its just a little project im doing for a short commuter to work. i have almost everything i need besides the head set and bottom bracket but i read you need a special adapter to put the BB in. I was wondering if anyone has done this conversion before or if anyone knows what size headset, BB and adapter i need for this bike? its a 70s Schwinn Chicago continental i attached a photo to this thread. any help would be greatly appreciated!!! im new to bike mechanics but i have worked on cars for over 10 years so im pretty good with a wrench.
