The timing of and theme of this build couldn't be better. I've been acquiring parts to build a bike for my son Ben's 8th birthday that's coming up in April. This will make an already enjoyable project even better. The frame is a '55 schwinn #s27683 and the color will be blue. I was thinking about lacing an s-2 to a front hub and running them front and rear with 2-1/4" tires. I'm waiting on the rims to be delivered, I won 2 unlaced s-2's and an s-7 as a package deal on epay, so if the s-2 with tire won't fit up front I still have the s-7. Does anyone know if this will fit? I haven't touched a 20" schwinn canileaver since I was 13, (1978) henceforth my ignorance. The sprocket cleaned up nice as did the fork cap but the crank is bent. Won a NOS crank on epay last night. I'm also waiting on delivery of a bendix redline and I'm watching a NICE seat. I just need pedals, tires, a front hub and spokes.This bike is costing more than almost all my other bikes (bicycles, that is) put together! The things we do for love.
