I recently purchased off of Facebook V.B.P.A., this 1968 Sears Spyder 10 speed, 24" bike. (I love these frames) It's missing a bunch of parts but a good starting point. Last year I had a Shimano Automatic 5 Overdrive hub I could not get apart. Well I got it apart and respoked with some 12g's. It looks pretty good on that Jerald slick, too! I'm thinking of keeping it a 10 speed so it will be interesting to see how that works with the overdrive selector. We'll see how this build goes.
