They are both in excellent shape. Must have hung in the garage most of the 40 years. I want to build new 700c wheels for them. With an internal geared five speed. A generator hub for the front.
Anyone know off hand what the rear spacing is for the hub?
Also, do they make a quick release seat post clamp for the old sized post?
Any other things I should know?
Thanks. I'm an old hand at bike maintenance but this is my first go around with a classic Schwinn.
So at 120mm, I was only able to find a three speed Sturmey that would fit it. I wanted to go with a five speed to get a little more gearing spread. Is there anything else out there that I'm not aware of?
You can get LED bulbs with the standard screw base, but they are a little problematic. They require DC current; but the dynamo puts out AC. They are brighter than the original bulbs, but the light source is not in the same place and this renders the original parabolic reflector pretty useless, negating the upgrade in power.
If you're willing to live with the latter problem, you can solve the former by putting in a bridge rectifier or, if you have both headlight and taillight run by the same dynamo, by reversing the polarity of one of the lights. That way, the single wire from the dynamo goes to the center contact of one bulb and the edge contact of the other; they'll light alternately and protect each other from reverse current.
