Does anyone collect the old 1970s bike speedometers/bike computers? I have one of the first bike speedometers with the sweeping dials on it for cadence and speed. It really looks primitive by today's standards, but quite cool for a vintage restoration. I remember when I used to ride with John Howard who was on the Raliegh National team, and he often used this model. If anyone knows where I can find some pictures of them, or would like to see mine, I can send a picture.
