70's Bridgestone

Could somebody tell me about this model. Is it really alloy (alum)? I can't find a 70's catalogue. Is this a mid-range model?

Using "alloy" to indicate aluminum is a misnomer. Any metal comprising one or more chemical elements is an alloy. All steels are alloys because it is comprised of iron and carbon, with various other elements added in small amounts to give the resultant material the desired properties. Very few pure metals are used in products.

In this the case, the frame uses Bridgestone's Technart process whereby the lugs are die cast around the tubes. This allowed the fabrication of frames from of hard to join and dissimilar materials. Bridgestone produced these frame in steel, stainless steel, aluminum and combinations of these materials. The frame is probably an a Superlight with aluminum tubing. If so, the rear dropouts will have sockets that the stays plug into. Alternately, you can test the material with a magnet.

Yes, that is definitely a Superlight based on the dropouts. Despite the name it really wasn't that light. This one appears to be early 1970s boom era but the serial number will allow us to determine the exact year. During the peak of the boom, the Superlight was 7th in a line of 10 adult 10 speeds. Personally, I consider it an upper, entry level model, though some may consider it lower, mid-range.
