Some years back, when living in the Cleveland area, I visited Joe Bringhelli one day. He helped me greatly back then, inviting me into his home and workshop, teaching me much.

Joe wasn't one to worry about frame weight, but he didn't hold it against me if I did. To a point, one day when asking about the weight of such and such a tube, he handed me a box of the tubes in question, along with a scale, and said do as you like. I sorted through a couple boxes, picking the lightest tubes I could find. One such tube was a Zero down tube, with 31.75 at the head tube and 35mm at the bottom bracket. The "baseball bat" tube. I also picked out a nice light 31.75 Zero top tube. Variation in these tubes was more than you might think. Between the two tubes, I saved about 50 grams. Ha ha. 50 grams = 2 ounces. I still have those tubes. They must be 25 years old now. Gotta get off my butt and get busy...
