bikes

Instead of a tube which has a consistent thickness, butted tubes are cut in a way where the center is very thin and the edges are thicker. A good steel frame is actually a bit lighter and much more durable than aluminum.

yardsale bikes are often really good deals, heavy fucking steel frame bikes from the 50s-80s that last forever and have bearings that can be repacked by hand. they weigh a ton, but last forever.

Its really hit or miss. Road bikes started to get really big in the 70s and a lot of manufacturers started making cheap shit to fill a gap. The trick is to look for butted steel tubing: http://www.reynoldstechnology.biz/materials/how-butted-tubing-is-made/.

What's the difference between butted tubing and non-butted tubing? Why do you need to look for it?

I always wondered how they made those weirdly shaped tubes of varying thickness. Now I know!
