I'm nearly finished restoring a Follis 072. If you've done any digging, as I did, you probably discovered that there's not a whole lot of information available about Follis. I found a couple of references to frame tube materials that - quite frankly - are just a little bit suspect. I think that some bike owners are listing tube materials based more on hopefulness than actual knowledge; I discovered various bike database entries for Follis frames listing the tubing as Reynolds 531. Don't know about
their frames, but
mine is pretty heavy - substantially more so than my Peugeot PX-10 for instance, which I
know is constructed out of the mythical Reynolds material. I'd try lifting the frame by hand first to judge whether or not it's a lightweight racing material or not. Don't let that dissuade you though - Follis frames are handmade, and I'm very pleased with the way mine is taking shape.
