I have a 1989 Schwinn Tempo that I'm taking on as my first restoration project. Hang with me here, I'm new to this and trying to learn as much as I can about the materials, parts, processes, etc. I have noticed at the bottom of the down tube is a decal that says "Columbus, Tubi Speciali Rinforzati, Acciaio CrMo Cyclex, Tenax SL, Tre Tubi." Can anybody help me understand what I'm working with, please? Is this a steel frame? Or something else? When I search online, I find a lot of similar decals, but no exact matches, is it unique? I have stripped the bike down to the frame and am now considering taking it to a shop to get professionally blasted and painted/coated. I just want to make sure I'm not doing anything wrong. Any help/advice is appreciated! This is my first rebuild/refurbish! I'm pretty stoked, but want to do it right! This was my first road bike years ago and I would love to restore it and make it last! Thanks!
