First off, I love bikes. I own a 2016 Salsa Fargo, a 1980 Motobecane Grand Jubile, and I'm building an 80's Kuwahara MTB frame up into a drop bar conversion. My tinkering revolves around 80's road bikes and MTBs. I've never been a fan of your standard, run of the mill, big box beach cruiser. I didn't know rat rods were a thing until maybe a year ago when I saw some photos of an old cruiser fit with cafe racer bars and a slammed-back seat post. That was love at first sight, but then I kinda just went about doing my own thing and totally forgot about it until the other day, when some guy rides past my house on a clearly custom-made bike. beautiful white powder coating, lines to die for, a gorgeous springer fork, and the coup de grace, a "down" tube running parallel to the ground, skimming only inches from the blacktop. I figured I need to get into this! Alas, funds are not forthcoming. There's someone in the neighborhood selling a Schwinn Swindler for $95, but I can probably talk him down to $75. The guy's a flipper, but a fairly conscientious one that doesn't part out much. I'm thinking about getting it, even though I've always tried to stay away from BBS bikes. I really like the frame, the wheels are true, but the spring is already developing rust on the inside of the coils. That's the one thing holding me back from buying it and pumping way too much money into it. Should I let this little bit of rust keep me from buying the bike?
