I just finished freshening up the 1973 Schwinn Speedster three speed that I picked up last week.
It was kind of crusty when I brought it home, but still wears its original paint and tires. The tires are pretty dry, but they still hold air. They have Schwinn Stingray Fastback molded right into the sidewall.
The seat was definitely replaced at some point. I'm not sure about the grips. That grip style was just starting to appear around that time and these are clearly very old. The whole color scheme was a bit of a puzzle to me. A white seat and grips would seem like the obvious original setup, but the brake levers were black and look like they always have been. So maybe the seat replaced an original black seat. It's hard to say after 40 years.
It's been really hot and humid here for a few weeks, so I brought it down to the basement, hung it from the ceiling and took it all apart.
I made a fork-like fixture to hold the wheels while I cleaned them up with a wire brush on the Dremel. One of those Thule wheel racks would have been perfect for the job, but I couldn't find a used one around here and I made this for about six bucks.
Various wire wheels were instrumental in this little project.
I removed the crank and cleaned up the bearing races.
The bearings were cleaned and repacked.
I took the brakes apart and polished everything.
There was something funky about the rear brake assembly. It was mounted behind the frame when I got the bike, but one side was twisted and I couldn't get the new pads to make good contact with the rim. I imagine that most of these bikes were assembled by a 16 year old in the back of a hardware store, so it may have been mounted wrong from the start. I decided to move the brake assembly to the front of the bracket. It looks better in back, but it works better in front. Safety first-ish...
It also cleaned up the cable routing a bit.
The Shimano 3 Speed Click Stick didn't need much attention.
I removed the shift rod and linkage from the rear hub an cleaned it up.
I added oil to the rear hub, probably for the first time in 40 years. When I was trying to figure out how to get oil into the tiny filler, I decided that something like a Hoppe's Gun Oil bottle would be best. I looked online to try to determine what type of oil to use and the only definitive info I could find was "Not Grease", so I just used Hoppe's Gun Oil, since it was already in the bottle.
I also decided that the black paint had to go.
I went to eBay and found a set of vintage white Schwinn grips with just the right amount of patina and a used white reproduction Schwinn seat. The seat looks too new, but it suits the bike much better than the old one.
I still need to true up the wheels and one of the pedals is kind of tweaked, but it rides smoother and quieter, looks a lot better and shifts about as well as any Shimano three speed did back in the 70's.
