This Peugeot was bought in 1975 by my father for $350, originally had down tube shifters that my father modified into bar-ends.
When I dug this out of storage last week it was in pretty rough shape, the original wheels were very non-true, the brake hoods were dried out and flaking apart, and the bar tape had taken a beating, and the Brooks saddle was so dried out (having never seen a leather saddle before) that I thought the bike had a wooden seat.
I began by rubbing nearly a full can of proofide underneath the saddle over the course of the week to start rehydrating it. I replaced the wheels (originally sew ups) with some 27" alloy quick release clinchers I was able to find on Craigslist. Ran new brake cables and installed new black brake hoods (I looked for tan like the originals, but was unable to find any) and wrapped new tape on the bars (The original was black, but I like the white quite a bit.) Lastly put some tan wall tires on it to keep the vintage feel and installed a modern bike computer to show that even though the bike is approaching 40 years old, it still has plenty of life in it today.
