My mid-80s (and purchased new!) Peugeot Canyon Express is a war horse. After my "ridin' bike" was stolen, I got it out of the lean-to shed, dusted it off (and pulled a few weeds and cobwebs off), aired up the tires, put WD-40 on the rusty chain, and rode.
Today I'll hit 200 miles, since that day. I've oiled the chain (with real oil, rather than WD-40). I patched a tire - goathead! (It had been so long since I last disassembled the tire that it and the tube seemed "chemically fused" - I had to gently peel them apart.) I've had to tighten the seat bolt a couple times. The post is much newer than the rest of the bike and has some sort of "shock absorber" built in, but that bolt (just under the saddle) has unexplainedly loosened. (Next time - Loc-tite.) Other than that... no problemo.
It's a little harder to roll those 2.1-inch tires than the 1.1-inchers I'm used to. My wrists are telling me they're not accustomed to the hand position, although it doesn't feel uncomfortable. The nostalgic "friction shifting" (remember?) isn't as precise or fast as the click-shifters. But I don't shift a whole lot.
I really miss the trailer! I can't pull it without the special Bob skewer, and the Peugeot has a solid axle with bolts, rather than the quick-release. Mackie is both patient and sympathetic. She tells me, "I'll get you a new bike, ba-dah." (She can say "grandpa" now - in fact she talks nonstop and can say 'most everything... but still calls me "ba-dah.")
Regarding the new bike - I've paid my $500 deductible. I'm supposed to get a replacement Cannondale touring bike with all accessories pre-installed, shipped to my front door. I'm antsy. (Hoping I'm not tempted to "break it in" when the roads are mucky.)
