Had lunch with a few old friends in our periodic Geezers 2.0 luncheon, then rode 26 miles on the Montour Trail. Nothing unusual other than truly great weather.

I've put a few hundred miles on the bike since a new drivetrain was installed, including new cables and housings, and there's been a bit of gear chatter and uncommanded shifts on the rear cassette which I attribute to the new cables stretching after use. I am not a derailleur guru, but I was bold enough to make a one-half turn on the cable adjustment, and then another half-turn later on.
When I got off the bike and back to the web, I read Sheldon Brown (RIP) on the topic and then found this video and it was pretty straightforward, just FYI:
What eludes me about cable stretch are the implications for civil engineering. When they build a suspension bridge, there aren't any adjusters for cable stretch built into the mechanism. If cables stretch after break-in, shouldn't the bridges sag? Conversely, if the bridges aren't sagging then the cables aren't stretching, and then what is this craziness the bicyclists are putting up with?
