I also got a new cassette. I put on the rear wheel and was fiddling with the barrel adjuster on the rear derailleur, and discovered that the dang thing was broken!!! Luckily, I had the Centaur rear derailleur I replaced with a Veloce medium cage on the Battaglin, so I swapped THAT in. Then the drivetrain sounded a little noisy, so despite the chain not being THAT old, I put a new chain on.

So, first observation is that, between 2006 and 2020, Fulcrum replaced the "Swarm Of Angry Bees" freewheel with something damn near SILENT!!! No more rolling up on slower riders and announcing my presence with the ridiculously loud buzzing of my freewheel! Mrs. GeneJockey suggested I get a bell....

I was planning a quick 16 miles but ended up going more like 26, because the smoke had blown out and I had the legs for it - or at least I had the legs to get to the turnaround point!
