I bought a Core about six weeks ago. Zero issues to start. Then I noticed my Garmin power numbers started creeping up vs the Core (+15 to 20W where they had been less than 10). I initially wrote it off to drivetrain loss (which actually turned out to be correct). I realized that as the power gap started growing I started having some squeaking. I thought it was from the Core. It has steadily worsened the past few weeks.
This morning about 20 minutes into my workout the light bulb went off. Grabbed some lube and hit the cassette / chain. Within 5 minutes all squeaking had ceased and power numbers were back in line.
So this is my knucklehead PSA to anyone grabbing a new direct drive. Lube it up. Especially if you're dropping a brand new cassette on. I've ridden wheel-on trainers for years and don't recall ever adding lube while indoors.
