I put a new larger cassette and longer chain on my new road disc bike. It shifted fine but was a little noisy on the stand. When I rode it the drivetrain was really a lot noisier than normal but it shifted fine in all gears. I did notice the crank didn’t spin as easily going backwards. I did several rides with it and the longest was 80 miles. I’m thinking I just got a noisy chain.
I finally put it back on the stand and immediately spot the issue. I had threaded the chain over (instead of under) the short metal bar between the plates on RD between the jockey and guide pulleys. Felt like an idiot!!
At least I haven’t succumbed to duct tape......yet!
Hard to see but the chain should have come off the bottom of the upper wheel in the photo. It’s also all cleaned up now as well......
Made that mistake just last week! Similarly, I went for a ride after changing the chain and it was noisier than usual ... mis-diagnosed at first and was playing around with the front derailleur adjustment. Finally, set up my other bike side-by-side to the faulty bike and notices the chain was threaded over that little tab. Fortunately, I installed a KMC chain so, with the quick link, it was easier to fix.
