Hello

From what you are describing it sounds like your indexing is off.

Thanks, but maybe I didn't describe the noise accurately enough. The noise happens regardless of what gear I am in... as I look down at the cassette while I'm spinning, it seems as though there is a 'wobble' in the cassette itself. That can't be good, but then I wondered if it wasn't the flexing of the bike and trainer caused by my body weight as I spin.

However...

Just now, when I was lubing the chain (again) to see if that was the issue, I could hear the chain 'click' once with each revolution of the cassette... as though it wasn't seating itself on the cassette properly in one spot. Ugh! This is driving me crazy! Back to the shop I go... third time is a charm... I wish they would get it dialed in!!

Is the cassette tight? Can you move it back and forth with your hands? Sounds like a loose cassette - perhaps you didn't place the appropriate spacer behind the cassette. Something to check.

Unlike many aluminium frames, carbon frames generally do not amplify mechanical noises.
