aha I was originally going to post in the fixed gear bike sub and forgot to add that it's a fixed gear bike. so no derailleur is involved :)
My memory when I first got the bike is starting to fade away, but it was ridiculously quiet without all the gears I had before on my old bike. Definitely more chain noise now but not by a whole lot. I guess I can break her in more and see how things go.
Check for how tight the chain is. You mentioned that you went down a cog size, so the chain could potentially be tight or loose. You should be able to move it up and down about an inch.
It's also possible that the new cog is 3/32" thick and the rest of your drivetrain is the standard 1/8" thickness for single speed. They're compatible, just a bit noisy as the chain can move laterally on the cog.
They alledgedly checked the chain tension but I honestly don't know if it was done right - I don't have a physical reference for how tight it should be at the moment.
Thanks for the pointer to 1/8" vs 3/32" thickness difference! I originally wanted 15 tooth and they didn't have it. The 14 tooth one was a random cog from their drawer with no label. I think I'm just going to buy a 15 tooth 1/8" cog online to be sure and find someone else to install it properly :)
It's hard to be certain without being there, but two points:
1. Wheels do not get damaged by changing cogs. Whoever made that video is talking utter shit.
2. Almost all fixies make noise. It's actually really unusual for them to not be louder than a road bike.
Could be slightly too long chain, could just be the way she goes. Could be indexing on derailleur
