15t freewheel Problem
So i finally found a 15t ACS freewheel to fix the gear ratio issues i was having with my conversion. I took my bike to my LBS to have them remove the old freewheel, install the new one, and adjust the chain length to fit the smaller freewheel.
Good news is, the smaller freewheel gives me the resistance i was hoping for! And it actually sounds way quiter (while coasting) than the new 16t freewheel i purchased with my new rear wheel. Bad news is, the chain/freewheel is making a loud noise when pedaling. sort of a grinding noise. at first i thought maybe the chain was just too loose (it doesnt look all that limp though) and that that was maybe causing some play, resulting in the noise. The noise ONLY happens when i am pedaling forward. it has also started to be punctuated by clicking.
After about 5 minutes of riding it, i went back to my LBS, and tried to describe to the mechanic the sound. He picked it up and spun the pedals (didnt put it on a lift) and said that it would probably take a bit of time for the chain to work with the new freewheel. I suggested a few things to check/change, but he didnt wanna adjust anything.
its been a couple days now, and the chain/freewheel is loud, noticeable.
Any ideas what could be the source of the noise? It's the same chain (minus a half-link) and just a new freewheel. So its gotta be one or the other or both. I'd hate to have to revert to the old 16t set up. Any ideas/suggestions?
