Odd Chainring Question
PLEASE forgive me if some kind of search might help me here, none of the terms I tried turned up anything.
Basically my chain will go slack and then tight with each revolution of the chainring, not so much that I notice when riding other than the sound changing, but still enough that it can go from almost totally tight to about 1/2 inch of slack (based on my perception, not actual measurement). I tried loosening all the chainring bolts and shifting the chainring around, but that didn't help.
I guess I'm trying to see if anyone else has experienced this and/or might have some sort of advice about it. Thanks!
