I have two issues going on with the bike, but this is the most visible one. I noticed this the other day by doing a simple once over on the bike. You can grab the rear sprocket and walk it a lot. If you look at the right side, the cush drives appear to be super loose in the carrier. I'm assuming this isn't normal? I've never noticed it before. All of the hardware is tight. Is this just a matter of replacing the cush drives? I'm concerned that the metal from the cush drives may have opened up the diameter of the hole it sits in.
