Need help here
What to do...
I recently purchased a new rear rim and cog for my bike specifically for use on my trainer. I was getting really tired of changing over my tires so I decided to have a wheelset for my indoor trainer and a wheelset for outdoor use. The problem is this. When I change over to my trainer wheelset my chain makes a grinding noise because it has been broken into my outdoor cog wheelset and now the new cog doesn't seem to run as smoothly with the chain.
My concern is that I am damaging something. Is it ok to continue riding the trainer until my new cog is broken in, or is there something else I should be considering here...
Thanks for the help

check to be sure line up is good. If so, probably need to install a new chain. It is easy to measure a chain and know if it needs replacement but I forgot the specifics. I think you measure 12 links and should be 12 inches. if more than 1/8 more, needs to be replaced. Others will post if this is wrong. using a worn chain will damage both your new and outdoor casset.

More than likely the spacing is slightly different. So your rear der is not lined up perfectly on the training wheel. You may need to shim the cassette a hair.

Could be a worn chain (in which case you should replace it!), or the new hub might pposition the cassette slighty differently, so the chain is not quite centered on the gear.

I have 3500 kms on this chain and outdoor cog. I didn't think that was enough to justify a change.

A chain usually lasts me somewhere around 3000 miles. At 2000 I start checking it whenever I clean the bike.
