Chain slow when pack pedaling

[Ana]

So the chain needed replacing....I just didn't want to do it unless I was positive it would solve the problem. I removed the back wheel and spun the cassette and it seemed to be fine. I checked out the chain link-by-link and it seemed to have some stiff ones. I know a while back, it was near the brink of needing to be replaced (i.e. hitting the 12 1/4" mark).

So now my bike seems very happy with a new chain

Thanks for your suggestions I'm glad it was an easy fix (not a clean one, though )

I must say that there is something extremely satisfying about being able to work on your own bike

hitting the 12 1/4" mark

That's a typo, right? 12 links in 12-1/16" is the standard for when a chain is done.

Sheldon says 1/16" (or 1/8" is very much plenty). I will note it for next time I always have to look it up... I bet it needed to be replaced a while ago

Pedaling backwards is the classic way to look for stiff links. The jockey wheels will jump when a stiff link goes through them.

Once I got the new chain out, it was obvious that the old chain was done

I haven't ridden since the fall and now I'm beginning to remember that I knew the chain needed to be replaced but that I would do it later (i.e. during or after the winter)....

You should also check your cassette and chain ring teeth for wear. They usually wear together. Chains are usually steel and rings can be aluminum which will wear quicker. Have your LBS check everything
