I usually have a cheap sram chain which I change every 1,000 miles or so for the longevity of the cassette.
However, I've obviously overdone it this time as I changed the chain and the new chain jumped and not just on the mid-range sprockets.
So I have put the old chain back on. The chainrings are hardly worn and I have a new rear mech on with, obviously, new jockey wheels.
The question is how long do I go with the old chain and cassette? I don't want to wear the chainrings or jockey wheels by carrying on using a "stretched" chain.

Thanks,

Steve

How long is a piece of string ....

Obviously you know that the only cure is a new cassette to go with your new chain, but I'm sure you can go with your old ones for now, but the sooner you bite the bullet and get a new cassette the better.

Make sure you keep your old drive-train as clean as you can, that way your chainrings will be happier.

It is not the jockey wheels that will suffer its the chain rings. If you wait long enough it'll be a whole new drive chain to replace. As above it's string measuring time.

Steve: are you sure your chain has actually stretched? I forked out £9.00 for a Park chain tool and spent a happy half hour checking most of our bikes - it's quite a fun tool to use and very simple (even for me). The results were not what I expected: yes, the usual suspect was, but others I had thought would be stretched weren't and vice versa.
