Hello all, I need to replace the big chainring on my venerable 2010 Allez Comp , and I was wondering if it's a case of just getting the latest, up to date 105 ring and chain?

Like these:

Do I need to think about replacing the cassette/jockey wheels/small ring?

Thanks for any help.

Usually you need to replace the cassette and chain.

Chainring tend not to be necessary unless it's obviously worn out.

Cheers Ed, much appreciated.

Is there a telltale indicator that I need to change my cassette, or should I just have expected a bit of cable stretch and rewire with a new chain?
