Follow on question - if I decide to buy a new chain, how likely is it that the rear sprockets / front chain rings are worn with the old chain and they will not run smoothly with a replacement chain ...?
(Edit - chain is the original when I bought the bike & that's more than 12 years ago, I currently do between 1000 & 2000 km a year, although a few years ago that figure would have been lower.)
