Test it
Take off one shoe and sock
Drop the ring onto your foot and if it sticks it then its too worn :wink:

FWIW....".... 8/9 speed where I assume that the ring is slightly thinner to accomodate the narrower chain and hence less metal so wears quicker ? "

The chain is narrower only in respect of the thinner side plates - the rollers and thus the ring on which they sit are the same. I think!
