Chain wear or worn out?

tonysj

Hi all.
I've been trying to check if my chain fitted to my Boardman team carbon is just wearing or worn out and needs reolacing .
Its a 10sp tiagra and ive done around 1500 miles since december 2016. Now some of that has been during winter when the roads are s**ted up with grime and road salt.
I've checked online and there seems to be a number of camps who recommend when a chain is worn out and needs replacing.
I don't have any tools that check chain wear so can only go by what I've read online.
My chain measures 12 inches and 3 - 32nds over what when new is 12 inched over 12 chain links.
Is this worn or worn out?
Regards.
Tony

Get a good chain wear indicator tool like the Park Tool CC2 and judge it by that.
It does amaze me that people will splurge x 000 on a bike and then go chivvy about spending a few quid on a new chain to replace one they haven't bothered to keep up maintained .

Im amazed to find out the vast difference in chain mileage having read up.I realise by leaving the chsin oiled but covered in s**t was probably not the best way to go about getting a low wear from the chain.
I "think" that riding my bike over winter and not cleaning it religiously may have been an underlying factor. Just wanting other people's tjoughts as i never measuted the chsin when it was new.

at 3/32 i'd change it, by 1/8 it's likely to mess up the cassette so that it skips on some cogs - if things get that far you may as well run the old chain and cassette until they are really trashed, then change both

Sling this on your next Wiggle order, worth it for the price of a coffee/pint.

As above. Buy a wear indicator. Mine has around 1,200 mostly dry miles on it and is not far off needing changing. Leave it too long and things get costly
