A chain wear checker

[Wester]

Which one would you recommend that is not expensive and does that job that it should do

 

[Tim Hall]

Twelve inch steel ruler.

 

[LCpl Boiled Egg]

Yep, as above.

^^^ This, and it can be used for measuring other things too.

On a new chain 24 links measure 12" measured to the pin centres. If you replace when worn to 12" and 1/16th you may get away with reusing the cassette.

 

[Wester]

I read somewhere that if you replace your chain when it should be replaced that you can get through 4 chains before your cassette has got to be replaced

True or false

True or false

Too many variables to say for definite, such as the quality of the cassette and the conditions you ride in, but if the chains are replaced in good time you should usually get through two chains per cassette and probably more.

I've got an Ice Toolz chain checker and it works a treat. Cost around a tenner I think.

These tools do not check for chain wear correctly as they measure inside the rollers

 

[YahudaMoon]

This Shimano one measures correctly as it measures outside the rollers

Its about £80

Or as pointed out above, just use a ruler

 

[DRM]

I've got one of these, bit ott but very accurate

I wouldn't spend more than a tenner on a chain wear checker myself. £80 is a bit excessive to check a throw away £20 item.
I appreciate a knackered chain will knacker a cassette and chain rings eventually but ask yourself if you'd spend £80 to check the tread depth of your car tyres. I'm sure not many would and that has to be more important?

Twelve inch steel ruler.

Or if regicide doesn't appeal then a 12" engineering rule might be better.

I thought of you when I typed that.
