I knew the chain on the Orange was long past its sell-by, tried it on the Salsa - not too much of a surprise that that's dead too, then the Airnimal - just fitted that chain two (2) months ago - according to the chain checker it's dead too. What's going on? 2 months? Ok, it's my commuting bike and it is winter but even so, 2 months?....

What sort of miles do you do on it?

16 each way 3 or 4 x per week

strangely i got a chain checker and its never once indicated any wear in a chain, how accurate are they?

Hmm, well that's not a massive amount of miles, but depends on how you ride, I suppose. My suggestion would be to nip in to a shop and ask one of the spannermonkeys in there to have a look and give you a second opinion. Most use either the Park or Rohloff checkers, which seem to be accurate enough!

if the cassete and chain rings are worn they will accelerate the wear rate on a new chain. That or tools just a bit out of whack.

No, it's a puny amount of miles. My thoughts are: BBB £5.99 Park c.£16 - how accurate is the BBB? I shall take your advice and get a second opinion. Thanks

All put on new at the same time.

Use a ruler. No, not a joke. Hold the ruler against the links, one full link (ie 2 pins) should measure 1" so along the whole 12" of the ruler, the 24 pins should line up. 12 and 1/8th" means chain = dead.
That's how I've always measured chains, IME chain checkers always over-record chain wear. If I was being cynical I'd say they're trying to increase sales of new chains...Posted 1 year ago # -
crazy legs, will give that a try. thanks. agree re sales of new chains!

Second crazy-legs and a ruler.
24 links on a new chain 12",
12 and 1/16th" OK,
12 and 1/8th" replace.Posted 1 year ago # -
Yep, I've always measured the chain with a ruler too and change at 12 and 1/16th, cassettes and rings last ages (almost forever) that way, learnt that one back in 1993 the first time I also had to fork out for a new cassette and they seemed a lot more ££'s then than they do now

I was given the BBB jobbie at work to use on customers' chains. It went to the "bits never to be used again" container when a brand spanking new KMC chain was shown as worn completely. It's the ruler rule that's rule!

i have found digital ones are the best. there is some good advice on the kmc site. http://www.kmcchain.com/index.php?ln=en&fn=service#5 could be the way you ride. do you get out of the saddle allot? from being stationary? just a thought.

Ditto to what crazy_legs says on overrecording wear,
Take one brand new 10s Shimano DuraAce chain, fit to bike(with spanky-new cassette), Now measure with most chain checkers....
.... Invariably, they'll tell you that you now need a new chain!
