No but I was measuring a new chain with no freeplay in it.

The problem I have with the DRC gauge is that it appears to be trying to measure the length of 11 x links + 1 roller thickness which theoretically should give a length of 184.6 mm for a 525 chain. However, 0% on the gauge appears to be a length of about 185.6 mm meaning that I get about 1 mm of freeplay on the gauge when I fit it to my chain!

Something's not right but I can't figure out what that is :084:

I use a similar gauge for pushbike chains (Lifeline Chain Wear Indicator) but it's a go/no-go gauge with 0.75% and 1% wear checks, perhaps the markings on the the DRC one indicate remaining chain life  :187:

This gauge sounds like a silly toy.

For the newbies: First sign of a chain being on its way out is when it needs adjusting. A knackered chain has tight/loose spots so won't adjust to uniform slack. They never wear evenly, check at various positions on its length.

Still uses the original chain  and rear sprocket on my 800 XCA 2017.  Changed the front sprocket to 17 T at 3500 km and at the same time installed a Cobrra Nemo 2 chain luber.
The bike now shows 22 000 km and according to the DRC Chain Checker, wear is close to 0%.
Both front and rear sprocket looks like new.
Will be interesting to see how long they last.

I've just done a test with the DRC chain checker on an old chain which I measured to have 0.4% stretch using a very accurate vernier calliper measurement.

The problem with the chain checker is that it is very difficult to judge where it contacts the roller to read off a measurement. On the old chain I tried, if I didn't know better, I could have convinced myself that the measurement was anywhere between 0.25% and 0.5%; in other words, between a half worn chain and a totally worn out chain. I therefore don't think the gauge is accurate enough and I for one will be sticking to using a vernier calliper!
