I've had one of these for years
but following someone mentioning here that 11speed chains should be changed at 0.5% (and that checker only has 0.75% and 1.0% checks) and having acquired the first 11spd bike recently, I thought I'd better invest in one of these
Slightly concerned to read the instructions with the latest tool that 10spd chains should be binned at 0.5%. God, how many thousands of miles have we covered between us with slightly overworn chains ?
Anyhow, the old checker isn't showing even 0.75% wear on my bike's chain, yet the new one is showing it at 1.0%.
That's a bit crap.
I'm inclined to believe the original tool is the more accurate as there's no moving parts.
With regard how I'm going to confidently check the 11spd chain for wear I reckon I'll simply knock 0.25% off the reading I get with the new checker.
Does that approach seem sound ?
