Has anyone had any experience of KMC chains failing prematurely? I have a 9 speed Sora equipped bike permanently on my Wahoo Kickr. The groupset is in good condition with no parts especially worn. The drivetrain is kept spotless and dry lubed regularly.
My old KMC X9 chain basically exploded about a month ago with countless broken links. I put it down to wear and tear, purchasing another KMC X9 however that chain did a similar exploding trick tonight and upon inspection there are at least 13 cracked links. It's done less than 100km indoors.
I've used KMC chains for years with no problems but this really puts me off. Thankfully I was on the turbo so no harm done, but outside in traffic the result could have been very different!
I'm sure the retailer will warranty replace it but before I accept a replacement KMC I thought I'd canvass opinion here on possible causes?
