Quick chain question

1/8" chain is used on most single-speed bicycles, and bicycles with internal gearing.

3/32" chain is used on derailer equipped bicycles that have more than 3 speeds.

Exactly, so why does everyone seem to think a thinner chain is stronger these days?

A 1/8" can move side to side more on the sprocket, putting uneven loading on the pins and therefore more wear on the rivets. This is 100% fact maybe.

To add a bit more 100% engineering fact, the longer pins also allow more leverage and therefore flex leading to a 0.2% increase in run-up distances.

Just for those who are interested:

I used to run a KMC Koolchain 810 (the slightly smaller version of the common 710) in combination with the Rohloff tensioner on the Skye.

It worked out with no issues.

Might be helpful for those who won't rely on other chains than the Koolchain, just like me :)

Do they? Only difference is roller and pin width, plates are identical.

But anyway, Z610HX is all good.

Maybe between the z610 and 510 yes... But not compared to other chains.

I'll be very very surprised if my chains plates were anything smaller than triple the width of the kmc chains.
