I'm familiar with DLC. (Diamond like coating).
BMW put it on the cams of their S1000R series bikes. They can make the cams much lighter that way.
The coating fails all the time and destroys the top-ends.
So that's the DLC on Cam shafts in their top of the range sports bikes. Using the best factory processes.
I can't see the DLC on a chain being applied so well or of the same quality.
The marketing blurb looks like the same that you see on Diamond tipped Drill bits. Those that promise so much for £10 and they're all blunt within 30 seconds.
