How long until we see this on brake disc rotors and wheel rims?

It looks like it's quite heavy so a coating would work well.

Maybe not so good for disc rotors and rims after all:

'...while measuring wear on their platinum-gold, an unexpected black film started forming on top. They recognized it: diamond-like carbon, one of the world's best man-made coatings, slick as graphite and hard as diamond. Their creation was making its own lubricant, and a good one at that.'

Bearings, on the other hand?

But, just think how long they'd last!

Ahh, but which are better; graphite coated disc brakes, or graphite coated rim brakes? We need an online discussion to thrash this one out!

Can't you let us dream?

ChrisB200SX - chain and cassettes sounds like a good use-case if the coating is slippery. I wasn't sure from the article whether the coating was generating its own lubricant or whether they were talking about a different coating.

I think it will be a long, long time before we see such a coating on bicycle components.

It simply comes down to cost, it's not worth putting such a coating on bike components.

For applications such as high-speed bearings in gas turbine engines, it's a very good idea.

Hmm, Pt-Au chain coating sounds good, maybe should be added to Dura-Ace cassettes too?
