KMC has had an all-black DLC chain in the line for at least a year. They say the “Diamond Like Coating” helps the chain last 20% longer than normal. The standard model is the X11SL DLC, part of their lightweight chain collection, and is all black with inner and outer plates all coated.
Now, they’re offering colored versions with the inner plates getting a different, colored coating. The Turquoise shown above was for a Bianchi sponsored pro team and will come in 11-speed only. The blue and red shown after the break will be offered in 10- and 11-speed versions. Price is €100.
