Sprocket and chain work very well and shifts fine

Shifts very smoothly

Pros & Cons

Nothing wrong with KMC chains in general. Opted for the silver version.

Pros & Cons

After having basically always ridden Shimano chains for a long time, I have been riding KMC chains for several years now and to my complete satisfaction, including this X-12. The blue effect is nice (has to match your bike) and remains well visible (I was afraid it would 'wear off' but it doesn't.

Pros & Cons

Having broken a 12speed KMC chain on my wife's light e-MTB last year AND a dedicated e-mtb 12 speed KMC chain (KMC e12 EPT) on that e-MTB AND last weekend my 11-year-old son broke this 12speed X12 rainbow chain I no longer trust these chains. All 3 aforementioned chains had only been cycled with a few times, had a zgan cassette and sprockets and they did not break near or on the missing link. I am switching back to Shimano 12 speed chains which I have had much better experiences with.

Pros & Cons

This is my second channel, and I'm very happy with the quality and rendering. Nothing to envy from other channels.
