Reviews over the

KMC X12

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.
