What our customers are saying about KMC X12 Aurora chain

This high-quality KMC bike chain is praised for its durability and precision. Users report exceptionally smooth and superior shifting performance, often better than Shimano or SRAM equivalents. Its lightweight design and stunning, iridescent colors that look beautiful in the sun make it a top choice. An excellent, reliable, and good-looking chain for any high-performance bike

The number 1 choice as a replacement for shimano

On my mountain bike, as a replacement for an XT chain and then an XTR chain that didn't even last 500km in the mud, I'm trying the KMC...super performance, great feel. WARNING: durability is only rated 3/5 on the box. I don't know what to expect, but I figure it would definitely be more durable than the XTR...and after 400km it still looks to be in great condition!!!

Reliable & dependable

High quality chain with a bit of colour

Mark

My first KMC chain, bought on recommendation from my mechanic, and to match my frame colour. Road yesterday on my 12 speed Dura Ace groupset for the first time in a race. Shifted well and ran smoothly. Too early to report on durability but my experienced mechanic swears they're a better buy than the competition.

Great seller

It is not the lightest KMC model but we are at the top of the range levels of other brands. Smooth shifting and no problems. It's the second one I've changed and I'm very happy

KMC is always synonymous with quality. Durable and precise, as well as beautiful. 100% recommended.

Richard

I've used KMC chains for sometime, my impression is that the shifting is of a superior level than Shimano or SRAM equivalents. This chain is going on iridescent colour frame, so will look superb. Bikeinn pricing can not be matched. With the demise of Wiggle shipping to Australia, Bikeinn have filled the gap for me ;-)

Good product
