Repeat Buyer

This has to be the best looking and performing chain I have ever used! Runs quiet and long lasting!

Function and fashion

I've been using this chain for a lot of rides for the last 2 weeks. It has shifted perfectly and still looks great.

Cool Bling

KMC chains are the bomb, when it comes to strength and wear. I’m running this “aurora” beauty on my Rise eMTB, with Sramano drivetrain. SRAM X01 AXS and Shimano SLX cassette, which came on the bike. Works perfectly! KMC chains are the only ones I use.

Great 12 speed chain

It looks amazing on the bike, shifts as good as the stock chain and seems to be wearing better as well. I found my new go to for chains!

KMC 12spd Aurora chain

Great looking chain with performance to match. Great addition to the SRAM XO kit on my Evil Following, definitely will become a repeat customer.

Features

DOUBLE X-BRIDGE

With Double X Bridge construction, our chains increase shifitng precision and shifting speed. Smooth, fast, and accurate.

INNER & OUTER CHAMFERING

Ramps specifically engineered to engage with your chain rings and cassettes quickly and provide smooth shifting.

TI-N COATING

Titanium nitride is a chemical compound of the elements titanium and nitrogen. The ceramic material of typical golden yellow color is characterized by very high hardness and corrosion resistance. KMC’s special Titanium Nitride coating not only looks fantastic, it has an ultra-smooth surface and is extremely durable.

HIGH PIN POWER

Shave grams in every link, hollow pins are used in all of our super light chains.

ECOPROTEQ COATING

The latest milestone of KMC in rust protection. The non-toxic EcoProTeQ treatment doubles the rust resistance compared to KMC‘s RB anti-rust treatment. The advantages of the very smooth coating are maximum rust resistance, low noise and a great look.
