Recently, JOM of the Gravel Cyclist crew devoted a bunch of time, swapping wheels with cassettes by Shimano, Campagnolo, and SRAM, between bikes fitted with those systems to determine what works, and what doesn't.
During this lengthy exercise, he learned of the existence of KMC's X12 chain, one that promises to run reliably on every 12 speed drivetrain circa 2024.
In this video, JOM presents his findings with over 500km on this chain paired to SRAM eTap AXS Force... and some kilometres with the chain on a Shimano Ultegra 11-30 12-speed cassette.

You just can’t leave well enough alone 😂. Good to see you in the States 👍

Someone has to tinker with all of these parts :)

I run mine on my Force 1x, very happy

@GravelCyclist 2 месяца назад

Nice, thank you for chiming in, was interested to hear how the X12 performed on a SRAM 1x system.

@hardmtnbiker 2 месяца назад

I’ve been using KMC chains on all my bikes. For me it’s a better choice. I wax my chains with Silca and that keeps everything nice and smooth. I only have Shimano derailers but different cassettes and chain rings.

@trialmx 2 месяца назад

My first thought was " Yes, I do need a gold chain".

@GravelCyclist 2 месяца назад

100%!

@jamesenloe2791 2 месяца назад

Fact: gold chain adds an additional 3-5 watts

@chrisscott8362 2 месяца назад

yes!

@hansschotterradler3772 2 месяца назад

Thanks for the video. It appeared that the shimano cassette offered slightly smoother shifting than the sram cassette.

@GravelCyclist 2 месяца назад

For certain. Bear in mind that Shimano cassette was paired with a SRAM Force drivetrain,. I have yet to try all Shimano, I expect that will be near perfect.

@bengt_axle 2 месяца назад

Are the plates on this chain beveled, so as to engage the tooth on the cassette that sticks out a bit, and still shift smoothly going down the cassette?

@Thomas-fy9yc 2 месяца назад

Couple people in my bike group ran them on various AXS setups, and they all ditched KMC and went back to SRAM as they seemed prone to drop chains on 2x systems.

@GravelCyclist 2 месяца назад

No chain drops yet, no changes made to front derailleur setup.

@sandswan 2 месяца назад

@@GravelCyclist Funny - I had two dropped chains at Mid South with the flattop SRAM chain 😂 Thanks so much for testing this. I'm really looking forward to buying one of these KMC's in gold. My chain is the last bit of kit on my ADHX still in silver!

@Ingrimmsch91 21 день назад

SRAM has notoriously poor front shift … a dropped chain is normal for them

@RicardoRocha-lg1xo 2 месяца назад

Good to know they work!

@DogDude4all 2 месяца назад

My experience using a non flattop chain on SRAM 12s road was that it shifted fine, but felt like pedaling through broken glass. I assume this was because of the smaller rollers on a cassette intended for larger rollers.

@GravelCyclist 2 месяца назад

I can assure you there is none of the pedaling feeling you are describing. SRAM Rival Flattop chains are certainly cheap enough (and good enough) that I expect KMC's option won't be adopted in a broad manner.

@michiganstate149 2 месяца назад

KMC seems to split the difference between Sram and Shimano. Works on both, not impressive on either. Good option for some.

@ianthedondaws7559 2 месяца назад

I always prefer a kmc chain..👍

@GravelCyclist 2 месяца назад

Looks fab in gold 👌

@sandswan 2 месяца назад

The US KMC store states this on their website: Compatibility: SRAM Eagle, SRAM Eagle AXS, Shimano, and Campagnolo Bicycle Type: MTB, Road, Gravel, Cyclocross *Not Compatible with SRAM eTAP and Flattop You're testing it on the SRAM Force Wide and it seems fine... any reason why it wouldn't work on the D2 SRAM Force 2x ?

@GravelCyclist 2 месяца назад

I based my testing on what is displayed on the chain packaging, I hadn't checked the website disclaimer in some time. You can see how it performed here, but I suggest you use at your own risk. SRAM may not recognize any potential warranty issues if you use this chain. Good luck!

@markreams3192 2 месяца назад

The shifting is not impressive in this video. I’ve used KMC on Shimano 11sp. While it worked, the shifting is not as crisp as a Shimano chain. The Shimano chain lasts longer as well.

@GravelCyclist 2 месяца назад

In case you missed it, this is a Shimano 12 speed cassette, SRAM Force drivetrain, KMC X12 chain. I have yet to try it with an all Shimano drivetrain, which I expect may shift the best of all.

@ScottCopeland-yh9lm 2 месяца назад

They are my go to chain. Can you send me a free one. I’ll take 11 speed, oil slick or gold. Enjoy your day.

@GravelCyclist 2 месяца назад

Better talk to KMC about a freebie chain.

@0rangekick 2 месяца назад

the last time I bought a KMC chain was about 10 years ago, because it was cheap. Once installed, I checked it with my Park Tool chain checker and it indicated not the 0.5 or less, but it indicated 0.75 or more - and that's where I normally replace with a new chain. The chain was out of tolerance before I even got out of my driveway. BUYER BEWARE!!!

@GravelCyclist 2 месяца назад

Ten years ago is a long time.

@iamsamjackson 2 месяца назад

Where did you purchase? I know there are a lot of fake chains from KMC on ebay and amazon

@0rangekick 2 месяца назад

@@iamsamjackson I bought it from Amazon.... I've tried others too, any chain made in China fail my Park Chain Checker. A new chain whether it's Shimano, SRAM, Wippermann Connex, Campagnolo, should read zero straight out of the box it came in.

@iamsamjackson 2 месяца назад

@@0rangekick KMC is TW based. I would be surprised if the chain you ordered on Amazon was genuine. KMC manufactures some of shimano's chains, and generally produces high quality products.
