At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Let's be honest, you'll only be eyeing up the X11SL DLC chain if you have a posh bike and you want a flash colour-coordinated chain to finish it off. And if that's what you want, and you're okay with the salty £90 price tag (around £60 online), then the good news is that this is also a really good chain.

DLC stands for 'Diamond Like Coating' which is a hard coating KMC applies to the chain to reduce abrasion and wear. The X11SL has other high-end chain features too: the inner and outer link plates are all hollow, as are the pins, meaning that it's light for a chain at 240g for 116 links.

The chain's available with inner plates in a range of colours: black, blue, red, green, celeste, orange, pink and yellow. That means you can match it to your nice posh race bike and it'll look the business. It's simple to fit too, as it includes a KMC Missing Link 11-speed connector.

Once it's on, shifting performance is good and the chain runs nice and quietly with positive and reliable shifts between sprockets and chainrings. If you want to keep the coloured links looking good it's best to use a wax lube that doesn't pick up too much dirt. You won't need a wet lube, though, because you'll be leaving that bike in the garage if it's raining, right?

Is it better than a SRAM Red or Shimano Dura-Ace chain, both of which weigh about the same and can be had for less than £30? Well, not really. It is a lot prettier, though, assuming you keep it clean. That's the real reason to buy one over a pro-level chain from a major groupset manufacturer for less than half the price. It's your money, and your bike will look the business.

Verdict

Great looking high-spec colour-coordinated chain. Your best bike will thank you, your wallet not so much

I like KMC chains but I had one of the Titanium Nitrided ones.  The coating was on ly on the parts of the chain that can been seen.  When I took a few links out to fit it I found it was not on the inside of the links where they are in contact.  I felt this made the coating close to useless.  They need to prove this is not the case with this chain.

Wow, it has hollow inner and outer link plates too! I can see from the picture that they are slotted, but HOLLOW? Really?

Yes, hollow plates and pins.
And X11SL also has such hollow plates and pins.
But with almost half the price.

Calm down everyone, they are not 'hollow' in the typical usage of the term - in this case, they are referring to the slots.

Genuinely 'hollow' chains are under development at the MucOff-Sky-Rapha Skunkworks in Bournemouth. I have a friend who works in the carbon fibre/F1 industry, who reckons they have the laser-3D-printing gubbins to make something with an internal void that's still strong enough nearly productionised. Word is they will cost approximately £950 for 114 links (116 being clearly a silly weight issue, and no-one needs that sort of capacity wrap).

Will DLC on a chain cause any extra wear to the chainrings, cassette, derailleur pulley wheels?

The DLC makes sense... DLC coatings are used for MTB shock stanchions to keep then smooth and wearfree. DLC is even used by modeler's for crankshaft coatings on 2-stroke nitro engines.

Of course "DLC" varies significantly in quality...hardness, brittleness, etc, and of course, how thick/well it is applied. But what I want to know is, is the DLC strong enough to not wear out (on the inner pins, which is what causes 'stretch'; and on the ramps and rollers, which is what causes poor shifting)?

I haven't seen ANY closeup pictures of KMC DLC chains with thousands of miles on them. I'd be curious to see a long-term photo review.

EDIT: Is the Quick Connect link DLC too?

I've got the red version on my best bike and shifting performance is excellent... But of course I only got it to add a bit of bling and it looks ace  1
