TomBest chains. All I have ever used and never any complaints.
Mr GabrielNew, authentic, keeps my Argon 18 fast
AlIf a chain is good, there's not much to say. This chain is light and strong, and is a good chain.
ScottLight, strong & silky smooth gear changes. Just what you expect from 1 of the best chains you can buy. Merlin were the cheapest by a mile at the time of purchase too 👌
MR G RTried and trusted chain. Easy to fit with supplied missing link. Previous chains lasted around 3,800 miles before 50% worn so happy to buy again and again.
Mr AnscombGreat chain smooth quiet. Have always used this model of chain and have never had any issues. Highly recommend.
SeanGreat chains. Never had a problem with KMC in terms of breaks or shiffting issues. Longevity is pretty good for such a light chain.
Mr SumerlinI have been using KMC's X11-SL chain for several years now (2-3 per year). No chain lasts longer IMO...and it's a gorgeous chain too! And you can't beat Merlin's price: $15-20 cheaper than all other sites!!
Mr SalterUsual KMC quality and suitable replacement for Shimano Ultegra.
russellSupersmooth, transmission and ride on my Campy Chorus system. I’m very happy with this replacement chain.
andrewGreat chain, used the SL for a few years and performs well
Nicholas EldredAn excellent chain. Good value for money. Easy to fit, runs smoothly.
RobHave been using this chain with Rotor Q chainring. Shift better than DA chain.
Steve HarrisonQuality chain, felt very smooth on first ride
Mr MorrisGreat chain at a great price!! Quiet and smooth, worth every penny, thanks Merlin
Mr LundstromGreat chain and easy to install, can’t go wrong with KMC great quality
JulioThis is the best chain I’ve used. Most be my 6th or 7th chain. I only change them when they stretch but the shifts are great. Really quiet chain too as long as it’s serviced periodically.
JoeteoFind this to be better than Shimano.
MervynCombined with a CS-R8000 cassette and now I'm ready to hit some hills. Great chain, if you are looking for a chain without any flash bling. Hardwearing. works well under strain and smooth shifting. KMC still are the best
Montreal BikerBeen using KMC EL chains for a while now but decided to try the SL - same great shift quality with my Shimano Ultegra groupset and saved around 10g over 106 links. Good price at Merlin, Very satisfied.
JoelGi love the color on this chain! brings a different bling to my chainset. super-light and shifts easily.
Mr BennettDoesn't run as quiet as the Campagnolo chain, but for those who like to mix 11sp cassettes, this works better. Works great with both Campy and Shimano cassettes.
Mr GunnarssonSturdy and reliable
G BradleyGreat chain, best price, great service. Replaced worn chain on Shimano 105. Easy to fit with master link, quieter than the old one.
EddieFitted on Campagnolo Super Record - easy to install - very crisp shifting - I will replace with the same when the time comes to change again.
JakoThe best 11 speed chain available.
Mr LimSuper light and strong chain. Highly recommended.
Mr JonesDurable chains for a great price. I've used KMC on my last bike and did not need to change after 11 months. I sold the bike during that time and the chain had not stretched. I ride 700 - 800 miles per month and it was still going strong! I'll never use Shimano chains again.
JakoThe best chain on the market. Super light and durable.
Mr chanFast delivery and shift better than Sram Red
BarbThird KMC chain for me - light & strong.
ClokeGreat Price, great service, speedy delivery. KMC chains are good value and seem to last longer than shimano chains.
MartyMy first KMC chain and seems to be quiet and smooth. Not sure about longevity yet, only used Campy chains in the past and thought I'd give these a go for a change.
Left Coast DaveThis chain is durable and light - I normally put 2000 miles on them before I notice the wear I could probably put another 500 miles before the chain wear tool would show excessive wear - the price at Merlin can't be beat
arnoldagdaganLove these chains!! Works well with my shimano and Sram 11 speed setup!! I recommend this product.
ClokeKMC chains are the best for weight, reliability, quietness, value. Merlin always offers competitive prices and quick delivery.
CloggsySuperb chain; I always buy KMC-SL chains & they are worth every penny.
Mr SmythI keep using these chains on all my bikes - they last for ages before chain check tool indicates replacement necessary - great value for money.
JenkinsAlways use KMC, work and last well. Split link makes an ease of cleaning and great prices at merlin
MortonAlways go for KMC chains and this chain like the ones before doesn't give me any reason to change.
Dr Anselmo FilhoIf you're looking for a replacement chain for your Campagnolo drives, you've found it. And even better than the original one! I have installed one of those in one of my bikes and 1500 km later, it seems like I did it yesterday. My chain checker even can't mark any wear (< 0.25% elongation). For my Drivetrains I'll use only KMC chains now.
Marek MSmall amount of chain noise, but I suspect it needs to break in for a 100km or so. Well built.
Mr LoughridgeSuper high quality chain at a great price. KMC's speed link makes this the easiet chain to fit with no long term issues. Will buy again, and can highly recommend KMC
Mr OsmanSuper light weight chain, great quality and strength
The Fastest VeggieLighter and cheaper than Campagnolo's own 11 speed chain and works faultlessly... No complaints!!
SamGreat value, KMC chains very reliable, light chain, great shifting.
Mr DansonKMC chains are Top Quality, I've used them for the last few years on my Shimano Dura Ace Groupset, and I'm now on the new 11 speed Dura Ace, Merlin always supply best priced goods and fast delivery. 5 Stars Merlin
Mr WoodcockJust replaced my Campy Record chain with the KMC SL. Seems to me that KMC make the better chain - it's noticeably smoother and I would recommend it as a replacement for any Campy 11 speed. Much easier to fit with the split link and no expensive Campy tool required!
Mr EllisKMC currently make the best chains going, just fitted this with a new Dura ace 11 speed drive train, and so much sweeter than the Shimano chain that came with the groupset.
Mr TranLightweight and very smooth.
