I've just received a counterfeit 12 speed KMC chain from Aliexpress. I provided them with photos and links. Also 75% "worn".

Good to know if my video was helpful for you. If you could forward the video to your cycling friends that would help spread the message about these poor quality/dangerous parts. I've had a similar issue with trying to claim through AliExpress for a non-delivered item, I think their system only has one outcome 'rejected the claim'. Having said that, the item did eventually turn up after 2 months despite it being on a guaranteed 15-day delivery time. I now never buy big-name branded items on AliExpress. I have had success with lesser-known Chinese brands such as Sensah.
Counterfeit components are a huge issue for us in Thailand. I try to buy from authorized dealers in Europe for this very reason. Shimano fakes are the worst offenders!
This seems to be a worldwide problem, although this is the first time I have categorically identified a counterfeit chain. Although, as you mentioned Shimano chains, looking back, I think I probably bought a couple of counterfeit 9-speed chains. Judging by the wear rate of my genuine KMC chain it is definitely worth paying to be sure of getting genuine items.
At 6.00 the close up the actual outter links look bigger in the fake to the real one, the heads look alot wider! Unbelievable even at it with KCM that middle cut being right to the edge though thats very concerning!
Thank you very much indeed for this detailed video. The packaging of the fake chains has improved. I just bought a fake since the packaging looked kosher and does not have most of the issues mentioned here. But the main chevrons on the blue background fade out in the real packaging but stop abruptly with the fake and this chain that I have purchased likewise. Also the inner plates are not chamfered. Thank you for pointing that out. I will check the length soon.
Thanks for the feedback. Yes, they probably put more effort into nice packaging than making the chain 😁. It is getting difficult to buy guaranteed non-counterfit chains. I now tend to go to reputable sellers (like Amazon 😂) so if I do get fakes, I can at least return them and get a refund.
Just got what is a fake kmc chain, skipped really badly, just swapped it with what I think is a genuine kmc chain all fine now. Your video explains it perfectly
Just used your video to check if my two s KMC X bridge chain were not fakes. They were not and met all the criteria as per your real one. Many thanks for an excellent video. I have been burnt by some Shimano chains in the past, purchased from Amazon. Only realised after they wore out after 4-5 months , by which time they had also worn out 2 cassettes and two front chain rings.
I feel for you, been there. There seem to be more fakes than real chains. I opt for KMC because the real ones are great and not faked as much as Shimano.
Ordered one, packaging looked legit, but the chain didn't have that weird xsp print, random 1 and 2 numbers, and was uneven, deeper here, barely there there. It was made in 2021, so maybe they looked different from what is on the official site now, but I returned it, idk🥴
I would guess the reason these fake chains stretch so readily is that they must be made from the wrong type of steel. There are literally 100's of differrent steel alloy formulations and for a hard wearing chain that resists stretching I would guess a high tensile quality steel would have to be used. Softer steels, which I would guess these fakes are made from, will wear and stretch much more readily.
Strictly speaking the chains don't stretch, they wear out. That is the clearance between the pins and holes increases which gives the impression of stretching. The selection of the material, coatings and lubricant affects how quickly the chain will wear. This may be exacerbated by initial slack tolerances. It's nice for me to know, that you know that steels are 'alloys' 😊😊😊
I got caught out buying a fake kmc chain off Ebay last year .. the chain snapped first ride out in 3 different links while i was 8 miles out on a forest trail as you can imagine i was not amused
@@Lord-hoboco777 > you have my sympathy, I had one break too but it did have a few hundred kilometres of use. If you're lucky, they just wear out quickly, looks like you are not lucky.
@@FiveMinuteVelo the only luck i did have that day was i only had a few cuts and bruises and someone came by on an Ebike after a mile of pushing my mtb and gave me a tow the rest of the way back to civilization i got a full refund off the Ebay seller so i was lucky in that way
The wear indicator tool is useful but not without its own problems. For instance the indicated tools I use measure the total wear, this includes the main bushing wear and the roller wear. There is an argument that roller wear is irrelevant and should not be included. Some measuring tools do try to take roller wear into account. p.s. the rollers on not really rollers - they don't roll - they are really just plain bushes.
I got fake brand name MTB grips in the past. I won't order parts from those big distributors to begin with. That doesn't exactly resolve the potential problem. Fake parts do make it inside respected retailers unbeknownst to the owner. It happens when ppl try to save a dime or make a dime. The customer must always be on top of it by staying educated and on the ball. Return parts when it happens. Don't use it anyway. The problem will run more out of control if nobody does anything to push back.
I just was taken with a counterfeit kmc x12. The chain lasted only 3 hrs and lost 3 rollers and was stretched beyond 75 percent. I would love to share photos
Terrible, never had one that bad. If you use Instagram you could share photos on there and #fiveminutevelo. Alternatively you could send the photos and a description to me at fiveminutevelo@gmail.com and I will post them on your behalf. Did you get any recourse from the seller?
I have received a counterfeit Shimano chain from ebay and Aliexpress. Im sticking to my LBS from now on. Too critical a component. I feel dumb trying to save a few bucks when my bike is fairly expensive.
Good call, I too have started to spend more time on buying good chains rather than cost savings. Beware though, I have a friend who bought a couple of chains from an LBS and they turned out to be counterfeit; he did though get them exchanged for genuine chains after the LBS had realised that they had been duped into buying counterfeit items.
I've had a KMC (or "KMC") 10-speed chain snap on my 3 month old Brompton T Line that I fitted when the bike was brand new. 5 weeks later and still recovering from my injuries, I've realised the chain actually snapped on a normal link, not on the joint link.I now need to inspect the chain further to see if it is genuine or not. Thank you for your video!!
I'm really sorry to hear that you were injured. I hope you get a full recovery soon. I'd be interested to know what the outcome of your investigations are.
Just realised I'd bought 2 fake chains last night, put a new drivetrain on the MTB and it wouldn't mesh with the narrow wide chainring. I've had the other one on the road bike for 17 months and it was a little noisy, I put it down to the Sun race cassette. I've since ordered 2 XTR chains from a reputable local online store, I'll stay away from eBay from now on.
Turns out the fakes I bought are stamped just like the originals but the packaging is fake as per your video. I haven't been using one for 17 months, turns out I bought these in November and I have a new one in the shed. I've complained to eBay. Your chains seem to come pre worn, mine are the other way around, they're too tight, just won't work on a narrow wide chainring. I'm also not so sure my old chain was genuine, it has no chamfering.
The manufacturers (genuine) change features from time to time and from different levels of chain. Hence, the lack of chamfers is not necessarily a giveaway. Often it's difficult to tell whether a chain is a fake or not? However, being aware that the problem is out, there is halfway to solving it.
It seems my X8 is fake. Got no space on the KMC corp and "perfect" X on the chain. Came in greased though. However, it's shifting well and not worn as bad as yours. I also got it for $5, hoping that it's old stock, but I knew I was risking that it would be fake. Eh it's only 5 bucks and it's doing it's job so far so no biggie until it breaks early.
Also if the chain wears rapidly it could destroy your chain rings and cassette. In which case it could be a false economy. If it works for you though fine, just keep an eye on the wear.
@@al-du6lb > it's difficult not to buy fake chains through Amazon, particularly if it's a non-amison seller selling on Amazon. I have bought what I believe to be genuine KMC chains direct from Amazon. However, overall I think it is very hit and miss.
I bought a fake KMC chain on E Bay, it measured.025 out of my the box. I wanted to see how long it would last and it went two hundred and fifty days for me, I ride four miles a day
Maybe not quite! I don't know about the rest of the world, but here in Europe we can't buy direct from KMC, only their official sellers. Where I live these are just ordinary LBS. Admittedly you're much less likely to get the fake chain through this route but it's not guaranteed. I know someone who bought two SRAM through such a shop and they turned out to be counterfeit. It turned out the shop obtained them through an intermediary distributor (quite normal practice) and they had some how got hold of a batch of fakes.
@@FiveMinuteVelo I did it on a fake 11s 701 chain I got off Amazon and took a lot of close ups after I split it apart. You’d be amazed at the difference in quality and manufacturing and details that go onto a genuine Shimano chain.
@@GNX157 I have not looked at Shimano chains, never really used them. Biggest issue seems to be getting hold of a genuine chain, the market seems to be flooded with fakes. I even know someone that bought a couple of chains from an LBS and they turned out to be fake, despite the seller swearing that they came from a reputable distributor.
I agree to a large extent. Chain checking tools have their place but you need to know their limitations. Also, believe me, using a rule is not a skill that everybody has.
In my opinion they are all fake products. Even the one you think is genuine seems not to me. The KMC stamping on the links is way to bad quality, like blurry. The real KMC chains have very crisp markings and perfect positioning on the links. Non of your chains have that. There is also a different font style used for the "S" of "11 Speed" on the front of the packaging.
I wouldn't be surprised, as some of the fakes I've seen since making this video have been pretty good. For me though, as a user, how long the chain lasts is important. What I think is the genuine chain, measured up well when new and lasted quite well. I did also look on the KMC website that has a section on how to spot a fake chain. Based on the information KMC gave my supposedly genuine chain didn't ring any alarm bells.
Both your chains are fake. The one you believe to be genuine is also fake, but a better made one. A quick look at the outer plate chamfers are not proud and distinguished. That's an immediate tell tale sign. Next, the branding imprints on both are bad. Genuine ones are crisp, thin lined and really, like really clean. Go get a set from a local approved dealer, pay the retail and compare.
KMC chains being very cheap for what they are in comparison to some of their high end competitors, incredibly good value for money! Who cares... Let's fake em anyway 😣
