Author Topic: Thinking of Going Deeper Counterfeit Frames – UPDATE and Fund Link  (Read 37506 times)

After posting the “Candid Look Inside the Replica Frame Industry – What a Chinese Insider Told Me” thread, I’ve been thinking about going a bit deeper with this.

I’ve already bought the X68, and I had planned to get it scanned—but didn’t in the end, mainly because I was being tight with money. That said, I’ve been speaking to more sellers, asking tougher questions, and trying to really understand what’s happening behind the scenes—because the reality is, most of us are flying blind when it comes to buying these replica frames.

Everyone claims their frame is “top quality,” whether they’re a seller, manufacturer, or somewhere in between. But the truth is, we don’t really know. We rely on a mix of user reviews, scattered posts, and a bit of gut instinct—and even that is hit and miss.

These frames typically sell for around $700 USD, and the ones marketed as “premium” or “top-tier” are closer to $1,000 USD. No doubt they’ve improved over the past five years in terms of finish and design, but there are still obvious issues. Sellers are now offering 2- or 3-year warranties, which on the surface seems reassuring—but when things go wrong, you’re the one covering shipping costs, customs delays, and lengthy conversations with someone halfway across the world.

One thing I’ve been digging into more is the topic of layup and construction. Sellers often say the original CAD files were “acquired” and moulds were made—especially in the case of popular models like the SL8. But what does that really mean? Is there an actual layup schedule being followed? Are the fibre orientations correct? Are cutting patterns even remotely similar? And is the carbon comparable to what brands use—or just generic Toray or something cheaper?

It’d be fascinating to see what these sellers are actually working from. I’ve asked for photos, cutaway samples, testing footage—anything that could serve as proof—but answers so far have been vague at best.

That’s why I’m planning to buy another frame—this time with the intention of having it properly scanned and analysed. I don’t just mean a once-over. I’m talking full inspection: wall thickness, fibre layup, internal finish, bonding, consistency. One consideration is having a CT scan done here in the UK, which would give us a clear view inside the frame without damaging it. That’s likely to cost around $200–250 USD, but it would be a huge step forward in transparency.

Whether it’s CT or physical teardown, we’ll find a way. I think that kind of deep dive could offer genuine value to people on this forum.

To be clear, I’m not doing this to promote counterfeit products. People are going to buy these frames whether I say anything or not. But if they’re going to do it, they deserve better information—something more than a Telegram screenshot or a factory promise.

A few people in the past have said, “Chuck Patrick a couple of quid so he can buy a frame.” Just for the record—I’m not asking for money. I’ve got two bikes already. I’m not rich, but I’m fine. If I need another frame, I’ll buy one. That said, if someone genuinely wants to help support the idea—just to fund proper analysis and testing—drop me a DM. If 300–400 members each put in £2, that’s the price of a coffee. Nothing more. Just something to consider.

I’m all about saving money and getting good value myself, but more importantly, I’m about helping people make smart, informed decisions. If I can contribute to that with what little knowledge and experience I have, then I’ll do my best to make it worthwhile for others.

Always happy to hear thoughts—especially from senior members or anyone who’s been around long enough to cut through the fluff.

I'm game. Dm me a funding link...

FWIW, though, what we'll know about is one frame. I'm not convinced that there's a single source for the sl8ish bikes, although I doubt there are many.  And I'm not sure ex cure you'll be able to tell a whole lot about fiber quality and orientation of plies, but maybe I'm wrong. But as you and Serge and some others have said in the past, I think that we're at a point where its pretty common knowledge about how to lay up a serviceable and lightish frame. If there's any "special sauce" its likely in unique orientations that are at best marginal gains, and lighter but more fragile material. And that may all be a myth as well.
What would be really interesting would be to scan an actual sl8 pro/expert and an x68 to compare. But now you're getting into needing youtube revenue to fund that sort of endeavor. And who knows how many people care? The avg. cyclist looks down their nose at these frames, making jokes about dental insurance and whatnot.
The issue arises with frames from sources that have nothing to lose. Tantan is a biggish company that has skin in the game. I suspect that they at least vet their source carefully if in fact its a third party frame. An ali storefront is another matter.

Cnasta

I'm game as well!

Would be intrested in what frame you are going to scan/tear down. The x68 would make sense, given the number of replies on that thread and the hesitation that comes from questions about weight/safety (exploding forks, too light weight, etc.). Got a plan for any particular frame?

Hey Glepore,

Thanks for your thoughts — I wanted to add some info I’ve been given about these frames.

Regarding the carbon fiber layup, there are industry standards. The model drawings we have actually come from an original factory, but really they’re just very precise 3D models — they don’t show the actual carbon fiber layering or fiber orientations.

The real difference lies in the carbon fiber factory’s actual capability. For example, factories use carbon fiber sheets and adjust fiber orientations (0°, ±45°, 90°) to get anisotropic mechanical properties. Areas needing stiffness like the bottom bracket and head tube get more longitudinal layers, while shock-absorbing parts like the seat stays use angled layers.

The drawings themselves aren’t hard to get — in our circle, if you’re willing to pay, you can get them.

But every factory has its own stacking method and uses different carbon fiber brands, so there’s no way all market frames have the same layup. Also, there’s definitely no real “T1100” carbon fiber out there. We use M30 from Korea, which is just behind Toray in quality. Those “T1100” claims are just marketing hype — our weight-to-stiffness ratio speaks for itself.

Adding to that, it’s clear the information is widely available and you can buy it for genuine frames. What really matters is the expertise of each individual factory that gets the job. It’s not just one factory — it’s multiple factories, and some are better than others, producing higher quality frames.

From what I can see, the info is easy to get hold of, so it really comes down to who’s producing it and the ethics behind it. Some factories focus on quality and craftsmanship, while others just want to churn out products and make money quickly.

Also, I know there’ll be some people reading this who might be sceptical. Honestly, some might think I’m crowdfunding just to get myself a free frame. To be clear, I’m not desperate to get $750 for a frame. I’m just genuinely interested in digging a bit deeper.

Maybe not scanning the X68 exactly, but at least getting a frame made, sending it away for analysis, and seeing what happens. Could be fantastic or could be terrible — who knows. But the store seemed quite keen and confident about doing it, so that’s encouraging.

Just thought I’d share all that to add some context to the discussion!

Could  always do two frames for comparison 😂
Can’t be arsed to strip my bike down though lol.
I’m not worried about the time but two frames is ££££
Probably looking at £1500gbp including scans
End up finding out Tan Tan frame is doggy doodooo and let see how they repsond to that.
Probably say the expert is not an expert 😂

Exactly what I'm thinking.

Well Glepore  we’ve definitely got plenty of lurkers watching — and with the insight I’ve managed to gather (which, granted, will always have its skeptics), I think this kind of project could be genuinely useful.

It’d be nice if some of the lurkers piped up too — they’re often the ones messaging me privately asking, “So where’s the best quality place to buy a frame?” 😅

Definitely worth considering stripping down the X68 to avoid having to buy a second frame — a direct comparison would obviously be far more insightful.

Not sure what the best platform for donations would be aside from PayPal 😂 but I’ll look into it.

I’ve seen a one guys on YouTube do a review on a Trek and an SL8 , but they’ve been pretty underwhelming — just side-by-side comparisons with no real depth or analysis. So there’s definitely a gap for something more detailed.

As a man of science, I also think that 2 frames is the go to not only check for they layups, but also reproducibility. At least to some extent.

BeR

Indeed. Quality can vary a lot between two frames from the same seller. We have to remember the "cheese frame" from Lightcarbon or even Winspace.

Unfortunately, I doubt that we can tell the serious of a seller by analyzing only one frame. But it is a beginning :).

A good friend of mine (actually my business partner too) just bought a Velobuild 268 and opted to get the frame in raw (unpainted).

Looking at it up close, IRL, it's nothing at all like an SL7. Being raw probably doesn't help, but hot damn it's really rough around the rear brake caliper mounting points, not to mention it has a completely different thru axle design (fake Mavic quick release thru axles were provided), making it impossible to use ordinary thru axles.

Also a genuine SL7/Allez Sprint seatpost does not fit into the frame, and even the way the rear seatstays attach to the frame are different to an SL7.

I also noted that the rubber flap over the seatpost sticks out past the frame, and the seatpost clamp has much sharper edges vs. the SL7 original.

IE/TLDR: It's definitely not a super accurate replica, and the changes made to it aren't any better.

That said, this SL8 frame in question. From what I've read so far:

- The replica frame fork is lighter than a genuine SL8 fork (some reports of it "exploding" too). Why is this?

- Not sure, but does a genuine SL8 seatpost fit into the replica SL8 frameset? If not, then that's quite revealing.

Ultimately, no matter how much research you do, I think the final end result will be the same. IE: It's way cheaper than a genuine SL8, it's good, but it's not better.

Well the 268 was never mean to be an sl7 anything. It's based upon the 168, with the goal of making a more aero bike (in appearance at least). The 168 itself was heavily inspired by the sl7, but not a direct copy or counterfeit. The engineer probably had one on a table next to them, but they definitely didn't rip it from a cad file or 3d scan.

JustinFox

Fair call, ignore everything I said about the Velobuild then, but instead focus on what I said about the SL8 rip-off.

IE: After all the testing has been done, the findings will reveal that it will be good, but arguably not as good as a genuine SL8 and most definitely not better than a genuine SL8.

I’d actually disagree — the interest in counterfeit frames has always been there, it’s just that people are now more openly talking about it.

I understand it’s a sensitive and divisive topic. Some will agree, others won’t, and yes — it’s technically illegal. I’m not denying that. Is it in the true spirit of the forum? Maybe not entirely. But the reality is that the demand is huge, whether we like it or not. And with demand comes discussion.

That’s the value of threads like this — they spark conversation, debate, and hopefully, awareness. I’m not here to promote counterfeits, but if people are going to explore that route anyway, I’d rather they be informed and aware of the risks — safety being a big one.

It’s a bit of a catch-22. You either bury your head in the sand and pretend it’s not happening, or you engage with it in a way that helps people make smarter decisions.

I appreciate the intention, but I think your proposal would be interesting if applied on a large scale, which would mean examining more models/frame manufacturers and not necessarily only replicas/counterfeits.
I follow these discussions with interest and the one about the TanTan X68, but for example I bought a Spcycle R088 frame (because, even if it is clearly inspired by the Tarmac SL8, at least it is different and has its own identity) and obviously I would be more interested in having the quality of this frame and/or other frames produced/sold by Spcycle verified (from what they say it seems like they have their own factory, but from what I understand, you have to take with due caution what is reported by the interested parties).
So, in conclusion, I would rather "invest" resources to analyze/promote "proprietary" frames and offer a potential buyer feedback on the manufacturer....but I think it is very difficult to achieve all this.

PS: an "indirect" way to evaluate the quality/reliability of an OEM frame could be to do a search to see if it is sold by some brand.
At the beginning of my search I had identified a Workswell frame that I could not buy because it was already sold by a "well-known" Italian brand (at least for Italians)....this leads me to think that the frames produced by Workswell are reliable, even if obviously they cost a little more than $700.
