Yeah, let's see. I'm already considering TanTanCycling as Plan B....

Yeah, let's see. I'm already considering TanTanCycling as Plan B....

I like to keep my ear to the ground, and I’ve been chatting with a few sellers lately. It seems Chinese authorities have started cracking down on sellers pushing poor-quality products—apparently in response to legal action from (I’m assuming) Chinese nationals. What’s interesting is that these shutdowns don’t seem to be about counterfeiting, which you’d normally expect, and that in itself is a bit surprising.

Obviously, you’ve got to take this kind of info with a pinch of salt, but I’ve had a few sellers say similar things. Just last week, Tan Tan pulled the X68 from sale for a few days, but it’s already back up. YOHO Bike also disappeared for a week and has now returned. I’d genuinely love to know what’s going on behind the curtain.

I’m trying to educate myself and gather as much information as I can to better understand how things work when buying from these kinds of sellers—just so I can properly assess the risk. For me, the risk feels higher when buying from places like Taiwan Eisen, YOHO, Champion Bikes, or Airwolf. They all claim to be manufacturers, but let’s be honest—that’s mostly BS. Most of them are traders. Tan Tan, on the other hand, appears to be a legitimate factory (though whether they actually manufacture this specific frame is still unclear). They do have a reasonably good reputation, even if communication isn’t their strong suit. That said, I emailed Vivian about a custom paint request—I'd selected UD Raw Carbon Glossy—but apparently my order had already progressed to the point where they couldn’t change it. If they were just out for my money, they probably would’ve said yes anyway just to take more from me. So that gives me a bit more confidence.

As for the whole "how can they even make this frame?" question—well, I’ve looked through a bunch of patent info, and I haven’t found anything from Specialized in the US Patent Office that directly covers this frame design or anything close. So if there is any issue, it’s likely to fall more under trademark infringement than an actual patent violation.

I fully accept the risk I’ve taken with my purchases. But unfortunately, a lot of buyers don’t realize what they’re getting into. And I’m not really sure how dependable AliExpress is when it comes to refund claims—it’s definitely not eBay. So yeah, I hope you get your money back.

^ I've been digging around a bit. The sl8 isn't specifically  patented that I can find, but it appears that the sl6 or 7 is-D865574(search here https://ppubs.uspto.gov/pubwebapp/static/pages/ppubsbasic.html). Since most of the design elements of the sl8 are almost identical to the sl7, I suspect its not been patented as its covered by the prior patent.  Sworks Tarmac sl8 is trademarked. Whether Chinese authorities will enforce these patents remains to be seen, but I suspect that its enough to make folks nervous given Specialized pressure.

And here I thought I was the sleuth!

Well if there is no patent on the frame design we’ll
Can blame Tan Tan a lot more SL8 counterfeits than the old SL7
So maybe Specialized dropped the ball a little but patents from what I known can be notoriously difficult to register.
Anyway I’m so intrigued to see how this compares to my Gen SL8 I won’t lie I’m excited.
Feedback from everyone who has the frame has been positive part from the longer than quoted manufacturing times and lengthy deliveries.

Well I was quoted 10-18 days however Tan Tan cannot be held responsible for shipping times are these are estimates set but the shippers themselves.
Have they quoted a shipping service to you at all?
If so go to the shippers website

more than shipping, i wanted to know how long it takes to build the frame. i know roughly that shipping to eu with prepaid tax takes about 3 weeks. but they didn't answer me. mystery

Just think about the volume of emails and messages Vivian and Rose must get every day I would
only  assume if they cannot keep up emails will inevitably get missed so be patient.

Have you the WhatsApp numbers? If not give these a try I find these are the quickest way to get a reply myself.
Vivian Ttian +86 136 9093 8214
Rose Huang +86 188 2485 0694

They have been quoting 20-25 days for X68 frame but I’m assuming depends on frames.
To be honest I have been dealing with Vivian and the response via email and WhatsApp has been fine

Yes today. I will need to wait more 7-10 days. I think they send it not before beginning of may but I dont have stress. They told me they had such a high amount of orders that the painting facility is very far behind. Thats the reason why they stopped orders for some time.

Thanks for the update.
I actually asked about custom paint options on Monday, but was told I they could not change my paint option so UD glossy it is!

What about you—what did you go for in terms of paint?
Is it a full build or just the frame? And if it’s frame-only, what are you planning to build it up with?

I also asked that if the limiting part is the painting if they could send me the raw frame in the case its ok to ride. I dont care at all about the colour.

I was originally told a raw, unprinted frame would take 7–10 days when I first enquired.
But getting it painted here in the UK was estimated at around £500, since the frame would likely still need prepping—almost the cost of the frame itself—so it just didn’t make sense.

I had been looking at a finish called Chromacoat Fireball. I had a frame painted in it a few years back and it looked badass—black, red, and gold. It’s not a colour Tan Tan offers though.

The idea of custom paint only came about after visiting a new local bike shop that opened over the weekend. They had a Trek TT bike in a green-purple flip finish, and it looked stunning. So for an extra $100–150 USD, I thought—why the hell not?

today i sent an email to tan tan, and jessi answered me immediately. great. i requested a no paint frame, i will paint it myself, the price is attractive at 589 instead of 629 dollars. but the tan tan site does not have the automatic payment procedure that the seraph site has. how can i pay on the tan tan site?
he did not specify the production times of the frame or if it was already available in stock.
