I’ve been a silent observer on various forums discussing different frame options, and eventually decided on the TT-X68. Unfortunately, I now regret that choice—here’s why.
I placed my order on March 13th, selecting the matte black frame with a glossy black Seraph logo. I was quoted a lead time of 15–20 days. Communication was handled via WhatsApp with Rose.
Aware of potential production delays from others’ experiences, I reached out on April 9th and was told to wait another 7–10 days due to a backlog. I followed up again on April 23rd, only to discover—after several unread messages and eventually emailing Tantan—that Rose had changed her number. I reconnected with her on April 30th and was informed my frame would ship on May 6th, after the Labor Day holiday.
Throughout the process, I remained polite and patient, knowing delays can happen and because I wasn’t in urgent need—I have other bikes to ride. However, on May 6th I received no response. On May 8th, Rose finally replied, saying the frame was ready and she’d send pictures for my review. That’s when I was told the 100/400 handlebar size I initially ordered wasn’t reserved for me. I agreed to wait another week for it to be produced.
Upon reviewing the frame photos and video, I noticed a defect: the middle line of the letter "E" in the logo was missing. I raised this with Rose immediately. On May 10th, she responded that the package had already shipped and claimed the missing line was just hidden under a sticker film that I could peel off. The package arrived on May 23rd—71 days after my order, far from the promised 15–20 days.
Unfortunately, there was no film to remove. Instead, I scratched the paint trying to find it, leaving the logo looking like "SCRAP(H)." Rose’s solution was to send me a new logo to stick on, but that’s not viable—the original logo sticker is embedded deeper in the frame and paint and varnish layers around the logo are rising around the logo. I’m not willing to experiment with DIY fixes on a brand-new frame.
Her latest offer is a $30 refund and a replacement logo, or I can return the frame at my own cost—something I won’t accept. She also mentioned they didn’t charge me for the logo in the first place, which I find irrelevant. I’ve proposed two fair solutions: either they cover the cost of local repainting or handle return shipping.
We’ll see how the conversation continues tomorrow when she’s online again.

I'll be honest, the way you started this post, I thought you had a catastrophic frame or fork failure.
I don't want to dismiss your feelings; they are valid, you paid for the service, and it didn't deliver as per the requirements.
However, in my humble opinion, you are overreacting.
I'm just here praying that the frame and fork I'll receive won't fail on me and cause a serious injury.
Let's be realistic and adjust our expectations here. It's a Chinese OEM factory that most likely outsources the production of this frame, and they operate via WhatsApp or Email for sales. These things happen.
If you have buyer protection via PayPal you can escalate things.

Yet I would not be surprised if OEM brands started artificially inflating their prices if more and more consumers jumped on the bandwagon. Yishun/LC immediately did this when I uploaded my review of the R086-D frame. Double edged sword.

Even TanTan/Seraph has increased the prices slightly for their TT-X68 frame and full builds. Their complete build was USD 2399, now it is USD 2539. The painted frames were USD 719, now some of them are USD 775(https://www.seraphbikes.com/Special-Red-Paint-Superlight-Disc-Road-Bike-Frame-TT-X68-BSA-Bottom-Bracket-Max-Tire-70032C-With-Integrated-Handlebar-p6397145.html), while some others are USD 729.

I can imagine the prices spiking once someone like you, Patrick, makes a video on them.
