They have a good offer right now on ALI,  will be nice to have some feedback from someone who have tested them,  but the 24mm inner 50mm deep and 1159gr at 436€ looks exciting  to me !!

Hello everyone,

Here is my update on the X68 build.

The frame arrived pretty fast and seems to be of good quality.
Unfortunately, the screw for the headset top cap was missing, and my request to TT for a replacement was not answered positively.

The build itself was not difficult.
The only issue was the alignment of the rear brake. I wasn’t able to adjust the rear brake so that the pads were not touching the disc. Finally, after using a 0.25 mm washer, I could adjust the brake caliper in an acceptable way. However, this should not be the standard, especially because you can’t insert the safety pin for the brake assembly screw.

The first rollout was fine so far.
Only the seat post slipped a bit, which I need to monitor during the next rides. Also, the headset play needed to be adjusted twice.

Overall, the first impression and experience aren’t that bad.
But hopefully, I’ll never have a serious issue, because I don’t think TT would take care of it.

I had the same problem with the seatpost on mine. Even tightening the bolt to 6 Nm, the seatpost would still slip. In the end I fixed it by cutting a small shim out of a Coca-Cola can and putting it between the seatpost and the frame. And of course, carbon assembly paste — I’m guessing you’re already using that, right?

I'm Happy with Bucklos as well, i tried different brands from Aliexpress, but bucklos seams  the best option quality/price for me .

Hello everyone,
I’ve been reading your posts since August, and today I finally decided to write for the first time. I went ahead and bought the bike frame from Tan Tan because I was really curious to see how good such an affordable frame could be and whether it was actually worth it or not. Now i can share my feedback with you guys.
As of today, I’ve already done about 1,200 km with the bike, and I can say that I’m very happy with it. My previous bike was a Specialized SL7 Pro, and honestly, I like the TT-X68 much more — it feels faster and lighter than my old SL7.
The only thing that has me a little concerned is cornering. I’ve seen some users complain about how it handles in curves, and I’ve noticed the same. I’m not a great descender, but it’s true that I find it a bit unstable — as if the steering were softer?? I don’t know if it’s because I was used to the stiffness of the Roval Rapide handlebar on the SL7 or if it’s due to the fork, but that’s the only thing that doesn’t fully convince me! ( i have the newer version of the fork, the heavy one).
Maybe it’s not just the handlebar but the whole change of bike setup, since now I’m also riding with a wider rim at lower pressure (4,6 bar front ), and maybe everything adds up. Anyway, I’m thinking about changing the handlebar for a stiffer one without spending too much money. Does anyone have any recommendations? Thanks!
Here’s my current setup:

Frame : TT-X68 camaleon white 56
Wheels:  Ryet 50 F/R  (1430gr not the lightest ones)  with TPU RideNow tubes 24gr each 
Groupset : Sram Force   ( SRAM Force AXS powermeter + cassete force 10-33)
Handlebar: Tantan
Seat : Ryet 3d carbon  from Aliexpress
Pedals:  Bucklos carbon- titanium (220gr) from Aliexpress
