Longteng also updated their LTK266 model with T47 and UDH. Basically it's the same frame but for me (EU) it's around 400$ more than Longteng's offering. Also Alisa from Longteng assured me, that they're using T1000 and T1100 for 2025 LTK266, Tideace says it's T800 + T1000. Interesting. I will ask Alisa about that, to see what she has to say. Is it possible for them to use different carbon material for one frame? Could be. Few of the sellers even suggested me, that they could use T800 instead of T700 for a little bit extra price (for the same mold). Below photos of the new LTK266 (well, it's the same frame).
Alisa never said some BS nonsense about their frames and how amazing they are and please buy. She was always honest and open about what they do, who they worked with (obviously, to some extend) even if the answer wasn't in their favor. She seems very professional unlike some other sellers. Also communication with Alisa is amazing, she responds pretty fast, can't complain.
