Im considering the SC-R55D. What groupset did you go with? I'd like to go mechanical but since its basically a Tavelo Arow not sure if its supported. Also does it have the same D shaped steerer?

sorry I can't answer your question but following cause if I build, I'll build with either 30mm or DUB crank.

I got some pictures from the preproduction models. Weight should remain the same for production.

Post other photo, I don't understand where that hole is, in mine I don't found

Maybe you can go and have a look at Hanbini's post. Z3/Z7/Z11 is just Hanbini's definition of frame quality. This definition is not given by us. It is a definition given by Hanbini based on his experience after talking and discussing with our supervisor Gavin (fifteen years of experience in carbon fiber frame production and sales) and boss Johny (20 years of experience in frame design and production) at Eurobike 2024.
Hanbini did not say that all our LC frames are Z3 standard. We have also told customers that our frames meet most of his descriptions of Z3 quality: high modulus carbon fiber material, 3D latex inner mold as support technology, testing beyond the conventional EN4210 standard, strict quality management, and good after-sales service. But we never shy away from the fact that our packaging is simple but safe, and there is no paper technical manual.
We had no business dealings with Hanbini. At that time, he needed a good product to make a video, and our frame just happened to appear at that time. It was a wonderful encounter. We just provided him with a frame for free.
Not all relationships need to be supported by money. Hanbini values ​​his reputation more.
