Have heard BB shell bore not perfectly round but haven't heard threaded insert coming loose. For me manufacturers going back to threaded BBs (BSA, T47) is a very welcome news.

Staying with anecdotal observations. I never had issues with pressfit and if so I would have either bought a bb with a threaded inner shell - or simply glued in the shells with Loctite 683*.
From an engineering perspective the advantages of pressfit overweight the downsides. The biggest downside of pressfit is it's reputation because people are unaware of the proper installation process. Maybe I have to correct myself by saying the biggest downside of pf is therefore the higher chance of improper installation as opposed to threaded bbs.
This is also covered by "peak torque". I just couldn't find the video in which he said that. But while searching for the vid I came across another video which explains this topic: https://youtu.be/33IWHSGl1nU?si=an7GdPbuU_WQ3gx-

Btw. I asked them a few questions:
is it possible to provide an own logo for the frame?
---Sorry, no
do you also offer the Graro fork without bolts?
---Sorry, no
how big is the setback/offset of the seatpost?
---15mm
do you offer a seatpost with less seatback?
---Sorry, no
is it possible to order the frame in pearl white and fork in chameleon?
---Yes.

* "wtf?! You would end up having worn bearings and therefore a frame to be dumped." Actually no. I just use a good quality bb with replaceable bearings.

Anybody get response from David, I wrote him a mail last week, no answer...?!

I wrote him last week as well and still waiting for a reply. I would like to get more information about the frame, as pricing, release date...
What is your opinion about Spcycle as brand at all? Had anybody already gained some experience with it?
For me it would be the first Chinese frame 

UPS
Yeah 35mm should fit without any problems

Cool. Thanks. I'll order one to see the quality then and do a simple build with a 105 I got laying around

I'm currently driving a 30mm Vittoria Corsa Next and there's not a lot of space. 35mm shouldn't be a problem at all

Sorry your message was a bit confusing
