Nice looks rapid.

Nice looking Ostro replica there. Anyway, can you show what type of compression plug given by seller?
Because I've experienced it before, D-shaped steer tube is not working well with normal round compression plug. It tends to loose during ride and for me it's so dangerous.

I find that the expander plugs supplied by any chinese vendor is always shit and you have to replace it.
I just buy a default 50 or 70mm deda and sorted.

hey OP would you mind sharing the taobao link/shop name?

Compression plug doesn't hold any stress while riding. Your handlebar is clamped to the steerer and keeps everything together. Compression plug and top cap function only to set correct tightness for headset.

What. The compression plug is ESSENTIAL at all times. Yes, the top cap is solely for preload, but the plug supports the clamping force of the stem, preventing the carbon steerer tube from being crushed, snapping, and causing an accident.

Does not apply to carbon steerer tubes. Carbon steerer tubes needs the plug.

It's an essential item, my brother. Compression plug help to 'hold' the handlebar in place to the steerer tube. Loose plugs can cause a lot of issues, especially for rider safety.

For the rest will I hijack this topic thread to continue the build of the same replica Factor Ostro VAM. The picture is just for indication of how it looks like, so I know there are no headspacers, etc.

The bottom bracket was not included, but alu axles were. those were 64 gr but I placed those at the wheels section so they are not in the frame weight calculated.

For the rest I have the Lexon Carbon crank and the wheeltop derailleur set. I will go for a 1x setup with a 52 chainring as where I am based it's quite flat.
Probably will go for the Elite Drive wheels or Superteam, I haven't decided yet

Thanks for your feedback. What is the quality of the frame ? (Paint, faced caliper, inside carbon,...)

Always a fan of high level trolling, did we ever get the link to this frame? Owners, can you compare it to other bikes you have ridden?
