Hey,
in most posts about new builds there is talk about facing the BB or brake tabs because the Chinese Frames might not be perfect. There is also a lot of talk about it in Hambini and other YT videos.
I know there are extremely expensive tools to do that, but in my experience not even all the bike shops have those.
So the question is, has anyone found a Ali solution this? Or maybe a 3d printed file guide or something similar?
