I’m putting together the same frame and wanted to see if this frame has a hydraulic hose clamp inside the down tube under the bottle cage. You don’t show that part but I still watched your video 2x. Great production!
It's muc off silicon shine, to protect and make the bike very shine. It also make the mud not stick to the bike on mountain bike, you can use WD40 it also work. spray on the cloth and applied with it to avoid pollution on your disk brake
Torque is mostly for customer for them to not break bolds or to be tight enough. I only use torque when I clamp the stem to a carbon bar. Otherwise I’m so used to tight just enough and not too much 😉
On the top ? You can put as many as you want it’s just not gonna be very pretty and can be hurtful if you crash on it, you can also cut your fork pivot to the right size
