The arms may vary depending on the model of frame,
however the assembly process is the same.
Make sure the Press Fit Nuts are facing upwards, and not towards the arms.
Tighten screws until snug, and then a little bit more.
Pro tip: Make sure the tip of the hex driver is fully seated in the screw head
before tightening. This will avoid stripping the screw.
