Step 3
The steerer must sit 3mm below the top of the stem or spacer, depending on your configuration.
When using a spacer on top of the stem, the steerer must sit 3 mm below the top of the spacer (shown).
When not using a spacer on top of the stem, the steerer must sit 3 mm below the top of the stem (not shown).
Step 4
Tighten the two steerer clamp bolts clockwise by hand just enough to maintain the correct stem position.
