Step 8: Set the desired seat height. Open the quick release lever by hinging it
open fully. Ensure the seatpost clamp opening is aligned with the notch at the
front of the seat tube. Adjust the seatpost up or down to a comfortable height,
while ensuring the seatpost is inserted into the frame past the minimum
insertion point.
If needed, use the thumb nut to add tension to
the clamp so there is some resistance when the
lever is in line with the clamp bolt, but do not
overtighten. Close the quick release lever to
secure the seatpost and check that it cannot
move.
