Open the QR Lever to 90
degrees and slowly rotate the
clock nut until it stops against
the handlebar stem lower.
Rotate so that one of the holes
in the clock nut aligns with
the hole in the stem lower to
allow the securing bolt to be
refitted.
The QR should have roughly
120 degrees of free play
before it beings to engage.
The closing resistance should
act over the remaining 60
degrees of movement till it is
firmly shut in the correct
location.
If it is too loose, rotate the
clock-nut clockwise till the
next hole aligns with the hole
in the stem lower and recheck
Conversely if it is too tight
rotate the clock-nut
anticlockwise to the next hole
and recheck.
