Laser pointer calibra�on schema�cs
Direc�on and extent of ini�al error will vary
Masking tape
No BB spacer
Install the laser pointer into the BB laser holder
with one adjustment grub screw aligned horizontally as
shown in detail A and secure in place with the top set
screw.
Posion and secure the head tube carriage as far away
from the BB carriage as possible. Apply some masking tape
to the head tube carriage as shown.
(Fig. 1) - Turn the laser on and posion the laser holder
so that the laser dot strikes the masking tape. Clamp the
laser holder in place with the nut and mark a vercal line
through the centre of the dot (A). Turn the laser o.
(Fig. 2) - Without removing the laser from the holder, or
making any adjustment to the grub screws; re-orientate
the BB laser holder as shown. Switch the laser on and
adjust the rotaon of the holder so that the laser strikes
the masking tape at roughly the same elevaon as the rst
mark.
(Fig. 3) - Mark another vercal line where the laser strikes
the tape (B). It is important that the head tube carriage has
not moved since making the rst mark.
(Fig. 4) - Measure the distance between the marks and
make another vercal mark half way between (C).
(Fig. 5) - Adjust the horizontal grub screw on the pointer so
that the laser strikes the central mark.
Return the BB laser holder to its original orientaon and
repeat the process so that you are sased that the laser
strikes in the same place with the holder in both orienta-
ons.
This ESSENTIAL process veries that
the laser is projecng perpendicular
to the BB axis.

This ESSENTIAL process validates that the laser

Ensure the laser holder is securely
clamped with a consistent force each
me a measurement is taken.
