Operating instructions

Do not clamp the AX-Lightness and engage fork into
a vice to cut it, as this could damage the fork steerer.
Clamp the fork steerer into a suitable device instead,
e.g. into a special bracket (a).
Use a sharp, ne-toothed metal saw (24 teeth) (b) and
cut the fork steerer at low pressure 2 mm below your
marking (c). Make sure to keep the inner steerer tube
free of chips and dust.
Do not blow o the saw chips. Remove the chips with
a damp rag
(d) and dispose of them together with the
rag!
Use a le with ne teeth to gently remove any burrs
from the area of the cut
(e). Insert the le from the
outside to the inside
(f) and not vice versa, otherwise
the bres will fray out.
Seal the cut with two-component adhesive (epoxy
resin), clear varnish or super glue.
Wipe o excess adhesive from the steerer tube side
immediately upon sealing.
Let the adhesive harden before re-installing the AX-
Lightness and engage fork. Make sure all spacers and
the clamping area of the sleeve are free of burrs.
Use AX-Lightness and engage carbon assembly paste
to ensure a reliable t and low torque values on the
steerer tube and the stem itself in the clamping area!
Continue the installation as described in chapters
“Mounting AX-Lightness and engage Ahead-
set®-stems” and “Adjusting the AX-Lightness
and engage Aheadset®-headset”.

If there is no extra long nut delivered with
the road racing fork, use the sleeve nut of
the brake manufacturer for brake instal-
lation. Check that the nut has a minimum
grip of 8 turns!
i
Before installing a brake, be sure to read the
chapter “The brake system” or the manual
of the brake manufacturer. Follow the in-
stallation instructions and pay special at-
tention to the torque values.

Verify that the gaps between bearing cov-
er and head tube as well as between fork
crown and lower bearing cup race are even-
ly parallel. If they are not, the bearings pos-
sibly run rough.
