Operation Manual

• Carbon steerer tubes are usually fabrica-
ted in a highly precise way. For this rea-
son, the stem normally fits snugly on the
fork. Do not mount any stems which have
play when put on the steerer tube.
• Do not grease the steerer tube in the clam
-
ping area of the stem!
• If you have strictly followed the above, you
will not need high torques for the clamping
bolts. With regard to the necessary tor-
ques, see chapter 29. “Recommended tor-
ques for bolted connections”
. Approach
these torques by means of a torque wrench
in 0.5 Nm steps.
If the torques for two components to be
combined differ, make it a rule to stick to
the lower torque.
• Test the secure seat of the stem to the fork,
by trying to turn the handlebar against the
front wheel.

• If there is no particularly long nut delivered
together with the fork, use the sleeve nut of
the brake manufacturer included for the
brake mounting. Check that the nut has a
minimum grip of 8 turns!
Never exceed the torque prescribed
by the stem manufacturer and the
maximum torque of the fork (chapter 29.
“Recommended torques for bolted connec
-
tions”)! Retighten all bolts after the first 100
- 300 km to the prescribed torque and then
every 2,000 km.
