Vinci Handlebar and Stem
1. Replacement of the original headset topcap
with the Vinci topcap (included). Two topcaps are
supplied: one compatible with headtubed of 46
mm (16) and one of 56 mm (14). With this last one
also the compression ring has to be used with
the one for the 36°×45° bearing (17) or 45°×45°
bearing(*).
* Included with DEDA DCR headset
REMARK: The bikes with external cable routing
and 1”1/4 are compatible with Vinci. In this case
assembly the stem without the alloy sleeve (8)
and use the topcover 52mm(*).
2. Install spacers on the fork steerer above
the top cover following below instructions:
• It is mandatory to use the 8 mm first spacer
(10) and it must be installed directly under the
handlebar stem.
• 5 mm (11), 10 mm (12) and 20 mm (13) Aero
spacers are optional. They can be used to
adjust the stack height according to the desired
handlebar position.
• The gap between the top of the handlebar stem
and the top of the fork steerer must be within a
range of 3 to 4 mm. If necessary, cut fork steerer
according to manufacturer’s instructions. Ensure
there are no sharp burrs on the steerer tube.
WARNING: Do not put spacers above the stem.
The lower edge of the stem, which applies
pressure on an area not supported by the
expander, will cause fork steerer ovalization and
dangerous cuts and serious risks for your safety.
3. Install the handlebar (1) on the stem tightening
the upper screws of the face-plate up to gap,
loosening the lower screws in order to allow the
stem to rotate. At this point, insert the stem into
the fork tube with lateral fixing screws loosened
in order to allow the stem to slide along the tube.
WARNING: In case of assembling of full internal
cables routing, please carry out the the cables
routing before proceeding to the next step.
REMARK: use the adapter (8) for forks 1”1/8
4. Install the expander (not included) in the fork
steerer until it stops, and tighten the expansion
bolt at maximum of 3 Nm.
WARNING: Make sure that the expander has
enough length to ensure the stem rear screws
seat on the expander portion of the fork steerer.
This will reduce the risk of fork steerer notching
while tightening the stem rear bolts.
5. Install the Aero top cap (7) and tighten the
compression bolt to preload theheadset bearings
and adjust the headset play.
WARNING: Overtightening can damage the ball
bearings that could get stuck under stress.
Follow carefully the tightening torque
recommended for the operation and
maintenance manual of the headset you use.
6. Ensure handlebar is aligned straight in relation
to the direction of travel. Tighten the two rear
stem screws alternately, turning 1⁄2 turn at a time,
until a minimum torque of 4Nm is reached. If the
handlebar stem is not tight enough, increase the
torque up to a maximum of 5 Nm. Please check
the handlebar stem, which should not rotate on
the fork steerer.
WARNING: Always use a calibrated torque
wrench to tighten the bolts. Use the minimum
stem bolts tightening torque required to ensure
that the handlebar stem does not rotate on the
fork steerer (Max. 5 Nm). An unnecessarily high
torque generates a dangerous state of radial
compression on the fork steerer which can cracks
and/or break without notice.
7. Rotate the handlebar to the desired position
and tighten alternatively the faceplate lower
screw, 1⁄2 rev. each time, up to the reaching of the
locking couple of 5 Nm.
