Stem Superbox DCR
5.1 Assembly procedure
The assembly procedure is as follows:
1 • Replace the original headset topcover mounted
on the bicycle with the one included with the
Superbox. Two covers are supplied, one compatible
with 46mm head tubes (13) and one 56 mm for
DCR system (12). Use the black compression ring
for DCR 45°×45° bearing or the grey version for
36°×45° bearing (14). The black compression ring is
included with the DCR headset.
2 • In case of internal cable routing, first insert
the cables inside the cover and secure it with the
M3×20 mm screw included.
3 • Insert the aero spacers in the fork steerer above
the headset topcover respecting the following
indications:
– The 10 mm (10) and 20 mm (11) spacers are
optional and allow you to adjustthe stem at the
desired height.
– The S-DCR cover (8), if used (see paragraph 4.
Cable routings), must be positioned directly under
the stem and fixed with the screw (9).
– The distance between the upper edge of the
stem and the upper edge of the fork steerer must
necessarily be 3
≈
4 mm.
– It is allowed to use a standard 5 mm spacer
HDALADCR05X above the stem.
If necessary, cut the fork steerer according to the
manufacturer’s instructions and make sure there
are no notches and / or irregularities on the cut
surface. It is recommended that this operation
be done by an official Deda Elementi dealer or a
qualified bicycle technician.
4 • Install the handlebar on the stem, starting
secure it to the faceplate so that the handlebar can
still rotate. At this point, insert the stem into the
fork steerer.
5 • Insert the expander (not included) into the fork
steerer and secure it respecting the tightening
torque indicated by the manufacturer. WARNING:
Make sure that the expander you use has a length
greater than the height of the stem collar so that
both rear screws of the stem tighten on a portion
of the fork steerer completely occupied by the
expander itself.
6 • 6 Install the dedicated aero cap (2) and tighten
the compression screw to preload the bearings
and reset the axial play in the headset.
WARNING: Overtightening can damage the ball
bearings that could get stuck under stress. Follow
carefully the tightening torque recommended by
the headset manufacturer.
7 • Make sure the stem is aligned in the correct
position. Tighten the two rear stem screws
alternately, turning 1/2 turn at a time, until a
minimum torque of 4Nm is reached. If the stem
is not tight enough, increase the torque up to a
maximum of 5 Nm. Please check the stem, which
should not rotate on the fork steerer. WARNING:
Always use a calibrated torque wrench to tighten
the screws. Use the minimum tightening torque
required to ensure that the stem does not rotate
on the fork steerer (Max. 5 Nm). An unnecessarily
high torque generates a dangerous state of
stress on the fork steerer that can create cracks
and/or break without notice and cause serious
accidents to the user.
8 • Rotate the handlebar to the desired position
and tighten alternatively the faceplate upper and
lower screw, 1/2 rev. each time, up to the reaching of
the tightening torque of 5 Nm.
Check the symmetry and equality of all the
distances between faceplate and stem body, if
necessary. The distance between the faceplate
and the attachment body must be the same on the
upper and lower part.
