Intended use
The Sixpack Millenium ICR stem/Sixpack ICR system is compatible with all
Acros ZS56 ICR headsets. In addition, the Sixpack ICR System can also be
retrotted to Acros 52/52 ICR angle headsets and Acros 52/60 ICR angle head
sets with an aftermarket compression ring (Acros item no. 11.52.106R2AM).
Compatibility
Sixpack components are designed for the following categories according to
ASTM F2043:
• MILLENIUM and EJ Stem: Category 5
Category 5: Extreme use (downhill, freeride, dirt)
Category 5 includes the use of bikes and their components under the
conditions of categories 1, 2, 3 and 4 as well as in demanding, heavily blocked
and extremely steep terrain, which can only be mastered by technically
experienced and very well trained riders. In this category, big jumps are
to be expected as well as intensive use in bike parks or on downhill tracks.
With these bikes it is essential to ensure that after each ride an intensive
check for possible damage is carried out. Predamages can lead to failure
even if further stresses are signicantly lower. A regular replacement of
safetyrelevant components should also be considered. Wearing appropriate
protective gear is absolutely essential. Long travel fullsuspension bikes but
also dirt bikes characterize this category.

The statutory warranty applies to all components. If damage occurs
outside the warranty, contact us and we try to nd an individual
solution.

Guarantee / Crash Replacement
• The tightening torque of the stem must not be exceeded.
• Additionally, check the handlebar manufacturer's instructions for
specic provisions. In particular, the tightening torque may be
restricted by the handlebar manufacturer.
• The assembly sequence must be observed. The clamping points
labeled "NO GAP" must be tightened rst.
• Do not use grease or other lubricants to mount the stem.
DANGER
Danger due to incorrectly mounted stem!

Disassemble the Acros ICR
Note: Measure from the highest point of the Acros ICR Topcap to
the end of the steerer tube. The Sixpack ICR system requires at least
47mm free shaft length. With the minimum shaft length, you can no
longer use spacers.
Min. 47mm

Disconnect all lines and cables from attachment points such as
brake and shift levers. If necessary, disconnect the cable to your
dropper seatpost or the power supply of an ebike display/control
unit.
Loosen the handlebar clamp bolts of the stem and remove the
handlebar.
Loosen the headset adjustment bolt.
Loosen steerer tube clamp bolts of the stem and pull the stem and

Route the cables through the cutouts in the lower ICR cover. Use
the same arrangement as with the previously installed Acros ICR
system. Make sure that the lines are not crossed or twisted through
the cover. Assemble the lower Sixpack ICR cover by inserting the
pins into the holes provided in the compressionring.
Do not cross or twist
the cables

Slide the according number of spacers onto the steerer tube to
adjust your desired handlebar height.
Seite 20
Note: The spacers are symmetrically. You can adjust the
handlebar height of your bike with the help of the spacers
even when the Sixpack ICR system is assembled.

4Slide the top cover of the Sixpack ICR system with the pin facing
down onto the steerer tube to the top of the spacers.
Route the cables through the opening of the top cover and make
sure that the cables are not crossed or twisted through the top
cover.

5The seal of the Sixpack ICR system can accommodate up to four
lines or cables. The four openings for lines or cables are preper
forated on the back of the seal. The two inner openings are for shift
cable housings, the two outer openings are for brake lines. Choose
the assignment of the opening according to the arrangement of the
brake and shift levers on your bike. Do not cross the cables or lines
through the seal.

6Pierce the appropriate holes in the gasket with the lines. Slide the
ICR seal toward the steerer while using one hand to hold the cables
and hoses under tension.
Note: Keep the cables and lines under tension so that you don‘t push
them back into the frame to avoid the cables to be too short.

7Slide the stem onto the steerer tube. Make sure that the ICR seal is
placed within the recess of the top cover. In the correct position, the
frontside of the seal is ush with the frontside of the top cover of
the Sixpack ICR system.

2Add or remove desired number of spacers. Please note that the
steerer must be long enough if you want to add spacers. The top of
the stem should be around 3mm above the steerer tube.
If you want to remove spacers, please note that you have to add the
according number of round standard spacers above the stem to
headset adjustability.
