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
retrotted to Acros 52/52 ICR angle headsets and Acros 52/60 ICR angle head
sets with an aftermarket compression ring (Acros item no. 11.52.106R2AM).
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. Predamages can lead to failure
even if further stresses are signicantly lower. A regular replacement of
safetyrelevant components should also be considered. Wearing appropriate
protective gear is absolutely essential. Long travel fullsuspension bikes but
also dirt bikes characterize this category.
