From the back of the guide, use a 4mm allen key to
remove the rearward skid bold from the lower portion
(FIG. C). Swing the lower portion of the guide down
(FIG. D).
3
Install the crankset and chain and reinstall the upper
guide (FIG. D). Tighten the upper guide bolt to 1.2-
1.3 Nm. There should be roughly 3mm of space
between the chain and the ceiling of the upper guide.
4
Swing the lower portion of the guide closed and
reinstall the rearward skid bolt from the back of the
guide (FIG. G). Tighten to 3.5-4 Nm. If you encounter
trouble with the alignment of the rearward skid bolt,
double check that the pocket of the lower portion
of the guide is free of dirt and debris and that the
backplate is able to fully seat within it. A slight tap
with the palm may be required for the backplate to
fully seat.
Check that all fasteners have been appropriately
tightened and that there is no unwanted rubbing
or contact anywhere in the assembly (FIG. H). On
full-suspension installations, remove the air or coil
from the shock and fully cycle the suspension to be
certain. Check the functionality of the of the guide in a
safe environment.
6
7
Check that the alignment of the guide is correct.
The chain should be centered in the upper guide
in the middle range of the cassette (FIG. F). There
should be little or no contact between the chain and
upper guide while in the smallest or largest cogs of
the cassette. Refine this spacing using the included
ISCG spacers if necessary.*
*This will require reversal of the installation steps thus far and
restarting at step one.
