2 INSTALLING THE FRONT ISOSPEED DECOUPLER
9.
Place one hand on the opposite side of the head
tube (9a) and with the other, insert the torque key
into the nut and apply pressure with both hands
until the nut seats into the head tube (9b). Then
turn clockwise, with firm pressure (9c). This will
draw the screw inside the head tube towards the
nut.
Turn until snug, do not fully tighten.

NOTE
The decoupler should move
freely after installation. If it
does not, loosen and reinstall,
clean the connections and
apply grease.

Lower the pre-load spacer into the decoupler
so that the label ‘BEARING’ is on the top and
‘SPRING’ is pointed down. Also note that there
are flat sides; these line up with the screws on
either side of the decoupler.
