Commencal FCB - Derailleur; Cable Tension

DERAILLEUR POSITION SET UP CABLE TENSION
The limit screws prevent your
chain from exceeding the limits
of the cassette. You have one
screw controlling the higher
limit (H) and one screw for the
lower limit (L). The higher limit
corresponds to the smallest
cassette ring while the lower
limit corresponds to the big-
gest cassette ring.
Adjust so that you achieve
the correct limitation without
compromising gear range.
To ensure the correct setting
you must be sure that:
- When your chain is on the
biggest gear, align the center of
the upper guide pulley
with the outboard edge of the
smallest cog.
- When your chain is on the
lowest gear, the derailleur
pulley should align with the
largest cassette ring.
Once your limit screws are set, you have to
adjust the cable tensionner. Try shifting through
the gears:
-If you have difculty shifting from smaller to
bigger rings then loosen gradually (turn anti-
clockwise) the cable tensionner to tighten the
cable.
-If you have difculty shifting from bigger to
smaller rings then tighten gradually (turn
clockwise) the cable tensionner to untighten the
cable.
Make sure
your derailleur
hanger is not
bent.
