Front Derailleur
(Fig. 3.44) Shift both shifters to the smallest number indicated and place the chain
on the corresponding cog and chainwheel. Disconnect the front derailleur cable from
the cable anchor bolt. Check the position of the front derailleur; it should be parallel
with the outer chainwheel and clear the largest chainwheel by 1-3mm when fully
engaged. With the chain on the smallest chainwheel in front and the largest cog in back,
adjust the
Low limit screw so the chain is centered in the front derailleur cage. Reconnect
the cable, pull any slack out, and tighten the anchor bolt securely. Shift the front shifter
to the largest chainwheel. If the chain does not go onto the largest chainwheel, turn the
high limit screw in 1/4 turn increments counter-clockwise until the chain engages the
largest chainwheel. If the chain falls off the largest chainwheel, and into the pedals, you
will need to turn the High limit screw in 1/4 turn increments clockwise until the chain
no longer falls off. Shift through every gear, using the adjustment barrels to fine tune
each transition. The adjustment barrel for the front derailleur is located on the front
shifter where the cable comes out of the shifter. Clockwise will loosen the cable tension
and direct the chain closer to the frame while counter-clockwise will tighten the cable
tension and direct the chain away from the frame.
Do not ride a bicycle that is not shifting properly. Overlooking proper
adjustments may cause irreparable damage to the bicycle and/or bodily
injury. Never move the shifter while pedaling standing up, or under heavy
load, or pedal backwards after having moved the shifter. This could jam
the chain and cause serious damage to the bicycle and/or rider.
