Front Derailleur
Shift both shifters to the smallest number indicated and place
the chain on the corresponding cog and chainwheel. Discon-
nect 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 barrel adjusters to fine tune
each transition. The barrel adjuster 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 proper-
ly. Overlooking proper adjustments may cause
irreparable damage to the bicycle and/or bodily
injury. Never move the shifter while pedaling
backward, nor pedal backwards after having
moved the shifter. This could jam the chain
and cause serious damage to the bicycle
and/or rider.
