4 Adjustments
Adjust the Front Derailleur
WARNING!
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, nor pedal
backwards after having moved the shifter. This could jam the
chain and cause serious damage to the bicycle and/or rider.
❶ Shift both shifters to the smallest number indicated and
place the chain on the corresponding cog and chainwheel.
❷ Disconnect the front derailleur cable from the cable anchor
bolt. Figure 4.25
❸ Check the position of the front derailleur; it should be
parallel with the outer chainwheel and clear the largest
chainwheel by 1-3 mm when fully engaged.
❹ 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.
❺ Reconnect the cable, pull any slack out and tighten the cable
anchor bolt securely.
❻ 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.
40
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.
❼ 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.
