3. While hand-turning the cranks, use the
shifter to carefully shift the chain onto the
outside chainring.
4. With the shifter, position the outer chain
guide of the front derailleur approximately 0.5
mm from the chain.
5. Re-tighten the high gear adjusting screw until
it meets resistance. If you have turned the
screw too far, the front derailleur will move
toward the small chainring.
Check your adjustments; go through the
various gear combinations. Make sure the
chain does not fall off when you shift, and the
derailleur cage does not rub on any part of the
crankset.
To adjust the middle gear position of the front
derailleur, with three chainrings
1. Shift the chain onto the largest front
chainring and the smallest rear cog.
2. Rotate the cable tension barrel-adjuster (on the
downtube, or on the lever) counter-clockwise
increasing cable tension to align the inner
derailleur cage until it just touches the chain.
Go through the various gear combinations to
ensure the chain smoothly lines up with all the
chainrings.
Note: some front shifters have a ‘tab’ feature. By slightly downshifting
the lever, the derailleur should move in slightly, and should no longer be
touching the chain.
