3.7 Shifter and Derailleur Adjustment
Front Derailleur Adjustment
Set the chain on the smallest chainring and tighten the tuning bolt on the
lever.
Adjust the L screw on the front derailleur so that it is 1 to 1.5mm away from
the chain. You can loosen the cable first if needed, then tighten it again
later.
Shift to the bigger chainring of the crankset and smallest chainring/cog of
the freewheel or cassette.
Check whether the outer chain guide-plate of the derailleur touches the
chain or if the spacing is too large, adjust the H screw to avoid either
scenario. Maintain a distance of 1 to 1.5mm. If the spacing is too large,
simply adjust the H screw.
Check and adjust the H and L screws until the shifter functions smoothly.
Rear Derailleur Adjustment
Step 1: Make sure the rear derailleur is shifted all the way down to the
smallest cog.
Step 2: Turn your barrel-adjuster all the way tight so that you have room to
adjust it later.
Step 3: Adjust the high limit by rotating the screw marked "H" on your
derailleur so that it lines up with that smallest cog.
Step 4: Tighten the tension in your cable by unscrewing the cable anchor,
pulling the cable tight, and screwing the anchor back on tight.
Step 5: Shift your rear derailleur to the 4th or 5th cog.
Step 6: To adjust the index, turn your barrel-adjuster so that the derailleur
pulley lines up underneath the correct (chosen) cog. With a Shimano rear
derailleur, you want to line up the pulley slightly inboard of the cog. Perform
some practice shifts to make sure it is adjusted properly.
Step 7: Shift your rear derailleur to the largest cog.
Step 8: Adjust the low limit by rotating the screw marked "L" on your
derailleur so that it lines up with the largest cog.
Step 9: Adjust the B-tension screw so that the pulley on the rear derailleur
is as close to the largest cog on the cassette as possible without dragging.
