Adjusting The Derailleur - Schwinn HYBRID BICYCLE Owner's Manual

ADJUSTING THE DERAILLEUR

WARNING!
Ensure all bolts are secured tightly and the chain does not fall
off in either direction.
Although the front and rear derailleur is initially adjusted at the
factory, you will need to inspect and re-adjust both before riding
the bicycle.
Adjust the Rear Derailleur
❶ Begin by shifting the rear shifter to largest number indicated
and place the chain on the smallest sprocket. Figure 4.23
❷ Adjust the high limit screw so the guide pulley and the
smallest sprocket are lined up vertically. Figure 4.24
❸ Shift through the gears, making sure each gear achieved is
done quietly and without hesitation. If necessary, use the
barrel adjuster to fine-tune each gear by turning it the
direction you want the chain to go. For example, turning
clockwise will loosen the cable tension and move the chain
away from the wheel, while turning counter-clockwise will
tighten cable tension and direct the chain towards the
wheel.
❹ Shift the rear shifter to gear one and place the chain on the
largest cog.
❺ Adjust the low limit screw in quarter turn increments until
the guide pulley and the largest cog are aligned vertically.
❻ Again, shift through each gear several times, checking that
each gear is achieved smoothly. It may take several attempts
before the rear derailleur and cable is adjusted properly.
