Derailleur; Rear Derailleur - Dynacraft SINGLE SPEED Owner's Manual

DERAILLEUR

Although the front and rear derailleur are initially adjusted at the
factory, you will need to inspect and possibly readjust both before
riding the bicycle.

REAR DERAILLEUR

Begin by shifting the rear shifter to largest number indicated,
disconnect the cable from the rear derailleur cable anchor bolt,
and place the chain on the smallest sprocket. Adjust the High limit
screw so the guide pulley and the smallest sprocket are lined up
vertically. Reconnect the cable, pull out any slack, and retighten
the anchor bolt securely. Shift through the gears, making sure each
gear achieved is done quietly and without hesitation. Shift the rear
shifter to gear one and place the chain on the largest cog. Adjust the
Low limit screw in quarter turn increments until the guide pulley and
the largest cog are aligned vertically. 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. (See top drawing.)
NOTE: Some bicycles may be equipped with a rear derailleur
mechanism that works in reverse to the directions above.
Some derailleurs may have an adjusting barrel (see bottom drawing).
Use the adjusting barrel to fine tune the adjustment of the chain
location. Turning the adjusting barrel clockwise will move the derail-
leur inboard - towards the wheel, while turning it counterclockwise
will direct the chain outboard - away from the wheel.
WARNING
Ensure all bolts are secured tightly and the chain
does not fall off in either direction. A loose chain can
cause a lose of control and serious injury.
