Handlebars - Dynacraft SINGLE SPEED Owner's Manual

HANDLEBARS

Most of our bikes are equipped with a "quill" stem (figure X). To assemble the handlebars remove the
protective cap from the wedge end of the stem bolt and loosen the bolt using the 6 mm Allen key. Some
models may use a 13 mm hexagonal bolt instead of an Allen key bolt. Place the handlebar stem into the top
of the steer tube which is the top end of the fork that has been inserted into the head tube at the factory,
ensuring that all cables are free of tangles. Tighten the stem bolt observing the Minimum Insertion Mark
and checking that the forks and the handlebars are facing forward. After the stem bolt is tested tight (see
Important Note below), adjust handlebars to correct position. Loosen the 6 mm Handlebar Binder Bolt (See
Figure X) and rotate the handlebar forward so the brake levers are at a 45 degree angle below the handlebar.
Retighten the Binder Bolt to ensure the handlebar does not rotate in the stem. After the handlebar stem has
been fitted into the steer tube that is the top end of the fork and the two pieces made firm within the head
tube the action of a stem bolt upon the wedge nut binds with the inside of the steer tube to form a solid
steering column.

Important Note: Test the security of the handlebar stem within the steer tube of the front fork by
clamping the front wheel between your knees and trying to move the handlebar and/or stem from side
to side. The handlebar should not move independent from the front wheel when applying pressure.

WARNING
A loose stem bolt can cause a loss of steering control
and result in serious injury or death. The stem must be
tight enough for the wedge nut to bite into the inner
surface of the steer tube.
