GT STREET MACHINE Bicycle User Manual


 
While riding you should allow your arms to
rest in a relaxed position on the handlebars.
Do not pull on the handlebars. If the handle-
bars turn in the stem clamping during the ride
stop immediately and tighten the clamping
screw of the handlebars again. If the handle-
bars turn in a stem that is not sufficiently
clamped the handlebars or the stem might be
damaged or deformed. In that case a secure
clamping of the screw can no longer be guar-
anteed, even with the correct tightening tor-
que, and handlebars and stem have to be ex-
changed.
You can make smaller adjustments by moving
the cables in their guides at the frame and the
handlebar, so that there is enough room at all
mobile parts. For this purpose you can move
the cable for the front changer a little bit into
or out of the frame. If this proves not to be
sufficient you will have to have your specialist
dealer shorten the cables or replace them by
longer cables.
Handlebar grips
The grips on the handlebar are susceptible to
wear and tear. Have your grips replaced by
your bike shop once they don't feel comforta-
ble anymore.The grips always need to be atta-
ched firmly to the handlebar.

Adjusting the angle of the handle-
bars
By changing the angle of the handlebars you
can adjust the position of the grip to the
length of your upper body and your arms.
Most riders are comfortable with a 45° angle
so that the grip points diagonally to the front
and up.The more upright the grip position the
lesser is the maximum possible cramp of the
handlebars, since it touches your legs earlier.
In order to change the angle, undo the screw
of the handlebars clamping by some turns.Turn
the handlebars until they are in your favorite
position. Check that the stem clamps the
handlebars exactly in the middle.Tighten the
clamping screw with 10-12 Nm. Check the
correct clamping of the handlebars by moun-
ting your bike and pulling the handlebars. In
doing so they must not turn.
Please take care that the clamping area of the
stem is thoroughly trimmed and does not have
any sharp edges which may lead to a rupture
of the handlebars.
Caution! After you have adjusted the hand-
lebar position you also have to adjust the
length of the brake cables and shifter cables.
The cables have to run smoothly without
any sharp turns and they may not be bent or
stretched beyond their elastic limit when the
handlebar is at maximum cramping.Also avo-
id large arches that could be caught up in
other parts.
Danger! Every time you undo the clamping
connection you'll have to check the screw. It
must not be bent, corroded or damaged. In
addition to this you'll have to check the wel-
ded-on thread nut of the clamping.The thre-
ad must not be damaged and the screw
must turn easily. In case of damage or defor-
mation you have to exchange the clamping
screw immediately.
