If you are unsure of the safety of your
handlebar system, do not attempt to
ride your bike. Never ride your bicycle
with the stem raised above the
minimum insertion mark as this may
cause loss of control resulting in
personal injury or death. A minimum
of 2 3/4 inches (70mm) of the stem
must always remain in the frame.
When adjusting the seatpost ensure
the minimum insertion mark remains
inside the frame. A minimum of 2 1/2
inches (64mm) of seatpost must
remain in the frame. Riding with the
seat raised above this height may
cause loss of control resulting in
personal injury or damage to your
bike.

ADJUSTMENT OF HANDLEBAR AND SEAT
HANDLEBAR STEM ADJUSTMENT:
Your handlebar’s primary function is to steer and control your bicycle, therefore proper installation,
adjustment and maintenance are crucial for your enjoyment and safety.
To change the handlebar height, loosen the stem expander bolt two to three turns, then tap the top of the stem
handlebars to the desired height, and retighten very tightly (175-260 lb.lin or 19.8-29.4Nm).
MAKE SURE THE MINIMUM INSERTION LINE IS NOT SHOWING ABOVE THE HEADSET.
Some bikes are equipped with a stem that has an adjustable rise, or
angle. These bikes require that you tighten the angle adjusting bolt to
150-170 lb.lin (17-20.3 Nm) after first making sure the teeth are correctly
engaged with the corresponding teeth entered between the teeth of the
mating part.
Note: Some bikes are equipped with
handlebar stems that are not adjustable in
height.
Test the security of the handlebars in the
stem and the stem in the frame, by
attempting to twist the handlebars in the
stem and by attempting to turn them from side to side with the front wheel
locked between your knees (Fig.5). Make sure there are no cables stretched or
pinched by rotating the handlebars.
SEAT ADJUSTMENT:
Your seat and seatpost are the primary means of support for the rider.
Proper adjustment is important for your comfort and pedaling efficiency.
Ensure your seat and seatpost are securely tightened in a comfortable
position for your riding style.
Ensure that the seat is secure by attempting to turn the seat and seatpost
in the frame. Grabbing the saddle, attempt to move the front of the saddle
up and down and side to side. If it rotates, is loose, or moves up and
down, tighten the quick release and repeat the test until there is no
movement.
