PART 1
5.A - Service Intervals
Section 5. Service
GT Bicycle Owner’s Manual
• Lift the front wheel off the ground and swing
it from side to side. Feel smooth? If you feel
any binding or roughness in the steering,
you may have a tight headset. Have your
dealer check it.
• Grab one pedal and rock it toward and away
from the centerline of the bike; then do the
same with the other pedal. Anything feel
loose? If so, have your dealer check it.
• Take a look at the brake pads. Are they worn
or not hitting the wheel rim squarely? Time
to have the dealer adjust or replace them.
• Carefully check the control cables and cable
housings. Any rust? Kinks? Fraying? If so,
have your dealer replace them.
• Squeeze each adjoining pair of spokes on
either side of each wheel between your
thumb and index finger. Do they all feel
about the same? If any feel loose, have your
dealer check the wheel for tension and
trueness.
• Check the tires for excess wear, cuts or
bruises. Have your dealer replace them if
necessary.
• Check the wheel rims for excess wear, dings,
dents and scratches. Consult your dealer if
you see any rim damage.
• Check to make sure that all parts and
accessories are still secure, and tighten any
that are not.
• Check the frame, particularly in the area
around all tube joints; the handlebars; the
stem; and the seatpost for any deep
scratches, cracks or discoloration. These are
signs of stress-caused fatigue and indicate
that a part is at the end of its useful life and
needs to be replaced. See also Appendix C.

SAFETY.
5. Disc brakes require a different set of
inspection steps. Check for these issues
before every ride::
• Pads rubbing on rotors.
• Worn out pads (which can lead to
over-extended pistons).
• Pistons that are stuck and/or won’t retract
fully.
• Disc rotors that are bent and need
straightening by the dealer.
