Safety Quick start Riding Maintenance Resources
Brakes
Check the brake pads for wear
• Replace disc brake pads that are thin-
ner than 1mm.
• Check the thickness/wear of the disc
brake rotors. The minimum thickness is
often printed on the disc.
Derailleur
Shift gears through all the sprocket
combinations to make sure the derailleur
operates correctly and smoothly, and the
chain does not come off.
Pedals
Wiggle the pedals to make sure they’re
secure on the crank arms. Rotate the
pedals on the crank arm. If the pedals
don’t rotate smoothly, see your bike shop
to adjust your pedal bearings.
If necessary, tighten your pedals. The
right pedal is tightened clockwise. The left
pedal is tightened counterclockwise. See
your bike shop to tighten your pedals to
the correct torque.
Crank
Gently wiggle the crank arms and turn the
crank (chainring) with the rear wheel off
the ground.
If the crank feels or sounds loose, or if you
hear a grinding noise when you turn the
crank, do not ride your bicycle.
If your inspection shows that your bike
needs maintenance, take your bike to your
bike shop for service.
