Drivetrain
The drivetrain of a bicycle refers to all parts that transmit power to
the rear wheel including the pedals, chain, chain wheel, crank set and freewheel.
Pedals
Pedals are available in a variety of shapes, sizes and materials, and
each are designed with a particular purpose in mind. Some pedals can be fitted with toe clips
and straps. These help to keep the feet correctly positioned and allow the rider to exert pulling
force, as well as downward pressure, on the pedals. Use of toe clips with straps requires
practice to acquire the necessary skill to operate them safely.
Inspection
Pedals should be inspected every month, taking note of the following areas:
• Check correct tightness into the crank arms. If pedals are allowed to become loose, they will
not only be dangerous but will also cause irreparable damage to the cranks.
• Check that pedal bearings are properly adjusted. Move the pedals up and down, and right to
left, and also rotate them by hand. If you detect any looseness or roughness in the pedal bearings
then adjustment, lubrication or replacement is required.
• Ensure that the front and rear pedal reflectors are clean and securely fitted.
• Also ensure that the toe clips, if fitted, are securely tightened to
the pedals
