DRIVETRAIN
The drivetrain of a bicycle refers to all parts that transmit power to the
rear wheel including the pedals, chain, chainwheel, 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
follow ing 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.
