Chains Pedals
Today, single-speed and three-speed
bicycles as well as many other IGH
(Internal Geared Hubs) systems use
a “1/2 x 1/8” chain with a master link.
To reinstall the “1/2 x 1/8” chain, turn
the bicycle upside down. After reinstalling
the chain, pull the rear wheel axle in the
reverse direction. With the rotation of the
chain, any tight or loose spots are due
to inconsistent chain wheel roundness.
Always keep the chain tight.
Derailleur equipped bicycles use a
narrower “1/2 x 3/32” chain that does
not have a master link. With a “1/2 x 3/32”
chain, it is necessary to use a special
tool to push a link pin out of the chain
to separate and remove it. There are
several methods of measuring the chain
to determine if it is too worn. If chain is
too worn, bike shops sell excellent chain
wear indicators. The rear wheel undergoes
more chain rotation than the front, therefore
note that restoring any worn chain may
mean replacing the rear wheel cassette or
freewheel.
• Toe clips and straps are a way to keep your
feet correctly positioned and engaged with the
pedals. Toe clips are positioned on the ball of
the foot over the pedal spindle, which gives you
maximum pedalling power. When tightened,
the toe strap keeps the foot engaged throughout
the rotation cycle of the pedal. Specific cycling
shoes are designed to work effectively with toe
clips and straps. Prior to riding in traffic, it is
important to be accustomed to the use of toe
clips.
• Clipless pedals (sometimes called “step-in-pedals”)
are another way to keep the foot securely fastened
in the correct position. A plate, called a “cleat”, is
located on the sole of the shoe, which clicks into a
mating spring-loaded fixture on the pedal. The only
way to engage or disengage is with a very specific
motion that must be practiced.
