Chains; Pedals - DAHON Bicycle Owner's Manual

Chains

Single-speed and three-speed bicycles as well
as many IGH (Internal Geared Hubs) equipped
bicycles use a "1/2 x 1/8" chain that has a
master link.
To reinstall the "1/2 x 1/8" chain, turn the bi-
cycle upside down, and after reinstalling the
chain, pull the rear wheel axle in a rearward
direction. With rotation of the chain, any "tight
spot" and a "loose spot" are due to inconsistent
chain wheel roundness. Adjust the chain so
there is no looseness when the chain is in one
of its "tight spots."
Derailleur equipped bicycles use a narrower
"1/2 x 3/32" chain that has no master link. With
a "1/2 x 3/32" chain, it is necessary most of the
time to use a special tool to push a link pin out
EN
of a chain to separate and remove it. There are
many methods of measuring the chain to deter-
mine if it is too worn. There are some excellent
chain wear indicators for sale at bike shops.
Since the chain rotates a lot more on the rear
wheel than the front, please note that replacing
any already badly worn chain may mean that
you might also need to replace the rear wheel
cassette or freewheel as well.

Pedals

• Toe clips and straps are a means to keep
your feet correctly positioned and engaged
with the pedals. The toe clip positions the
ball of the foot over the pedal spindle,
which gives maximum pedaling power. The
toe strap, when tightened, keeps the foot
engaged throughout the rotation cycle of
the pedal. Toe clips and straps work most
effectively with cycling shoes designed for
use with toe clips. Care should be taken to
become accustomed to the use of toe clips
before riding in traffic.
• Clipless pedals (sometimes called "step-in
pedals") are another means to keep feet
securely in the correct position for maximum
pedaling efficiency. They have a plate,
called a "cleat," on the sole of the shoe,
which clicks into a mating spring-loaded fix-
ture on the pedal. They only engage or dis-
engage with a very specific motion that must
be practiced until it becomes instinctive.
