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

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trafc.

Clipless pedals (sometimes called “step-in •

pedals”) are another means to keep feet

securely in the correct position for maximum

pedalingefciency.Theyhaveaplate,

called a “cleat,” on the sole of the shoe,
