Trek Bicycle Owner’s Manual

Chapter 1: Guide to Safe On- and O-Road Operaon

Powerful brakes

The power of bicycle brakes changes with the

Use Condion of the bicycle. Many models of

modern brakes are very powerful; they are made

to stop a bicycle in wet or muddy condions. If

it is necessary for your bicycle to have more—or

less—power to stop, consult your retailer about

brake adjustments or other brake opons for your

bicycle. Also read Braking on page 8.

Sharp points, moving parts,

hot spots, and pinch points

Some parts of your bicycle can injure you if

mishandled. Sharp points include the teeth of

the chainrings and some pedals. Brakes and

their parts get hot. Moving parts can cut skin

and even break bones. Clamps and pivong

parts such as brake levers can pinch, as can

the chain where it runs on to sprocket teeth.

Aero-bar

An aero-bar is a forward extension of the

handlebar, with arm rests. When riding with your

forearms or elbows on an aero-bar, your ability

steer and stop the bicycle can be reduced. When

more control is needed, change your posion so

that your hands are near the brake levers and you

are not leaning on your elbows or forearms. Also,

do not use the arm rests as handles; they are only

intended to support your forearms when placed

in the center of the pad. Leaning on the edges of

the arm rests could break them.

Frame or fork problem

Frame problems are not common. As an

example of such a problem, some riders could

get a “shimmy” or “harmonic oscillaon” or

“frame wobble” at some speeds.

If you get a shimmy or any other problem,

decrease your speed immediately and do

not ride the bicycle. If your bicycle behaves

in an unusual manner or you hear a noise,

immediately stop the bicycle and idenfy the

problem. Aer any impact, have your retailer

inspect the enre bicycle thoroughly. Repair

any problem before riding again, or take the

bicycle to your retailer for service.

WARNING: A frame or fork

problem could decrease your control

and cause you to fall. If your bicycle

gets a shimmy or any other problem,

decrease your speed immediately.

Take your bicycle to your retailer for

inspection and service.

WARNING: A bicycle is subjected

to wear and high stress. Different

materials and components may react

to wear or stress fatigue in different

ways. If the design life of a

component has been exceeded, it

may suddenly fail, possibly causing

injuries to the rider.

Life span of a bicycle

and its parts

Bicycles are not indestrucble, and their

parts will not last forever. If your use of a

bicycle increases the forces on it through

hard riding, dicult condions, or increased

mileage, you should replace your bicycle or

its parts more frequently than riders who

ride less or ride smoothly and carefully.

The safe life of a part is determined by its

construcon, materials, use, maintenance,

rider weight, speed, terrain, and

environment (humidity, salinity, temperature,

etc.)—so it is not possible to give an accurate

metable for replacement. Any form of

crack, scratches, or change of color in high-

stress areas indicate that the life of the

component has been reached and the part

should be replaced. If you are not sure if you

should replace a part, consult your retailer.

In some cases, a lighter frame or part has

a longer life than a heavier one. However,

beer maintenance, more frequent

inspecons, and more frequent replacement

are necessary for a light-weight, high-

performance bicycle and its parts.
