Chapter 3: Inspection and adjustment
This chapter gives instructions for inspection and adjustment
of the parts of a bicycle. The inspections in this chapter are in
addition to those listed in Chapter 1.
Before you perform any work on your bicycle,
read the section
Warning about mechanical
work
on page 12.
To inspect some parts, the part will have to be
disassembled. This type of inspection should
only be done by your retailer.
WARNING:
A bicycle that malfunctions
could decrease your control and cause you to
fall. Fully check all of your bicycle before each
ride. If there is a problem, do not ride your
bicycle; repair your bicycle or take it to your
retailer for service.
A word about torque
specifications
Torque is a measure of the tightness of a
threaded fastener (screw or bolt). The torque is
often written on or near the bolt (on the part).
If the part does not have a specification on it,
check this manual, or ask your retailer.
Use a torque wrench
Make sure you do not apply too much or too
little torque. Too much can stretch, deform, or
break a bolt (or the part it attaches). Too little
allows the part to move and leads to fatigue
breakage of the bolt (or the part it attaches). A
torque wrench (Figure 3.1) provides a precise
measurement of the amount of torque.
Check the function of the part
After you use the torque wrench, perform the
tests in Chapter 1 and in this chapter. If a part
does not have the correct function when it is
tightened to the recommended torque, take your
bicycle to your retailer for service.
If you are not sure of your work, have your
retailer inspect the bicycle after you make
any repair.
WARNING:
A fastener that is either too
loose or too tight can cause damage or break
a part. Use a torque wrench to correctly
tighten a part, or take the bicycle to your
retailer for service.
