CHAPTER THREE
Inspection, Adjustment & Lubrication
REFLECTORS
Introduction
The reflectors on your bicycle illuminate when a light is
shone on them, directing some of the light back to the source.
In poor lighting conditions, if an oncoming vehicle has their
lights on, the reflectors may help the other vehicle see your
bike. Reflectors are an important part of your bicycle’s safety
equipment. Do not remove the reflectors from your bicycle.
Inspection
Every three months
, make sure all the nuts and bolts
holding the front, rear, pedal, and wheel reflectors are tight.
Check that front and rear reflectors are oriented so their reflec-
tive surfaces are perpendicular to the ground, and that all
reflective surfaces are clean and in good condition. The front
reflector should point directly forward, and the rear should
point directly back. The rear reflector should be at least three
inches below the top of the seat.
Schraeder and Presta Valves
There are two styles of valves used on Gary
Fisher bicycles (Figure 3.8.15), which use different
use techniques for inflation:
• Schraeder valve- remove the valve cap, attach an
• Schraeder valve- remove the valve cap, attach an
air pump with a Schraeder fitting, and inflate. Put
the cap back on, as the cap keeps dirt and debris
out of the valve.
• The Presta valve is also known as a French
• The Presta valve is also known as a French
valve. To inflate a Presta valve, remove the valve
cap, if present. Presta valves seal very tightly, and
require a lot of pressure to open them initially,
so after unscrewing the valve nut, depress the
nut with your finger to open the valve. This
should let a little air out. Inflate using a Presta
valve fitting. After inflation, tighten the valve nut against
the valve stem until finger-tight. This provides the same
function as the valve cap on a Schraeder valve.
