enough to penetrate tight places, they
should be durable so they can withstand
exposure to the elements, and they must
resist the accumulation of dirt.
Suitable oils include Alsop, Bullshot,
Campagnolo, Finish Line, Lube Wax, Phil
Wood Tenacous Oil, Pedros, Superlube,
and Triflow.
Motor oil, WD40, 3-in-1 Oil, sewing machine
oil, gun oil, and other common oils are not
suitable and should not be used.
In general, applying oil from a drip appli-
cator is superior to using aerosols. Aerosols
promote over-lubrication, which leads to
excessive accumulation of dirt. Apply oil
sparingly. Apply enough oil to do the job,
but not so much that it starts to drip from
the component. After applying any oil,
wipe off the excess.
THREADLOCK
A threadlocking compound should be
used on most fasteners on the A2B Metro.
Threadlocking compound prevents loos-
ening caused by vibration and helps seal
out moisture.
Loctite 242 (blue) or its equivalent is rec-
ommended for threadlocking applica-
tions. Loctite 242 is a medium-strength
threadlocking compound that permits dis-
assembly with common hand tools.
Before applying Loctite to threads, clean
oil, grease, and other residue from the
thread surfaces. Apply a small amount of
Loctite. Excess compound could work its
way down the threads and bond parts
together. Table 5 (this chapter) provides
torque specifications and Loctite recom-
mendations for particular fasteners.
TERMS
Left and Right
The terms left and right in this manual
refer to the rider’s point of view when
seated on the A2B Metro and facing for-
ward. The right side of the A2B Metro is the
chain side. The left side is the brake side.
NOTE, CAUTION and WARNING
The terms NOTE, CAUTION and WARNING
have specific meanings in this manual. A
NOTE provides additional information to
make a procedure easier or clearer.
A CAUTION emphasizes precautions that
must be taken to avoid damage to tools or
the A2B Metro. Disregarding a CAUTION
could lead to mechanical damage.
A WARNING emphasizes a situation where
negligence could lead to injury or death.
Take WARNINGS seriously. Failure to heed a
WARNING could result in serious personal
injury or death.
LUBRICANTS
Grease
In general, use a lithium-based grease
where grease is called for in this manual.
Always use grease made specifically for a
bicycle, such as grease from Bullshot,
Campagnolo, and Shimano.
Oil
Always use oils made specifically for
bicycle use. Bicycle oils need to be thin
