WTB GI3-0309 User Manual
Although many catalogs, advertisements and articles about bicycling depict riders engaged in
extreme riding, this activity is extremely dangerous, increases your risk of injury or death, and
increases the severity of any injury. Remember that the action depicted is being performed by
professionals with many years of training and experience. Know your limits and always wear a helmet
and other appropriate safety gear. Even with state-of-the-art protective safety gear, you could be
seriously injured or killed when jumping, stunt riding, riding downhill at speed or in competition.

a. Maintenance
WTB LaserDisc hubs use sealed bearings and protected mechanisms; but, like anything mechanical, they
are subject to wear and corrosion from moisture, dirt and salt. The best maintenance for your WTB hubs is to
clean them with water and a soft brush or lint-free cloth.
clean them with water and a soft brush or lint-free cloth.
Do not use water under high pressure to blast off dirt and mud. The water could penetrate the seals and
damage the bearings and other metal parts.
Periodically lubricate the threads and cam surfaces on the quick release skewer or the threads on the axle
bolts of the Single Duty hub.
Before each use, check brake wear and operation; spoke tension, rim wear, damage and trueness; and tire
fit, wear, damage and inflation. Spin each wheel slowly and look for any signs of damage: dents, bulges,
cracks, or deformation of the rims. Check spoke tension, by spinning the wheel to make
sure it is true (no side-to-side wobble, no up-and-down hop); by squeezing pairs of
spokes to make sure none are loose or broken; and by plucking each spoke to make sure
they all sound about the same. If you discern a difference in tension when squeezing two
adjoining spokes or in the pitch of the sound of a plucked spoke this may indicate a
significant difference in that spoke’s tension. If in doubt about spoke tension or wheel
trueness, do not ride the bike. Take it to a qualified bicycle mechanic.

With rim brakes, check that the wear indicator on the sidewall braking surface is still
clearly visible.
Before every ride, check the tires for excess wear, cuts in the tread and cuts or
bulges in the sidewall. Check the tire pressure of both tires. The tire’s pressure rating is marked on the
sidewall.

CAUTION:
Spoke tensioning and wheel truing is a highly refined skill which requires expensive
special tools and experience. Do not attempt to tension or true a wheel unless you have the
knowledge, experience and tools needed to do the job correctly.

WARNING: Do not ride a bike with a damaged tire or rim. Riding a damaged tire or rim may lead to
sudden tire deflation or improper braking function. Sudden tire deflation or improper braking function
can cause loss of control, resulting in serious injury or death. Replace damaged tires and rims before
riding the bike.
can cause loss of control, resulting in serious injury or death. Replace damaged tires and rims before
riding the bike.
Never inflate a tire beyond the maximum pressure, or ride a tire with less than the minimum
pressure marked on the tire’s sidewall. Exceeding the recommended maximum or minimum pressure
may cause sudden tire failure. Tire failure can cause loss of control, resulting in serious injury or
death.
