Mechanical Safety Check - Specialized Roubaix Comp Road Manual De Instrucciones

Routinely check the condition of your bicycle before every ride.
Nuts, bolts screws & other fasteners: Because manufacturers use
„
a wide variety of fastener sizes and shapes made in a variety of materials,
often differing by model and component, the correct tightening force or
torque cannot be generalized. To make sure that the many fasteners on your
bicycle are correctly tightened, refer to the Fastener Torque
Appendix D of this manual or to the torque specifications in the instructions
provided by the manufacturer of the component in question. Correctly
tightening a fastener requires a calibrated torque wrench. A professional
bicycle mechanic with a torque wrench should torque the fasteners on you
bicycle. If you choose to work on your own bicycle, you must use a torque
wrench and the correct tightening torque specifications from the bicycle
or component manufacturer or from your dealer. If you need to make an
adjustment at home or in the field, we urge you to exercise care, and to have
the fasteners you worked on checked by your dealer as soon as possible.
WARNING: Correct tightening force on fasteners –nuts, bolts,
screws– on your bicycle is important. Too little force, and the
fastener may not hold securely. Too much force, and the fastener
can strip threads, stretch, deform or break. Either way, incorrect
tightening force can result in component failure, which can cause
you to loose control and fall.
Make sure nothing is loose. Lift the front wheel off the ground by two
„
or three inches, then let it bounce on the ground. Anything sound, feel or
look loose? Do a visual and tactile inspection of the whole bike. Any loose
parts or accessories? If so, secure them. If you're not sure, ask someone
with experience to check.
Tires & Wheels: Make sure tires are correctly inflated (see Section
„
4.G.1). Check by putting one hand on the saddle, one on the intersection
of the handlebars and stem, then bouncing your weight on the bike while
looking at tire deflection. Compare what you see with how it looks when
you know the tires are correctly inflated; and adjust if necessary.
Tires in good shape? Spin each wheel slowly and look for cuts in the
„
tread and sidewall. Replace damaged tires before riding the bike.
Wheels true? Spin each wheel and check for brake clearance and side-to-
„
side wobble. If a wheel wobbles side to side even slightly, or rubs against or hits
the brake pads, take the bike to a qualified bike shop to have the wheel trued.
CAUTION: Wheels must be true for rim brakes to work effectively.
Wheel trueing is a skill which requires special tools and experience.
Do not attempt to true a wheel unless you have the knowledge,
experience and tools needed to do the job correctly.
Wheel rims clean and undamaged? Make sure the rims are clean and
„
undamaged at the tire bead and, if you have rim brakes, along the braking
surface. Check to make sure that any rim wear indicator marking is not
visible at any point on the wheel rim.
