Cervélo Owner’s Manual
C. Mechanical Safety Check
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, it is not possible for this
Manual to specify correct torque (tightening force) for each specific
fastener on your bicycle. We can tell you the importance of correct
torque, but not the specific torque required for each fastener on your
bicycle (see Section 4. G). To correctly torque a fastener, a torque wrench
must be used. A professional bicycle mechanic with a torque wrench
should torque the fasteners on your bicycle. If you choose to work on
your own bicycle you must get 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.F.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.
Are both tires in good shape? Spin each wheel slowly and look for
cuts in the tread and sidewall. Replace damaged tires before riding
the bike.
Are both 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 the brakes to work effectively.
Wheel truing 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.
Are both wheel rims clean and undamaged? Make sure the rims are
clean and undamaged along the braking surface, and check for excess
rim wear. See Section 5.A.4.
Brakes: Check the brakes for proper operation (see Sections 4.C).
Squeeze the brake levers. Are the brake quick-releases closed?
All control cables/hoses are seated and securely engaged? Do
the brake pads contact the wheel rim squarely and make full contact
with the rim? Do the brake pads touch the wheel rim within an inch
of brake lever movement? Can you apply full braking force at the
levers without having them touch the handlebar? If not, your brakes
