A bicycle is not indestructible, and its
parts will not last forever. Our bicycles are
made to withstand the stress of “normal“
riding because those stresses are well
known and understood.
However, we cannot predict the forces
that might occur if you use your bicycle
in competition, if you ride in extreme
conditions, if it is involved in an accident,
if it is used for rentals, or if it is used in
other ways that apply undue high stress or
fatigue loads.
With damage, the life of any part can be
drastically reduced and may fail without
warning. The safe life of a part is deter-
mined by its construction, materials, use,
maintenance, rider weight, speed, terrain,
and environment (humidity, salinity, tem-
perature, etc.), so it is not possible to give
an accurate timetable for replacement.
Any crack, scratch, or change of color in
a high-stress area indicates the part (in-
cluding the frame, fork, or cargo area) has
reached the end of its life and should be
replaced. If you are not sure or you don’t
feel comfortable inspecting your bicycle,
consult your bike shop.
WARNING: A bicycle is subjected to
wear and high stress. Different materials
and parts may react to wear or stress
fatigue in different ways. If the design
life of a part has been exceeded, it may
suddenly fail.
