Even if you perform regular inspections, if you exceed the limit of 

strength of a given part, it may fail if overloaded. After any high force 

load, thoroughly inspect all the parts of your bike. High force loads 

include crashes, but you don't have to crash to put a high force load 

on your bike. For example, hitting a large hole in the road or a sharp 

bump such as a railroad track can put large forces on your bike.

The manner in which you ride will determine whether your bike 

and its parts will last. If you ride hard or aggressively, you should 

replace the bike and/or its parts more often than riders who ride 

smoothly or cautiously. When evaluating your use of the fork, there 

are many variables: weight, speed, technique, terrain, maintenance, 

riding environment (humidity, salinity, temperature, etc.), and the 

frame or part itself—so it is impossible to give a precise timetable 

for replacement. But as a rule, it is better to err on the safe side and 

replace the bike or parts more frequently. If you aren't sure, ask your 

dealer. 

Carbon fiber composite inspection procedures

Carbon fiber is among the strongest materials used in bicycle manufac-

ture. However, carbon fiber has unique qualities, different from metal 

parts, and must be inspected carefully for damage.

inspecting carbon fiber parts

Unlike metal parts, carbon fiber parts that have been damaged may not 

bend, bulge, or deform; a damaged part may appear to be normal to a 

cursory glance. Use the following procedures to inspect carbon fiber 

parts:

• Check for scratches, gouges, or other surface problems.
• Check the part for loss of rigidity.
• Check the part for delamination.
• Listen for unusual creaking or clicking noises.

These tests may not be conclusive.

The tests are difficult to describe, so as an aid to describing the tests 

we provide a movie of inspecting a carbon fiber part in the owner's 

manual section of the Bontrager web site. If you have any doubts about 

the integrity of a part, do not ride the bicycle.

a damaged carbon fiber part can fail suddenly, causing 

serious injury or death. inspect a carbon fiber bicycle or parts 

for damage frequently. if you suspect a carbon fiber part is 

damaged, immediately stop riding the bicycle. before riding, 

replace the part or take the bike to your dealer for service.
