Cassette Crank bolt Chain Crankset Pedal Figure 2- Drivetrain parts inspecting the crankset and bottom bracket Once a month, clean the chainrings and inspect them for damage. If any teeth are bent or broken, have the chainring replaced by your dealer. Note that on some chainrings, a few teeth have a special shape to enhance shifting.

[. . . ] 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. waRning a damaged carbon fiber part can fail suddenly, causing serious injury or death. 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. 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. There are many variables to this equation: 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. carbon fiber composite inspection procedures Carbon fiber is among the strongest materials used in bicycle manufacture. However, carbon fiber has unique qualities, different from metal parts, and must be inspected carefully for damage. 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. 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 website. If you have any doubts about the integrity of a part, do not ride the bicycle. inspecting carbon fiber parts instaLLatiOn instRuctiOns These instructions explain the steps to remove an existing crankset and install a new one.
