This section explains how to inspect, adjust, and lubricate your crankset.
Once a month, inspect the crankset for signs of fatigue stress. If your crankset is made of carbon fiber, also follow the carbon inspection procedures.
Once a month, clean the chainrings and inspect them for damage. If any teeth are bent or broken, have the chainring replaced by your Trek dealer. Note that on some chainrings, a few teeth have a special shape to enhance shifting.
Every 3 months inspect the crankset and tighten the bolts (Figure 1) to the torque specifications.
