Replacing the Sprockets when they have been damaged

The sprockets always need to be replaced if they have been damaged through severe use
or exterior influences. If you ride over a rock, or a tree trunk, for example, and you bottom
out hard with the front sprocket, it might deform and would have to be replaced. Stones
caught between belt and sprocket can cause damage to the teeth of the belt. Teeth
might break off partially or completely. When this happens, the particular sprocket has
to be replaced. Whether or not the belt has to be replaced would have to be determined
with the criteria mentioned above (Replacing the belt after it has been damaged).

Replacing belt and sprockets because of abrasion

Both the belt and sprockets are parts that abrade or wear. Contrary to what you
might expect, tests have shown that the belt tends to have a slightly longer life
expectancy than the sprockets. You can check the abrasion of belt and sprockets
with the Profile Wear Gauge as shown in illustrations 3 and 4. If the gauge result
is equal to, or larger than 0.5mm, the particular belt or sprocket will need to be
replaced. For a drive system in which all components have been used for the same
amount of time it is recommended to replace all components, as soon as one
of them needs to be replaced because of wear or abrasion. You can find further
information about the use of your Profile Wear Gauge in the separate manual.
