Replacing belt sprockets in the event of damage
The belt sprockets must be changed in any case, if they are damaged by significant external
influences. For example, if you hit a rock or a tree root hard with the front belt sprocket
when you are riding the bike, it can bend and would have to be replaced in that case. Stones
that are drawn in and lodge between the belt and the belt sprocket can distort the teeth of
the belt. Teeth can break off in whole or in part. If this is the case, the belt sprocket involved
must also be replaced. Whether the belt should be replaced or not must be decided on the
basis of the relevant criteria of the previous section. (See 75 Belts.) If a drive, in which all of
the components were used for the same length of time, is worn, it is basically recommended
that all of the components be replaced, even if only one component has reached the wear
limit.
Gear cables
The Bowden cables of the gears must be regularly maintained and replaced, if applicable.
This can be the case, especially if the GRACE MX is often stored outdoors and exposed to the
elements.
Handles
Handlebars and handle coverings are susceptible to wear due to their function and must be
replaced regularly where applicable. Handles must always be firmly connected to the
handlebars.
Lubricants
The properties of lubricants change over time. Therefore, all areas to which lubricants are
applied must be cleaned regularly and re-lubricated in order to avoid increased wear to the
parts and the bearings involved.
Handlebars and seat post
Both the handlebars and the seat post are subject to severe dynamic stresses, when the bike
is being ridden. Therefore, check them regularly for visible external damage and replace
them, where applicable. Furthermore, we recommend that these parts be replaced every
two years, if your GRACE MX is subject to heavy use.
