» Your Sparc components are well
protected against adverse envi-
ronmental influences. In order to
avoid malfunction due to water
penetration pressurized jets (high
pressure cleaners etc.) should
not be used when cleaning the
bicycle.
» When using the bike during the
winter more frequent cleaning is
necessary to prevent damage
caused by de-icing salt.
