R. Maintenance of wheel rims
As with all wear pieces, the rim must be checked regularly. If you notice anything strange (unusual
wear or any warping) have your bike checked by a qualified and experienced mechanic. If your wheel
rims show signs of wear, check and if necessary replace them. Reduced wall thickness may lead to
tyre defects and cause injury
S. Appropriate spare parts (tyres, air chambers, friction brake
components, gear components)
When replacing components, it's important to use genuine spare parts. This procedure must be carried out by a qualified
mechanic.
T. Accessories
Maintenance and replacement of accessories must be carried out by a qualified mechanic.
U. Protection of seat springs (excluding children's bike)
A child seat can be mounted on a bike if the seat springs are protected.
Warning:To avoid trapping children's fingers, do not fit the child seat on a bike equipped with unprotected seat springs.
V. Advice on potential damage caused by intensive use
WARNING! Like any mechanical component, a bicycle is subject to significant stresses and strains. Different materials and
components wear at different rates and have different fatigue limits. If the expected life span of a given component is exceeded,
it may suddenly break and risk injuring the cyclist. Cracks, chips and discolouring in high-stress areas indicate that the component
has exceeded its lifespan and should be replaced.
