Bicycles should always be protected against falling down. It is often enough to fall from a standing position onto an edge to cause permanent damage to the frame or components. See also „7. Bike transport
and storage".

AFTER A CRASH
DANGER
RISK OF ACCIDENT DUE TO DAMAGED OR BROKEN COMPONENTS!
Crashes or exceptional stresses may cause unnoticed and invisible damages.
• Riding with damaged, bent or even torn parts is extremely dangerous.
• After a fall, the bike and its components must be checked by the PROPAIN service or by a qualified bicycle mechanic.
• Never fix bent parts yourself, but replace them for your own safety.
It is very hard to assess the level of damage of a carbon part. Damages cannot necessarily be seen from the outside. A scratch on the surface can indicate a delamination (a separation of the single carbon
layers). Especially for lightweight bikes, it is often enough to fall down from a standing position to permanently damage frame or components. When suspecting a damage, you should always consult the
PROPAIN service or a qualified bicycle mechanic.
Damages on aluminium parts are indicated by dents, cracks, deformations or discolorations. If you notice any sign of damage, the component or bike must no longer be used. When suspecting a damage, you
should always consult the PROPAIN service or a qualified bicycle mechanic.
