What to check after a crash
A crash may negatively affect the functioning of the
bike and result in damage. It is possible that your bike
is rendered unusable. For this reason, please perform
the following checks:
Wheels and tyres
Please check your wheels. They must be firmly
positioned in the wheel mounts by means of the quick
releases/quick release axles or screwed connections
and be centred in the front fork and rear fork. They
must revolve smoothly and without any runout. Check
your tyres for damage, particularly to the frame.
Handlebars and front fork
Check the handlebars and front fork for any damage
and cracks. Check to make sure the handlebars and
front fork are not twisted against one another in the
assembly. To do so, hold the front tyre between your
knees and attempt to twist the handlebars.
Derailleur
Please check that your chain is located on the front
chain rings and rear cassette. A crash on the rear
derailleur side may damage it. Attempt to shift through
the gears and make sure the shifter or dropout, which
may be bent, does not come too close to the rear
wheel spokes.
Bent rear derailleur.
Contact between the rear
derailleur and the spokes poses a risk of crashing.
Do not use a bike with a bent rear derailleur. Contact
a bike specialist or the Porsche Bike hotline.
Twisted front derailleur.
A twisted front derailleur
may cause the chain to slip off the chain wheel.
The bike will therefore cease to be propelled forward.
Do not use a bike with a twisted front derailleur.
