Flat tyres
Flat tyres are the most common bike breakdowns.
If you have a spare tube or repair kit, then you can fix
your flat tyre quickly in most cases.
Chapter “Handling the quick releases” on p. 23
describes how to properly mount and remove wheels;
if necessary, you should also observe the notes under
“Mounting the wheels” on p. 47.
If your bike has a gear hub [ Bike S ], you must first
remove the gear cable in order to completely remove
the wheel from the frame.
If your bike has a belt drive, then you must remove the
rear wheel with a size-15 open-end wrench. The belt
is no longer under tension. You must now remove the
gear cable from the Alfine gear hub.
You can now remove the wheel from the frame.
Be careful not to damage the belt when removing it.
Follow the steps in reverse order to mount the tyre.
Use a torque wrench to mount the wheel.
Now check the belt tension. For more details, consult
chapter “Bike belt drive” on p. 42.
To remove the rear wheel of Porsche Bike S with a
derailleur, shift to the smallest sprocket on the cassette.
Pull the derailleur back in order to easily remove the
wheel by pulling it down.
Risk of damage to the brakes when wheels are
removed.
Do not in any case apply the brake lever.
Mount the transport guard for the disc brake in the
brake calliper.
Please consult the instructions provided by the brake
manufacturer.
Hot brake components.
The brake disc and brake
calliper heat up when braking. Under these conditions,
there is a burn risk if your skin comes in contact with
these components. Let the brake components cool off
before you remove the wheel.
