Despite regular care, the chain is still subject to wear
and tear. The lifecycle of chains normally corresponds
to approximately 800 - 2500 km or 40 - 125 hours of
use. Replacing your chain regularly can extend the
lifecycle of your chain rings and your cassette.
To easily assess the condition of your chain, shift to
the largest front chain ring and pull the chain off the
chain ring with your thumb and index finger. If the chain
can be lifted substantially, it is excessively elongated
and must be replaced.
Have a bike specialist perform an in-depth inspection
of your chain with special tools.
– Run the belt through the open seat stay and place
it on the back belt pulley.
– Then engage the seat stay lock by applying
tightening torque of 2.7 Nm.
– Now place the belt on the front belt pulley.
Please ensure that the belt is not under tension, if
necessary, turn the eccentric bearing more towards
the back of the bike.
– Now start to turn the eccentric inside bearing until
the belt is under tension and tighten the eccentric
inside bearing by applying tightening torque of
5.5 Nm. Squeeze the belt in the middle of the belt
drive together by applying manual force of 20–45 N
[ 2–4.5 kg ]. You should be able to squeeze the belt
by 10 mm. Repeat this step at various points, in the
process, turn the crank in 45° increments.
– If the belt is not under proper tension, adjust the
tension by turning the eccentric inside bearing.
Bike belt drive
Unlike a derailleur, a belt drive requires no
maintenance, meaning it does not require oiling
or lubrication.
If you have a belt drive, proceed as follows:
– Open the compartment on the right seat stay with
a corresponding M4 Allen key.
– Open the clamp on the eccentric inside bearing
with a corresponding M5 Allen key. You can now
turn the inside bearing counter-clockwise to release
the belt tension.
– Pull the belt off the front pulley.
– You can now run the belt through the open seat
stay.
– Turn the crank so that it is parallel to the chain stay
and pull the belt over the front pulley.
– Follow the steps in reverse order to install a new
belt. First place the belt on the front pulley so that it
is on the inside bearing housing.
Only use original Porsche spare parts when replacing
the chain and select the right chain for your derailleur.
Sudden loss of power and propulsion.
A worn
chain may suddenly break or fall off. The loss of
power and propulsion may cause a crash. Check
the condition of the chain on a regular basis and if
necessary, have it replaced.
Risk of damage due to incorrect belt tension.
If the belt tension is insufficient, the belt may
slip over the pulley and be damaged. Excessive
belt tension may damage the bearings causing
the system to be stiff.
Have a bike specialist change
and adjust the belt.
