6.5.4.4 Setting the pressure point on a

Magura brake lever

WARNING
!
Brake failure due to incorrect setting
If the pressure point is set with brakes where the
brake linings and brake disc have reached their
wear limit, the brakes may fail and cause an
accident with injury.
 Before you set the pressure point, ensure that
the brake linings and brake disc have not
reached their wear limit.
The pressure point setting is adjusted using the
twist knob.
 Turn the twist knob towards the plus (+)
symbol.
 The brake lever moves closer to the handlebar
grip. Re-adjust the grip distance as necessary.
 The lever pressure point activates sooner.

Retracting the brake linings

Disc brakes require wearing-in time. The braking
force increases over time. You therefore need to be
aware that the braking force may increase during the
wearing-in period. The same happens after brake
pads or discs are replaced.
1 Accelerate pedelec to about 25 km/h.
2 Brake pedelec until it comes to a halt.
3 Repeat process 30–50 times.
 The brake disk is retracted and provides
optimal braking power.

Adjusting Suntour fork

Only applies to pedelecs with this equipment
CAUTION
!
Crash caused by incorrectly set suspension
If the suspension is set incorrectly, the fork may
become damaged, meaning problems may occur
when steering. This will cause a crash with
injuries.
 Never ride the pedelec without air in the air
suspension fork.
 Never use the pedelec without adjusting the
suspension fork to the rider's weight.
Notice
Settings on the chassis change riding
performance significantly. You need to get used
to the pedelec and break it in to prevent
accidents.
The adjustment shown here represents a basic
setting. The rider should change the basic setting
to suit the surface and his/her preferences.
 It is advisable to make a note of the basic
setting. This way, it can be used as the starting
point for subsequent, optimised settings and to
safeguard against unintentional changes.

6.5.6.1 Adjusting the negative deflection

Negative deflection depends on the rider's weight
and sitting position. The recommended negative
deflection is between 15% (hard) and 30% (soft)
of the total fork deflection.
