Before the first ride
6.2.2.1 Checking the clamping force of the quick releases
 Open and close the quick releases on the stem or 
the seat post. 
 The clamping force is sufficient if the clamping 
lever can be moved easily from the open final 
position into the middle and has to be pressed with 
the fingers or base of the thumb from the middle 
point onwards.
6.2.2.2 Adjusting the quick release clamping force 
 If the clamping lever on the handlebars cannot be 
moved into its final position, screw out the knurled 
nut.
 Tighten the knurled nut on the seat post if the 
clamping lever's clamping force is not sufficient.
6.3 Adjusting the brake lever
6.3.1 Adjusting 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 
lining and brake disc have reached their wear limit, the 
brakes may fail and cause an accident with injury.
The pressure point setting is adjusted using the twist 
knob.
 Turn the twist knob towards the plus (+) symbol.
If you are unable to set the clamping force, the 
specialist dealer will need to check the quick release.
 Before you set the pressure point, ensure that the 
brake lining and brake disc have not reached their 
wear limit.
