As the tension may vary slightly along the belt, this procedure should be carried out on a belt
that is gradually being moved on.
To do this, turn the pedal crank one rotation in
each case and repeat the measurement process
a few times.
If the belt tension is too high or too low,
continue to adjust it until the measurement
result corresponds to the specification.
Tighten the four (6 mm) Allen screws of the right and left belt tensioners on the dropouts.
Rotate the crank 10 – 15 times backwards and forwards and observe the alignment of the
belt in the process. While you are doing so, the belt should only slightly touch the lateral
stop (flange) of the rear sprocket or leave a gap of not more than approx. 1 mm. A consistent
gap of 0.5 mm is ideal.
Wrong
Tightening the axle adjustment screw on the
dropouts on the drive side or loosening it on the
opposite side will guide the belt to be aligned
further in the direction of the lateral stop
(flange) of the rear sprocket.
Adjust the rear wheel, so that the belt is properly
aligned as it moves.
Right
Turn the crank again, check the alignment of the
belt and reset it, if necessary. Repeat this step
until the alignment of the belt is set correctly.
In the process, always adhere to the required
belt tension.
