If your product is fitted with an adjustable
pedal bearing support (optional), the pedal
bearing position can be adjusted in angle and
height:

The angle adjustment is done at the top
fork bridge. To do this, loosen the four M6
fastening screws (SW 5 mm), on the clamp
slightly so that the pedal bearing support's
angle can be adjusted using minimal force.
The angle adjustment is continuous (as a
guide, there is a 12° scale fitted). When
you have finished adjusting the angle,
tighten up the four fastening screws to 7
Nm torque and secure them with thread
lock fluid.

To adjust the height, two M6 clamp screws
(SW 5 mm) must be loosened on the pedal
bearing housing. Then the pedal bearing
housing can be moved along the pedal
bearing support to the correct position. Af-
ter this, tighten up the clamp screws to 7
Nm torque and secure them with thread
lock fluid.
Finally, check the chain length and the cable
lengths and adjust them if necessary.

If you want to make a change to the pedal
bearing position, please contact your dealer or
PRO ACTIV.
Please note that, after a large adjustment
to the pedal bearing position, the chain length
and the cable lengths must be adjusted.

18.2.3 Crank length and grip width

The crank length can be chosen from different
lengths individually to suit the length of the
arms and mobility of the user. Different widths
of pedal bearing shafts and spacers between
the crank handles and the rotary axles of the
hand grips are available to adjust the grip
width.
If you want to make a change to the crank
length or grip width, please contact your dealer
or PRO ACTIV.
