6.6 Longitudinal adjustment of the seat unit (centre of gravity) (Fig. 48)
A profile rail is located on the underside of the seat tube. It is attached on both sides by four
nut sliders.
First loosen the counter nut at the upper end of the adjustment tube. Then loosen the screws on
both sides of the nut sliders (Fig. 48, marking A). You can move the seat tubes lengthwise and
thus, change the centre of gravity. Different adjustment ranges, marked as a grid at the bottom
of the tube, help to move both tubes evenly.
Once you have reached the desired position, retighten all screws.
Ensure that the adjustments at both tubes are parallel and that all screw connections
