6.7 Adjusting the footrests
6.7.1 Adjusting the lower leg length
The required footrest height depends on the lower leg length of the user and the thickness of the seat cushion.
"Angle-adjustable" Footrest, "Fixed" Footrest
1) Loosen the Allen head screws above the footrest (see fig.32, item 1).
2) Adjust the lower leg length (continuously adjustable). The footrest must be inserted at least 60mm into the
frame tube.
3) Tighten the Allen head screws to 8Nm.
"Angle-adjustable/Depth-adjustable" Footrest
The adjustment of this footrest can be fine-tuned as follows:
1) Loosen 2 Allen head screws respectively on each side of the footrest assembly. However, do not completely
unscrew the Allen head screws (see fig.33, item 1).
2) After loosening the Allen head screws, pry the clamp washer out of the bore hole in the cross-tie using a suit
able tool (e.g. screwdriver). Do not remove the clamp washer entirely.
3) Push the footrest assembly up/down slightly around the pivot point (see fig.33, item2). Ensure that the cross-
ties are parallel before re-tightening the screws.
NOTE: During the adjustment process, never loosen the screws (see fig.33, Fig. 1 and Fig. 3) at the
same time.
4) Tighten the Allen head screws to 10Nm. In doing so, ensure that the clamp washer is parallel (not tilted) in the
cross-tie for optimum fixation.
INFORMATION: After each adjustment of the lower leg length, readjust the footrest angle.
