item 1) and turn the cross tube by 90°. Remove the Allen head screws from the cross tube (see Fig. 5, item 2).
3) After adjusting the frame width, position the seat plate:
→ The front of the seat plate is flush with the front of the lateral tubes of the seat frame (see Fig. 33, item 2).
→ The seat plate is centred between the lateral tubes of the seat frame.
→ Install additional seat plate supports if required (see next chapter).
