This version was made from a stainless steel tube somewhere from the dismantling of a milk installation. It was round, I think a diameter of 45 mm with a wall thickness of just 1 mm. The bowsprit was a square stainless steel profile of 40 x 40 x 1.5 mm. Convenient that the ball bearings of the footslider could run directly along this profile.

After 5000 km the main tube broke off without prior notice. It was obviously too weak. After this the main tube was reinforced with a crosstree and after a while of faithful service the bike was sold to Olympic wind surfer Bart Verschoor. Unfortunately no pictures.
