This machine appears in the book "Cinelli: The Art and Design of the Bicycle" with Hans-Henrik Orsted training on it.
There is one currently on ebay, first one I have ever seen outside the photo in the Cinelli book, with this description:
"1985 CINELLI D.M. Defaticatore Machine - NOS NIB
Ultra Very rare!
Machine developed by CINELLI from a Patent by prof. Antonio dal Monte (who was in the team that helped Francesco Moser to achieve Hour Record in 1984).
It was used by pistard before and after the race in order to warm-up or cool-down muscles.
Never been used
Complete in every single part, in original box."
Reminder: I invite you to contribute by sending in photographs of
