He would have been 91 years old today, instead we live with his absence for almost two years. Ugo De Rosa left us on March 26, 2023, almost two years ago. How time flies. How the hourglass of life flows: two years without Ugo, one of the greatest fathers of the bicycle. A true artisan, with calluses on his hands and eyes that scrutinized matter, between the glimmer of creativity and that explosion of craftsmanship and engineering, physics and chemistry, all learned on the road and on that wooden workbench that is still there, in Piazza XXV Aprile in Cusano Milanino, testifying to the time that has passed, but does not pass: thanks to memory.
