This doesn't exactly fit under the topic of this thread, but another longevity-related statistic occurred to me after seeing both Rebellin and Ghirmay in the GP Industria & Artigianato results. Ghirmay was born in 2000. That means that Rebellin has competed against riders born in the 2000s, 1990s, 1980s, 1970s, 1960s, and 1950s (Sean Kelly, for example). Has anyone else competed against riders born in six different decades?
