He retired voluntarily.
It was not after 2009.
It was not before 2000 (and by proxy not before any of those other earlier dates).
He did not win the Giro.
He is on Echoes' list somewhere, sort of, but he is not the mighty El Tarangu.
Edit: it's not him (obviously as I've stated they're on Echoes' list and given some of the facts above) but amazed that Lucien van Impe isn't mentioned, since Echoes surely knows I love me some pure climbers, and Lucien was one of the best...
