Idk. The previous poster mentioned this: "to become a star which doesn't only take into account wins/results but also personality and visibility"Define star.
Sagan won 36 races between 2010 and 2012. And half of them were WT races.
He wasn't winning Classics yet, but he was already a very big name in cycling.
For me, Sagan became a star in two months in 2012, when he won 5 stages (4 in a row) in California, dominated the points classification in the Tour de Suisse and the TdF with impressive multiple stage wins.
Back to the original topic, for me Remco is nowhere near that level. He is nowhere near Sagan in terms of results. He may be a star in Belgium, but where I live he is not. So I would not call him a global name in cycling.
