Exact for Summerhill. He still rides for the Chipottle Development team. I thought that his good results in Colorado would have offered him a contract though.
I didn't remember Chavanel crossed over (except maybe a handful of them for fun). What were his best performances?
Nys targeted a top60 rank in Pietermaritzburg, in order to get a better start position. That was missed but he still has his chance for an Olympic selection.
Some other crossers in South Africa:
9 Marco Aurelio Fontana
37 Geoff Kabush
49 Marek Konwa
50 Julien Taramarcaz (Swiss Champion cyclocross
(On another note, weird to see JC Peraud back to mtb)
Chainel is 35th in the Nokere Koerse and 80th in Milan-Sanremo. He didn't reiterate his great performance from last year.
Oh and I'd like to note Jelle Wallays' great performance in Dwars door Vlaanderen (ex Dwars door België). He was the last to hold Terpstra's wheel. He's not a crosser but raced a few of them last winter, notably the Belgian nats which he finished 16th and dead last.
