fair enough, he's only 17, but I wouldn't add "only been on the track for a month", coz it's no big deal. There's not much skill required for a pursuit -- all he's got do is get used to the fixed gear. It's not like he's doing a Keirin against 6 of the biggest blokes in the world.
I think LeMond won a similar title on his first ever shot on a track, and Rominger totally smashed the World Hour Record after only a few shots on a fixie
