Can only see Brad Wiggins in the leaders jersey after tomorrow. He's clearly on good form as last week at Bayern Rundfarht showed.
Just checked CQ ranking for ITT's this year for the top contenders when they've raced together:
Paris Nice (27km)- Wiggins 2nd, Vino 1m9s behind, Brajkovic @1m11s, Roche @ 2m47s.
Romandie (20.1km)- Wiggins 4th, Evans @37s, Vino @56s, Brajkovic @ 1m2s, Roche @ 1m58s.
At the TDF last year Wiggins put nearly 2 minutes into Vino over 52km, over 3mins on Roche and 3.5mins on Brajkovic.
Therefore, I can't see past Wiggins for the leaders jersey at worst and he must have a great chance of the win. Of the overall contenders, I can only see Evans challenging him tomorrow.
