3T Ergonova Pro -------------------> are you talking about the handlebars we can see also here? (http://www.lfgss.com/thread78671.html)
if so than the link you showed (http://www.3tcycling.com/products.aspx?p=Ergonova) is not the correct one.

but can you tell me if it's a 42cm handlebar?

The link goes straight to the fancy carbon bars but click on the 'Pro' tab and you will see a description. They are 42 cm
and yes those are the bars you can see in the pics
