Ridgeback Voyage 2011 or 2012 models

[Ziggy]

My local dealer has a built up Ridgeback Voyage in stock. How can I tell if it is a 2011 or a 2012 model.
I could go to Evans, who no longer stock the older model. But I'm tempted to stick with the local man.

I do not know about the Voyage but the 2012 Ridgeback has a Sora front changer but the 2011 has a Tiagra front changer, so the newer bike has lower specification/cheaper changer.
I could not find any changes for the Voyage from 2011 to 2012 apart from the price.
