If you have an AVL it is not a 2009. It is an '08 or earlier. '09 and up are UCE- unit construction engine model G/C/B 5's.
I thought 2009 was the year they had both AVL and UCE. I met a guy last summer riding an AVL, he told me it was a 2009 . It had a disc brake but not the UCE engine. I have also seen a couple of 2009 UCE bikes.
