2009 vs. 2010 SRAM Rival

Wasn’t sure if this qualified as a DQ, and figured it’d be an ever D’er Q to ask if it did.

ANYWAYS, does anyone know the differences between Rival 2009 and Rival 2010? Is there anything significant?

Not sure what that official timing was, but at one point it went from the silver alloy to the black carbon levers. The outer lever changed shape slightly too. I think it also picked up the zero loss mechanism from Red/Force.
